NOTE: The instructions here and elsewhere in the manual refer to port designations of the
SV1641HDI, the 16-port version of the Server Remote Control. For other versions, note the
following:
SV841HDI: Ports PC A~H = Ports PC A~D and Ports PC 1~8 = PC 1~4 on your product
SV441HDI: Ports PC A~H = Ports PC A~B and Ports PC 1~8 = PC 1~2 on your product
The restrictions on functions such as cascading and the assignment of master and slave
units also apply to all versions of the product.
1. Ensure that the Server Remote Control unit and the computers to be managed are powered
off.
2. If desired, mount the unit in a standardized rack or cabinet.
3. Connect a standard straight-through Ethernet patch cable to the LAN port on the rear panel
of the unit.
4. Connect the opposite end to your network hub, switch, or terminated wall outlet.
5. If you wish to use the product as a local console, connect a standard keyboard (purple
connector) and mouse (green connector) to the PS/2 ports, as marked on the rear panel.
6. Connect a VGA monitor to the video-out port on the rear panel of the unit.
7. (a) If you are using PS/2 connections to your managed computers, connect the end of the
SVECONxx cable that has three connectors (keyboard, video, mouse) to the keyboard,
mouse, and VGA Out ports on a computer (often a server or other critical system). Connect
the opposite end (with a single VGA-style connector) to one of the PC A~H or PC 1~8 ports
on the rear panel of the Server Remote Control. Repeat this procedure for each PS/2-enabled
managed computer. You will be able to add additional managed computers later with the
Server Remote Control powered on.
(b) If you are using USB connections to your managed computers, connect the end of the
SVECONUSxx cable that has two connectors (USB, video) to an available USB port and
VGA Out port on the computer (often a server or other critical system). Connect the
opposite end (with a single VGA-style connector) to one of the PC A~H or PC 1~8 ports on

8. Power on the Server Remote Control by connecting the AC adapter to a suitable power
source and connecting the opposite end to the DC 12V port on the rear panel of the unit.
9. Power on each of the managed computers, observing normal startup procedures.
NOTE: You can choose to mix managed computers connected via PS/2 and USB connections as
necessary with no impact on features or functionality.
NOTE: Steps 5 and 6 are necessary only if you wish to have the ability to manage the KVM and
its computers locally (i.e. not over the Internet or LAN). While not required, adding these
devices is highly recommended for ease of administration.
NOTE: The KVM also has the ability to “cascade” multiple KVMs to increase the total number
of possible managed computers. If you wish to take advantage of this feature, refer to the section
“Cascade Configuration” in this manual.
Disabling Mouse Acceleration on the Managed Computers
Many operating systems offer a feature called mouse acceleration that allows the user to adjust
the responsiveness of the cursor on the screen to physical movements of the mouse. While this is
usually a beneficial interface enhancement, it can interfere with the operation of the unit and
should be disabled on the managed computers before a remote session is attempted. Follow the
instructions below to disable mouse acceleration for the operating system installed on each
managed computer.
Windows 98
1. From the Control Panel, click on Mouse.
2. From Mouse Properties, click on Motion tab.
3. Make sure the Pointer speed bar is centered and Acceleration is set to None.
Windows 2000
1. From the Control Panel, Click on Mouse.
2. From Mouse Properties, click on Motion tab.
3. Make sure that the Pointer speed bar is centered and Acceleration is set to None.
Windows XP and Windows Server 2003
1. Go to “Pointer Options “ and turn off “Enhance Pointer Precision.”
2. Make sure that the Pointer speed bar is centered.
Linux, Unix and X-Windows
1. Add this command to your xinitrc, xsession or other startup script:
xset m 0/0 0
Network Configuration Methods Explained
The Server Remote Control offers two distinct methods for configuring the unit for your
network. The method that will work best for you will depend on your level of experience and
your specific network configuration.

SVx41HDI Series Server Remote Control: Instruction Guide
Web Configuration Using DHCP
This method requires that your network implement DHCP (Dynamic Host Configuration
Protocol), usually on a server or network access device such as a router that dynamically allows
devices to join the network without pre-configuration. It also assumes that you will have easy
access to your network’s DHCP log, since you will need to know the IP address of the unit to
complete the configuration over your Web browser. (If you are unsure of how to access your
network’s DHCP log, contact your System Administrator for details.) If the unit is powered on
and connected to the network via LAN port on the rear panel, it will automatically attempt to
lease an IP address using DHCP. Before you can begin the configuration process, you will need
to access the DHCP log from your file server or other device that acts as the DHCP server on the
network. A simple DHCP log looks similar to the following:
The information displayed for your own network may vary significantly from the data displayed
in the image, but should supply (at minimum) three essential details: IP address, MAC address,
and device (or machine) name for the computers and other devices connected to your network.
The values for the unit tested above are as follows:
IP Address: 192.168.22.4
MAC Address: 00-0E-C5-00-08-1A
Device Name: (none)
The easiest way to identify your Server Remote Control on the network is by its MAC address, a
unique hardware identifier that is specific to your unit. The MAC address of the unit can be
found on a white sticker on the bottom of the unit. Write down this number and keep it for
future reference. Once you locate the MAC address of your unit in the DHCP log, you can
match it to its leased IP address and proceed with the Web configuration.
NOTE: Once you have located the IP address of the unit switch and wish to proceed with the
Web configuration, do not power off the unit or your DHCP server, since it might lease a
different IP address. Should this happen, re-examine the DHCP log to verify the IP address
again.
Terminal Configuration Using a Serial Cable
Configuring the unit using a serial cable is the best choice if you need to pre-configure the unit
before attaching it to a network, i.e. when sending to a branch office, customer site, etc. or are
not using DHCP on your network. In general, the Web configuration is far preferable because of
its intuitive interface and the fact that you do not have to be within close physical proximity to do
the configuration. However, if you wish to use the serial cable method to configure the Server

Remote Control, you can use any typical communication software package (UNIX: tip, cu,
kermit, minicom; Windows: HyperTerminal, kermit).
Using the DB9 female-to-female null-modem serial cable (provided) connect one end of the
cable to the SERIAL port on the rear panel of the SVx41HDI. Connect the opposite end to the
serial port on the computer you are using to configure the unit. Configure the terminal software
with “8N1” settings:
Connection speed: 115200 bps
No. of bits: 8
Parity: None
Stop bits: 1
Flow Control: None

Configuring the KVM for Your Network
NOTE: As firmware for this product evolves, some of the menu options may change and
therefore these screenshots and instructions may differ slightly from the options displayed on
your screen.
Using the Web Interface
The Web interface is the most intuitive way to configure the Server Remote Control. It also
offers a Java-based VNC client that you can use to control the managed computers from a remote
location. The unit supports any industry-standard HTML Web browser. You can access the
Web interface by opening your Web browser and entering the IP address of the unit you wish to
access/configure. The IP address will be either a) the address assigned by your DHCP server as
identified in the previous section, or b) the address you configure through the terminal via a
serial cable (see the section “Using the Terminal Interface via Serial Port” for more information).
The Login Screen
Before you can access the Web configuration interface, you must
enter a user name and password. The default username and
password as shipped from the factory is username admin with a
password of admin.
NOTE: Before the login screen appears, your Web browser may
display a warning about an invalid security certificate. This does not affect the security of your
data in any way. Whenever you are prompted about a certificate security problem by your
browser or the Java VNC client, always choose the option to continue. For more
information, please consult Appendix A, “About Security Certificate Warnings”.
The Home Screen
The Home screen serves two functions. First, it is a place to check the status of the unit, view
essential system information, and
capture screen shots from the
managed computers. Second, it is
where you can start the integrated
Java VNC client to interact with the
managed computers by clicking on
the large screen shot or choosing one
of the VNC client links.
The Admin/Setup Screen
This is the menu that will allow you
to access all the features you will
need to perform an initial
configuration of the Server Remote
Control. Each of the options is
explained in detail here.

(DHCP)
Automatic network
configuration using DHCP
is: Enabled/Disabled.
This feature applies to the
LAN port on the rear panel,
and is enabled by default.
When enabled, the unit will
automatically configure
itself with an IP address
when a DHCP server is present. When disabled, the LAN port will use the values
assigned to it on the IP Addresses and Routing table below.
IP Addresses and Routing
This table allows you to assign IP information for the LAN port. If you are using DHCP,
the values for the LAN port will be filled in automatically and any changes made will not
affect the setup.
Domain Name Server (optional)
This section allows you to specify DNS servers and the default DNS domain suffix in use
on the network. If DHCP is enabled, some of these values may be supplied
automatically.
Commit Network Changes
Clicking the Commit button applies any changes made on the page to the configuration,
but leaves the old settings
active until the next time
the unit restarts. Clicking
Make changes effective
now applies the changes
and restarts the unit so the
new settings take effect
immediately.
User accounts: add, delete and
change passwords
This menu will allow you to add
accounts other than admin to the
system. These accounts will not
have the authority to change settings, but can access the Web interface and log in the VNC

console. Selecting Delete permanently removes the user from the system. If you enter values
for a user that does not already exist under Edit User Details, the system will create that user for
you when you click Record changes. If the user already exists, you will change the password
for that user.
Change system identification
Provides details about this unit that will be available to DHCP servers, SNMP agents, and
VNC clients. While these values do not affect the operation of the unit, they make it
easier to manage on the network.
Security policy, internal firewall and admin password.
This menu allows you to
configure a number of
settings, including
changing the default
password for admin
(recommended). Read and
consider the comments
and instructions on this
menu before making any
changes, as changing these features could make the unit inaccessible through Web
configuration (i.e. due to firewall filtering). Note that any password changes you make
will have to be entered in duplicate to prevent the chance for error.
Setup compatibility with host system, external power bar.
This menu allows you to configure
the unit for use with products such as
the StarTech.com Serial Control
Power Switch and locale-specific
items such as a non-English
keyboard. When the StarTech.com 8-
outlet Serial Power Console Switch is
selected as the external power bar,
additional menu choices will appear
on the main page of the Web
interface. See the documentation for
the StarTech.com Serial Control
Power Switch for more details on how to access and configure this feature.

Debug network setup values and routing.
Takes you to the Status menu (see below).
SNMP agent setup and configuration.
This menu allows you to configure the unit so it can be recognized and managed using
industry-standard Simple Network Management Protocol software.
RADIUS authentication setup.
The RADIUS server requires the IP
address, the UDP port number
(1812 - default or 1645) and the
shared secret. The shared secret is
used to encrypt communications
and corresponds to a shared
password for the RADIUS server
and the client machine. Two
additional servers may be defined
for backup purposes. Each server
will be tried in order, using the
indicated number of retries and
timeout period, which are configurable on the same page. Remember to enable RADIUS after
configuring it. While RADIUS authentication is enabled, the locally defined accounts on the
KVM control over IP module will not be used, except for the SSH login. However, if a user
name of the form “name.local” is given at the RADIUS prompt, the system will use “name”;
check the password locally, and skip RADIUS authentication. Delete all local accounts to avoid
this behavior. When connecting via VNC, a login screen is generated that asks for a RADIUS
username and password.
Additional RADIUS challenges
may be demanded depending on
the RADIUS server in use. This
allows operation with hardware
tokens and other advanced
authentication devices.

Auto Self Upgrade
The unit includes an
innovative feature allowing
the unit to upgrade itself
over the Internet. Simply
click on the button labeled
Upgrade to latest and the
module will go out to the Internet and download the latest version of the system firmware
and then install it. If the module cannot access the Internet directly (perhaps due to a Web
proxy or other firewalls), then a page will be shown that causes your browser to
download the required file. Save this file to disk and then upload it as described in the
next section, Manual Upload. The main FPGA is upgraded separately, and has its own
Upgrade button. This file is unique for each unit, so it must be done in this manner.
If you have multiple units to upgrade, you may choose the Get latest version button that
will not attempt to upgrade the unit directly, but will instead fetch the required file. This
file can be uploaded to multiple units manually. You may also choose Reboot Myself at
the bottom of the screen to restart the unit without powering on and off.
Manual Upload
Enter the name of the firmware file that you received from StarTech.com into the field
provided (or use the Browse... button). Press Start Upload and wait until a successful
upload message is shown.
NOTE: Remember the following during the firmware upgrade…
•
Do NOT turn off power to unit before this operation completes successfully. It
may take several minutes to write to flash memory.

•
The unit will sometimes reboot as part of the upgrade procedure, depending
on which system component is upgraded. You will have to reconnect and re-
login in those cases.
Wait at least two minutes after pressing Start. Do not assume the upload did
not work. There is no status indicator bar to show the progress of the upload.
The upload could simply be slow.
Each file that is distributed upgrades a different component of the system.
Therefore, be sure to apply all files you are given as part of an upgrade. The
system knows what to do with each file you give it, and they are checked for
validity before being applied.
Software Options Upgrade
Certain firmware features may be offered separately from the base unit, in order to reduce
the initial cost for the Server Remote Control.
NOTE: If you wish to upgrade after the system is in operation, go to the Manage
Firmware page and scroll down to the section entitled Purchase Options.
Look for a unique code, like the following one:
4-C80C-B960-1-0
If you provide this code to the technical support department, they can give you an unlock
code that will open any feature you request. Types in the code provided, exactly, into the
area provided and click “Submit”. The new features opened by the code will be enabled
immediately, but you may need to reboot the unit to begin using certain features.
Status Screen
This screen displays a system security log, various system settings, and the ability to generate a
copy of the system configuration in plain text format.
Port Numbers
This table allows you to change TCP port values for services available on the unit. By default,
they are factory-set to common Internet values. You may wish to enhance security by disabling
services that you will not
use with the unit. To disable
a service, change its port
number to 0. When you
have made any necessary
changes, click Commit
Changes to use the settings
the next time the unit
restarts. To force the unit to
restart immediately, click
Restart Servers.

Accessing the VNC Interface
There are three ways to communicate with the Server Remote Control in order to control the
managed computers:
•
•
•
Web interface: The integrated Web server includes a Java-based VNC client. This
allows easy browser-based remote control.
Native VNC client: There are several third-party software programs that use the
standard VNC protocol, available in open source and commercial VNC clients.
SSH access: By default, there is a standard SSH server running on port 22 (the
standard SSH port). Once connected via SSH, the VNC traffic is tunneled through the
SSH connection and encrypts the VNC session. Each method will be discussed
briefly in the following section. The type of encryption method or client used is not
critical.
NOTE: The first time the Server Remote Control is accessed, it defaults to the PC 1 port on the
master switch as the default managed client to display. If there is no computer/slave KVM
connected to that port, you will see a blank screen until you switch to a port with an active
managed computer. For future sessions, the unit will default to the last port accessed when
beginning a VNC session, assuming the unit has not been upgraded or reset.
Web Interface
The Java-based VNC client that is integrated into the unit’s interface requires a browser with
cookies and JavaScript enabled. To start the Java VNC client, login to the Web configuration
13

SVx41HDI Series Server Remote Control: Instruction Guide
interface and click on the thumbnail of the desktop on the Home menu, or follow one of the two
links on that page:
Java VNC with no
encryption (faster).
Java VNC with SSL
encryption (more secure).
You may need to upgrade
your Java support in your
browser; however, most
modern browsers come with
a version of Java that is
compatible with this
application.
The Java VNC client makes
a connection back to unit
over port 5900 (by default) or 15900, if encrypted. The encrypted connection is a standard SSL
(Secure Socket Layer) encrypted link that encrypts all data from the session, including the actual
video pictures.
Because Java is considered a “safe” programming language, the Java VNC client has some
limitations. Certain special keystrokes cannot be sent, such as Scroll Lock on the keyboard.
This client software requires the use of Java 2 (JRE 1.4) to enable features like wheel mouse
browser and operating system is up-to-date.
Native VNC Client
This system implements the VNC protocol, so any off the shelf VNC client can be used. There
are over 17 different VNC clients available and they should all work with this system. This
system automatically detects and makes use of certain extensions to the basic RFB protocol that
is provided by the better VNC clients.
Linux, MacOS and many versions of Unix. Source code for all clients is available there too. This
version of VNC is being actively developed. The authoritative version of VNC is available from
the original developers of the standard. For a commercial, supported version of VNC, you should
contains a number of enhancements for use in a larger corporate environment.
NOTE: Some native VNC clients may require a flag or setting indicating they should use
BGR233 encoding by default. If this flag is not set, you may see a garbled picture and the client
will fail. The Unix versions of VNC require the flag -bgr233. For examples on using this flag,
review the commands in the following section.
14

SVx41HDI Series Server Remote Control: Instruction Guide
SSH Tunnel (with Native VNC client)
If you are using openssh, here is the appropriate Unix command to use, based on the default
settings on a machine at 10.0.0.34:
ssh -f -l admin -L 15900:127.0.0.1:5900 10.0.0.34 sleep 60
vncviewer -bgr233 127.0.0.1::15900
Notes:
•
A copy of these commands, with appropriate values filled in for your current system
setting, is provided in the on-line help page. This allows you to “cut-and-paste” the
required commands accordingly.
•
•
You have 60 seconds to type the second command before the SSH connection will be
terminated.
The port number “15900” is arbitrary in the above example and can be any number
(1025...65535). It is the port number used on your client machine to connect your
local SSH instance with the VNC client. If you want to tunnel two or more systems,
you will need to use a unique number for each instance on the same SSH client
machine.
•
Some Unix versions of the VNC client have integrated SSH tunneling support. Some
clients require your local user id to be the same as the userid on the system. Use a
command like this:
vncviewer -bgr233 -tunnel 10.0.0.34:22
Using the VNC Menu
One of the unique features of this product is the VNC menu system. Whenever you see a window
with a dark blue background and grey edges, this window has been inserted into the VNC
datastream so that it is effectively laid over the existing video. These menus allow you to control
the many features of the KVM without using the Web interface or a custom client.
The commands you send through this interface (i.e. restart) will be sent to the managed
computer currently active on the Server Remote Control. It is advisable to verify which
managed computer is active before making any changes. We strongly recommend you
thoroughly familiarize yourself with the information here and in the next section
(“Accessing KVM Features”) before undertaking any critical tasks through the VNC
interface.

Welcome Window
When you initially connect to the system, a window similar to this one will be shown.
This tells you which system you are controlling, what encryption algorithm was used and what
key strength is currently in effect. Click anywhere inside the window to clear it, or wait ten
seconds.
Bribar Feature
Along the bottom of the VNC screen is a dark blue bar with various buttons. We call this feature
“the Bribar”. Its purpose is to show a number of critical status values and to provide shortcuts to
commonly used features.
Here is a snapshot of what it may look like. There will be slight differences based on optional
features and system configuration. Starting from the left side of the Bribar, each feature and its
function is outlined below.
Bandwidth: Indicates current average bandwidth coming out of the KVM control over IP
module. The second number measures round trip time (RTT) of the connection when it
was first established.
Resync: Re-aligns the remote and local mouse points so they are on top of each other.
Redraw: Redraws the entire screen contents; occurs immediately.
PS/2 Reset: Resets the PS/2 keyboard and mouse emulation. Useful to recover failed
mouse and/or keyboard connections.
÷4, ÷8: Switches to thumbnail mode, at indicated size.
Ctrl-Alt-Del: Sends this key sequence to the host. Works immediately.
Alt-F4: Sends the key sequence to host (closes windows).
1~8, A~H: Switches the current view to the specified KVM port. This function works
for the master unit only. Use the KVM menu (see below) to access KVM functions on a

Main Menu
To access the main menu, press F7 twice quickly. You must press the key twice within one
second. If you press it once or too slowly, then the F7 key(s) are sent to the host, just like any
other key. This is the only way to get into the menu system, if the Bribar is disabled. Here is the
main menu for a typical system:
The main menu window may be moved by clicking and dragging on the title bar. It can be closed
by pressing Escape, or by clicking on the red X in the top right corner.
Here is a guide outlining various fields from the Main Menu. Most of the functions operate
immediately. Other functions require a response to a confirmation prompt first before performing
the requested function.
•
Identification: Fixed text label that is defined by the user in the Web interface. This does
not affect the operation of the system and is intended to assist with administration.
Status: Current status of the attached system and the status of the module.
B/W Min/Avg/Max/Auto: Bandwidth control. The white button is the mode the system is
currently operating. If you choose Min/Avg/Max then you will override the default, Auto.
As the automatic mode measures actual network performance, you may see the current mode
switch from Min up to Avg or Max. The different modes indicate more time spent on
compression versus more bandwidth. There is no visual difference between the modes, but
there can be a noticeable difference in speed and smoothness.
•
•
•
•
•
Mouse Resync: Resynchronizes the mouse pointer so that the local and remote mouse
pointers are on top of each other.
PS/2 Reset: Resets the PS/2 emulation going to the host and to the attached PS/2 devices.
This can be used if the mouse stops responding or the PS/2 keyboard isn't working.
Take Control: When multiple users are connected to the same system, use this button to take
control away from another user. Only one user may control the keyboard and mouse at any
time. All users see the same picture.

•
KVM Menu: Allows access to the menus on a slave KVM unit.
Bribar: Closes or reopens the Bribar window along the bottom of the screen.
VirtKeys Menu
Clicking any button in the top half of the window simulates pressing and releasing the indicated
key. In the bottom area of the screen, clicking will simulate the indicated Meta key being
pressed. You may then click in the top part to send another key and release the Meta key at the
same time. Alternatively, you may move the mouse outside this window, press the regular key,
and then choose -RESET- to release all depressed keys.
The VirtKeys menu can be left open while using the host system. You can then click the required
button at the suitable time, and still interact with the host in a normal fashion.

SVx41HDI Series Server Remote Control: Instruction Guide
Use the Auto Everything button to automatically fine-tune all three adjustments. If the test
pattern for Color Offset calibration is not present on the screen, then the Color Offset adjustment
is skipped.
Changes/frame indicates the number of 16x16 blocks of video that are being sent, on average,
for every frame of video. With a static image being displayed by the server, this number will be
zero (shown as -nil-). Moving the mouse, for example, will cause the number to jump to about 2
or 3. You may use this number to judge the picture quality as you adjust the controls on this
menu.
Picture Positioning affects the image position on your screen. If you see a black line on either
side of your screen, or at the top or bottom, you can use the arrow buttons to shift the image in
that direction. Pressing Auto does the same thing for you automatically. Use Save to save the
changes you have made manually. Since this adjustment depends on the video mode, separate
values are stored for each video mode.
Color Offset is a fine tuning adjustment that requires the use of a test pattern. There is a copy of
the test pattern available on the Help! menu of the integrated web server. You must arrange for
that image to be shown on the managed computer. Do not allow scaling, cropping or any other
changes to that image. Press the Auto button and the system will calibrate color for the best
possible picture in approximately one minute. If the system cannot find the test pattern on the
screen, it will say so. Check that the pattern isn't scaled or covered up. It's important to do this
operation in 24-bit or 32-bit color video mode (i.e. true color). Although the algorithm may work
in 16-bit or 8-bit color video modes, the results will not be optimum and usually it won't be able
to recognize the test pattern.
Pressing the Advanced button will open the Advanced Video Tuning menu. While the vast
majority of users will not need to adjust these settings, it offers a high-degree of control of the
video settings of your VNC sessions. See Appendix B for more information on this feature.
Sampling Phase does not normally need to be used since our system tunes the sampling phase
whenever the video mode changes. This button does not require a test pattern, but will perform

optimally when used with our standard test pattern. For your reference, the sampling phase
number is shown to the right of the Filtering button.
Noise Filter controls the advanced video filtering of our system. Unlike other filtering
algorithms, our noise filter will only remove noise. It does not degrade the signal quality or
readability of small text. You may turn it on and off using the indicated button, or set it to other
values using the arrows. Higher numbers cause more filtering and may cause artifacts when
moving windows. The most common visual artifact is a vertical line dropping when moving
windows horizontally. You may use the Redraw button to correct these, or use a lower filter
number. At minimum, these values must be greater than two.

Accessing KVM Features
Once you can access and configure the networking component of the Server Remote Control,
you can use it to select and control the managed computers connected to it. This section
describes how to add additional KVM switches to the master unit for greater flexibility, and how
to use the on-screen display (OSD) system to manage your computers. Once you have
established a VNC session with the SVx41HDI, you can access the KVM features as though you
were at a local console.
Cascade Configuration
You can connect a second level of KVMs to one or more of your Master Server Remote
Control’s PC x ports. The KVM switches connected to the Server Remote Control (the “Master
switch”) are known as Slaves. Once connected, the units will automatically configure themselves
as either Masters or Slaves. You can only connect an equal or “smaller” KVM to the Master: a
16-port master Server Remote Control switch can have both 16-port and 8-port KVM slaves, an
8 port Master Sever Remote Control switch can have 8-port and 4-port Slaves, and so on.
For example, the 16-port unit can support 136 computers, with 8 16-port Slave KVMs, each
connected to 16 computers. The Slave KVMs must be connected to the PC 1~8 ports, not the PC
A~H ports.
To cascade your KVMs, use a 3-in-1 PS/2 KVM cable to connect one of your Master switch’s
PC ports to the Slave switch’s PC 1~8 ports. When turning on your cascaded switches, turn on
the Master switch before turning on any of the others.

Hot Key Commands
A hot key command is a short keyboard sequence to select a computer, activate a computer scan,
etc. A hot-key sequence starts with two Left Control keystrokes followed by one or two more
keystrokes.
The short form hot-key menu can be turned on as an OSD function (<F4>: More\Hotkey Menu)
every time the left <CTRL> key is pressed twice.
Left Ctrl refers to the <CTRL> key located at the left side of the keyboard.
1~8/A~H refer to the number keys 1 to 8 at the upper row of the keyboard (Do not use the
keypad at the right of the keyboard) and character keys A to H (case insensitive).
Selecting a Computer
To select a computer by hot-key command you need to know the device’s channel address,
which is determined by the KVM connection. For a computer connected to the Master switch,
the address is represented by the PC port number (1~8 or A~H). For example, to access the PC
plugged into port 7 of the Master KVM switch, type:
left Ctrl + left Ctrl + 7
For a computer connected to a Slave KVM, you need to know the channel address of the Slave
unit (1~8) and then the channel address of the device (1~8 or A~H). (Please note that only
Master's PC 1 to PC 8 ports can be connected to a Slave.) For example, to access the computer
plugged into port C of a Slave KVM Switch that is plugged into Port 6 of the Master switch,
type:
left Ctrl + left Ctrl + 6 + C
Auto Scan
Auto Scan automatically scans through powered computers at a fixed interval:
left Ctrl + left Ctrl + F1
When Auto Scan detects any keyboard or mouse activity, it suspends the scanning until activity
stops; it then resumes with the next computer in sequence. The length of the Auto Scan interval
(Scan Rate) is adjustable (see Scan Rate on the following page). To abort the Auto Scan mode,
press the left Ctrl key twice.
NOTE: The Scan Type setting will determine whether computers must be eye-marked to be
included in the scan. See page 25 for details.
Manual Scan
Manual Scan enables you to manually switch back and forth between powered computers:
left Ctrl + left Ctrl + F2
Press the up or down arrow to select the previous or next computer in sequence. Press any other
key to abort the Manual Scan.

Scan Rate
Scan Rate sets the duration between switching to the next computer in Auto Scan mode:
left Ctrl + left Ctrl + F3
The unit switches between scan intervals of 3, 8, 15 and 30 seconds.
Keyboard Typematic Rate
You can adjust the keyboard typematic rate (given in characters/sec). This setting over-rides the
keyboard typematic rate of your BIOS and any operating system.
left Ctrl + left Ctrl + F4
The unit switches between rates of 10, 15, 20 and 30 characters/sec.
Audio Stick
A multimedia module can be LINKed to the back of the master KVM for selecting microphone
and stereo speaker signals. There are two options for Audio Stick: On and Off. When set to On,
audio selection follows computer selection. When set to Off, audio selection stops following
computer selection. It is useful if you want to listen to a particular computer's audio signal while
operating other computers.

Forgotten master password.
You can reset the master password using the serial interface on the module. Use the S command,
and type a new password. The old password is not required for this procedure.
Remote mouse and local mouse don't line up.
Use the “mouse resync” command in the main menu or press the “Resync” button on the Bribar.
If the mouse pointers still don't line up, verify that mouse acceleration has been disabled.
NOTE: The Windows login screen does not accept the “mouse acceleration” option, and always
has the mouse accelerated regardless of your configuration. Therefore, on this screen it is best to
avoid using the mouse.
After resync, mouse is still a little bit off.
Use the video adjust menu to position your video image exactly where it should be. Normally a
slight video positioning error is perceived as a mouse sync issue. A video positioning error is
visible as a black line along the top or bottom (and right or left) edges of the remote screen.
Remember to save your position changes!
Cannot login via SSH.
Remember to use either “admin” or a username created in the system as the user name you give
your SSH client.
If you see a warning about “identity of host cannot be verified”, and a question about saving the
host's fingerprint, this is normal for the first time you connect to any machine running SSH. You
should answer “yes” so that your SSH client saves the public key of this host and doesn't re-issue
this warning.
Certificate warning shown when connecting via HTTPS.
It is normal for a warning dialog to be shown when connecting via HTTPS. The SSL certificate
we use is created when the unit is first produced. It does not contain the correct hostname
(subject name) because you can change the hostname as required. Also, it is not signed by a
recognized certificate authority (CA) but is signed by our own signing authority. For more
details, refer to Appendix A, “About Security Certificate Warnings.”

SVx41HDI Series Server Remote Control: Instruction Guide
Appendix A: About Security Certificate Warnings
What is a security certificate?
Sites that employ secure TCP/IP (Internet) connections include a certificate that confirms that
users are connecting to a legitimate site and are not being redirected without their knowledge.
Certificates are issued by trusted third parties called Certificate Authorities (CAs) and contain
essential details about a site that must match the information supplied to your Web browser.
Why do I receive a warning when I access the login screen on the SVx41HDI?
As it redirects you to a secure (SSL) session by default, the login screen may generate a warning
from your Web browser or the VNC Java client for two different reasons. First, the CA that has
issued the certificate on StarTech.com’s behalf may not yet be recognized as a trusted source by
the computer you are using to access the SVx41HDI. Second, since the unit could be configured
in a number different ways, it is impossible to supply a generic certificate that will match your
exact network settings.
Is my data safe?
Yes. The security certificate does not affect encryption effectiveness in any way, nor does it
make the Server Remote Control any more vulnerable to outside attacks.
Can I prevent the warning from occurring?
Yes. You have two options that may prevent the warning from occurring. First, if the Web
browser you are using offers the option to ignore the warning for future visits, the browser will
no longer generate a warning if that option is selected. Second, if you install the certificate from
the KVM onto the remote computer (see below) and if the unit is configured with a domain name
ending in .com, .net, .org, .gov, .edu, .us, .ca, .uk, .jp, or .tw (i.e. remotecontrol.mydomain.net)
then the warning should no longer occur.
Installing the new certificate…
The following instructions detail how to install the certificate from the SVx41HDI onto your
local computer (in this case, running Windows XP and Internet Explorer).
1. Open your Web browser and go to the KVM login screen. Click the update security
certificate link.
2. When prompted, choose Open.
3. A Window will appear that offers information about the certificate. Click Install
Certificate.
4. The Certificate Import Wizard will appear. Select Automatically select the
certificate store… (default) and click Next. When the next window appears, click
Finish.
5. A confirmation dialog will appear asking you if you wish to install the certificate. Click
Yes.
6. A message should appear saying the import was successful. Click OK.

Appendix B: Using the Advanced Video Tuning Feature
The Advanced Video Tuning menu allows you to adjust the qualities of the video in your VNC
sessions, and can be accessed by clicking the Advanced button on the Video Tuning VNC
menu. While many users will probably allow the SVx41HDI to automatically configure the
video properties, you can use this menu to exercise a great deal of control over the settings if you
wish.
The Presets section contains up to sixteen different settings plus the factory setting. If a number
is highlighted, as in the example shown, then that preset has been programmed with valid
settings and may be used. Note that the Factory preset is always available. Simply click on the
appropriate button and those settings will be restored.
To save settings to a preset, click on the Save->Preset button in the Actions pane. The preset
buttons will highlight. Click the desired preset button to save the values. Note that any previous
settings assigned to that button will be lost. If you do not wish to save the presets after clicking
the Save->Preset button, click the Save->Preset button a second time and the save function will
be canceled.
The section of the screen marked Current Values indicates the various video parameters that
can be adjusted. For each parameter, there are a series of buttons: [, <<, -, Auto, +, >, ]. The ’[’
and ’]’ buttons set the parameter to its smallest value or largest value, respectively. The ’<<’ and
’>>’ buttons decrement or increment the parameter by a large amount. In the case of phase, this
is 4 units. For all the others, this is 10 units. The ’-’ and ’+’ buttons decrease or increase the
parameter by one unit. The middle button sets the parameter to the middle value. The text of the
middle button also indicates which parameter is being controlled. Note that in the case of phase,
the middle button invokes the auto-phase algorithm.
The Performance section of the screen gives an indication of the quality of the video.
Changes/frame is the average number of tiles that change for each frame sampled by the
hardware. Flatness is an indication of what percentage of the screen contains tiles that are
comprised of only one color.
The Regrab Screen button in the Actions section causes the screen to be re-captured. When
making small changes to the video parameters, sometimes these changes are not reflected in the

SVx41HDI Series Server Remote Control: Instruction Guide
displayed screen immediately, particularly if the noise filter is enabled. Press this button to see
the immediate effect of the changes.
Use the Show Diffs button to learn which parts of the screen are being sent over the Internet.
When you click this button, the screen is cleared to a medium grey color. All blocks that are sent
from that point on will show up on the screen as they are sent. Click the button again to reset the
screen to grey. To return to normal operation, click the Regrab button. It is very easy to visually
identify the effect of noise on the signal processing using this feature.
The Auto Offset & Gain button in the Actions section invokes the automatic algorithm for
setting the video parameters. The algorithm requires the factory calibration test pattern to be
correctly displayed on the screen.

Appendix C: Getting Peak Performance
Choose the best video mode
•
We recommend using 60Hz refresh rate and 1024x768 resolution. Using a smaller resolution
like this allows you to fit multiple windows on your remote desktop. Higher refresh rates
stress the video card's quality and do not provide any additional information or benefit.
Noisy video cards
•
A digital KVM works by converting the analog video signals emitted by your video card into
digital data. If there is noise on that signal, then it must be digitized and sent over the
network too. The name brand, quality video cards have, in our experience, better
performance simply because they don't add analog noise.
•
•
Some external KVM switches generate video noise too. Try to keep cables short to reduce
the effect.
Enable the Noise Filter option (on the Video Tuning menu) to mitigate noise issues.
Network performance
•
The Server Remote Control will always send as much data as it can, given what's happening
on the screen and the actual network performance. When nothing is changing on the video
screen, zero bytes are sent over the network. If the whole screen is changing, then the module
will send as much data as your network connection and VNC client can handle while not
allowing it to fall behind.
•
Network latency, which is the total time it takes for a packet to get to the KVM and come
back, has the biggest impact on perceived performance and usability. Network bandwidth has
a lesser effect, particular when just moving the mouse around. Only a few bytes need to be
sent when the mouse is moving (and nothing else is changing on the screen), but the round-
trip-time limits the hand-eye coordination of the user if it is too great. Both actual bandwidth
and measured network latency are shown in the Main Menu.

Appendix D: The IPMI Upgrade Option
Background
To offer a more complete remote server control solution, the SVx41HDI offers an optional
power management feature that allows remote hardware restarts and the ability to power the a
managed computer on and off. You may be able to take advantage of this feature if the computer
you are managing supports IPMI (Intelligent Platform Management Interface). Note that only
one managed computer can use this feature at any one time.
Managed Computer Requirements
The managed computer must support the IPMI standard version 1.5 to use this option. Most
popular server motherboards now support the IPMI standard. To determine if your computer
supports this IPMI, consult its documentation for more information.
IPMI is used to configure and control a device on the motherboard called the BMC (Baseboard
Management Controller) using a dedicated serial port. Once the computer is configured for
IPMI management, the serial port on the managed computer is normally reserved by the BIOS
solely for that purpose and cannot be accessed or recognized by the operating system. It is
therefore unlikely that a serial port provided by an add-in card will be able to act as an IPMI port,
so you must use a serial port integrated on the motherboard of the managed computer. If the
computer you are managing only has a single serial port, you must add an additional port (or
ports) via an add-in card if you need a serial port for other purposes (i.e. modem). Enabling
IPMI support usually requires enabling options in the managed computer’s BIOS setup software,
and the instructions will vary considerably from make to make and model to model. Normally, a
password will be created by the BIOS that allows the IPMI feature to be accessed; this password
is exclusive to the IPMI feature and does not correspond to a password or account in the
managed computer’s operating system.
If the Managed Computer Does Not Support IPMI
If the managed computer you wish to monitor with the SVx41HDI does not support IPMI,
StarTech.com offers a non-IPMI solution that also works via serial port and acts as a power
concentrator and a power management device: the 8 Outlet Serial Power Console and Switch
your local StarTech.com dealer.

Connecting the SVx41HDI for IPMI Control
The SERIAL port on the rear panel requires the use of a null modem serial cable. Connect one
end of the serial cable to the serial port that is configured for IPMI access on the managed
computer. Connect the opposite end to the SERIAL port on the SVx41HDI.
Configuring IPMI on the SVx41HDI
Once you have connected the IPMI-configured serial port to the SVx41HDI and enabled the
software option, you can begin to configure IPMI settings through the Web interface.
Log in to the Web interface as admin. Click the Admin/Setup link at the top of the page and
choose IPMI/IPMB setup (Intelligent Platform Management).
You will be presented with the IPMI Status menu (see above). Make the following changes to
enable IPMI:
•

allows for multiple levels of security for the BMC, ensure the password you enter on the menu
offers sufficient authority to control chassis power and monitor fan status.
Once you have made the necessary changes on this screen, click Commit to activate IPMI with
the settings you entered. Note that clicking Commit will cause any active VNC sessions to fail
and you will need to re-establish them.
Accessing the Status Screen
The SVx41HDI allows you to monitor the status of the managed computer via IPMI using either
the Web interface or the VNC client. The information you will be able to view using the status
screen will depend on the model of managed computer. Since IPMI implementations vary
widely across manufacturers, the information you are able to see on your status screen may differ
from the examples. Note that the Status screen will not allow you to make any configuration
changes and is for monitoring purposes only.
To access the Status (IPMI Sensor Report) screen:

SVx41HDI Series Server Remote Control: Instruction Guide
Appendix E: The Modem Option Upgrade
Background
The modem option allows the SVx41HDI to act as an Internet connection server for increased
security and flexibility in connecting with the managed computers. Unlike the TCP/IP
connection used with the standard Web configuration and VNC clients, the modem creates a
one-to-one connection between the SVx41HDI and the computer you are using to manage your
network that is essentially private, as it bypasses the public Internet completely. Note this option
requires both an external modem (most standard connection protocols are supported) and a
dedicated phone line that can be connected to the modem for external access. While it is
technically possible to use the modem feature through some PBX systems, this increases the
complexity and reduces the performance of the connection. For clarity, the instructions
presented here assume that the modem is connected to a typical POTS (plain old telephone
system) line that is not routed through a phone management system or shared with other devices.
If you wish to use this feature through a PBX system, it may require some experimentation and
additional support from your telecom services provider, and is not supported by StarTech.com.
Activating the Modem Option
A system without the modem option enabled
The SVx41HDI contains the necessary hardware to attach a modem. To enable the modem
capability, you must purchase the software option from StarTech.com unless you have purchased
a model with the feature pre-enabled. To verify whether the modem feature is enabled on your
unit, login to the Web interface as Admin, click the Setup/Admin button at the top of the page,
and click Firmware and flash memory management. If MODEM is not listed beside
Software Options (see above) then the modem option is not present and you will have to
purchase the software option to use the feature.

SVx41HDI Series Server Remote Control: Instruction Guide
Have your model and serial number on hand. When asked, supply the technician with the code
listed under Purchase Options at the bottom of the Firmware and flash memory management
page. Once the order is processed, the technician will provide you with an Unlock code. Enter
that code in the space provided, and click Submit. The system will update itself to allow modem
configuration.
Connecting a Modem
The SVx41HDI will work with virtually any Hayes-compatible modem that recognizes the
standard AT command set. Some modem manufacturers offer “enterprise” grade modem
products (at a premium price) that include technology to improve the stability of connections;
whether this type of product would be beneficial to your application depends on whether you
consider the modem connection to be mission-critical, the quality of your telecom infrastructure,
and your budget for implementing this solution. The model of modem attached is essentially
transparent to the SVx41HDI.
It is important to note that modems that offer “56K” (or 56,000 bps) connections often achieve
connection speeds that are far lower than their maximum capabilities. Given the limitations of
telecom infrastructure (many locations have yet to implement fully digital switching technology,
and still rely on older analog technology for some segments), the maximum “upstream” transfer
rate is limited to a maximum of 33,600 bps between two modems; the “downstream” rate is often
within a similar range for a typical connection. Therefore, speeds below 56,000 bps do not
indicate a problem with the modem or the SVx41HDI but simply reflect the line conditions at the
time the connection is made. The SERIAL port on the rear panel must be used for the modem
connection. It requires the use of a null modem serial cable.
Place the modem near the SVx41HDI and an available telephone jack. Connect the modem to
the telephone jack, data cable, and power source according to the instructions in its
documentation. The opposite end of the modem’s data cable should be a DB9 female serial
connection. Connect that end of the cable to the SERIAL connection on the rear panel of the
SVx41HDI.
Configuring a Modem Connection on the SVx41HDI
Most connections will work appropriately with the default settings on the SVx41HDI once the
feature is enabled. When you entered the Unlock code to enable the feature, the SVx41HDI
created a new menu option to enable configuration of this feature.

SVx41HDI Series Server Remote Control: Instruction Guide
Login to the Web interface as Admin. Click Admin/Setup from the top of the page and choose
Modem (PPP) setup.
You will then be presented with the Modem Option menu (see above). Make the following
changes to enable and configure the modem connection.
•
•
•
Enable modem connections (PPP) via serial port/modem: select Enabled.
Baud rate to use (affects connection between us and the modem only): select 115200.
Init string: leave as ATE0S0=1&K3 (see below).
The baud rate dictates the connection speed between the SVx41HDI’s serial port and the modem,
and does not affect the connection speed between the local and remote modems, as they will
negotiate their own connection speed when a connection is made. It is highly recommended that
this setting be left at the default for best performance.
The init string is the command (using the standardized Hayes AT command set) that the
SVx41HDI will send to the modem to activate it. The string included should work with the
majority of modems and configures the following connection properties: answer incoming calls
on the first ring, enable hardware flow control, and lock the connection speed. Your modem’s
documentation will describe other potential init strings that you can use to alter the connection
properties. For instance, you could commit the settings to the modem’s non-volatile memory
(NVRAM) or allow the modem to adjust the connection speed for greater stability (and so on).
You may wish to test the connection with the default init string first before making changes
specific to your modem model or situation to simplify the troubleshooting process.
Click the Commit button to save your changes and activate the modem feature with the specified
settings.

Configuring the Remote Connection
This section describes how to configure a typical Windows dial-up session to access the modem
connection on the SVx41HDI. The instructions here relate to a Windows XP configuration;
other versions of Windows are similar.
1. Open My Network Places from the desktop or the Start menu.
2. Click View network connections.
3. Click Create a new connection under Network Tasks.
4. The New Connection Wizard window will open. Click Next.
5. Select Connect to the Internet and click Next.
6. Select Set up my connection manually and click Next.
7. Select Connect using a dial-up modem and click Next.
8. In the space provided under ISP Name, type an appropriate name of your choosing for
the connection. Click Next.
9. In the space provided under Phone Number enter the phone number for the line to which
the SVx41HDI’s modem is connected. You may need to add the area code, country code,
or other digits needed to access the outside line as appropriate. When finished, click
Next.
10. Make your choice from Anyone’s use or My use only and click Next.
11. Beside User name enter the user name of any valid user created using the Web interface
of the SVx41HDI. Beside Password and Confirm password enter the password that the
user you entered above uses to access the Web interface.
12. This screen also includes 3 checkboxes. Uncheck all 3 checkboxes.
13. Click Next.
14. You may select to add a shortcut to the desktop for this connection. Click Finish.
You can now use this connection to access the SVx41HDI modem. Since you will still login to
the unit through the Web interface after establishing a dial-up connection, the user name on the
PPP connection and the user name used to access the Web interface do not have to be the same.
For security purposes, you may wish to create a separate user name for dial-up access.
The unit will negotiate a PPP connection based on the settings you provided, and no additional
scripting or configuration should be required under most circumstances. This is a summary of
the settings for use with non-Windows operating systems, or other versions of Windows besides
XP:
•
•
PPP (Point-to-Point Protocol) must be used; no other authentication methods are
supported.
TCP/IP must be installed/enabled on the computer making the connection, and must
be used for the dial-up connection.
•
•
•
The connection must be configured to obtain a dynamic IP address.
The user name/password must match a user currently configured on the SVx41HDI.
For best performance and to simplify the troubleshooting process, firewall software
should not be used with the dial-up connection.

SVx41HDI Series Server Remote Control: Instruction Guide
Accessing the Web Interface
Once a dial-up connection has been established, you can access the Web interface or start a VNC
session using the following IP address:
You can now login to the Web interface (and/or VNC session) normally. Note that the remote
machine (the one you dialed from) is automatically assigned the IP address 99.99.99.100 for the
PPP session. This, and the IP address of the SVx41HDI, cannot be modified. The following
TCP/IP port numbers are assigned for a PPP connection, regardless of the settings configured in
the Web interface for the LAN port:
HTTPS: 443
VNC (clear-text): 5900
VNC (SSL secured): 15900
SSH: 22
Performance Notes
•
•
All images over the PPP connection will be grayscale to conserve bandwidth. If other
users are connected while a PPP session is active, their screens will be in grayscale as
well. When PPP in inactive, color is automatically re-enabled.
Some areas of the screen may not be updated as frequently as others, and animations
or other auto-updating areas of the screen may appear out-of-focus or “blocky” as a
result. Since the area around the mouse pointer is refreshed most frequently, hold the
pointer over an area to improve its clarity.
•
•
It may be beneficial to minimize any unnecessary icons, backgrounds, or other clutter
on the managed computer’s desktop to make the dial-up connection as efficient as
possible.
You will need to disable the modem feature and re-connect the serial port on the
SVx41HDI to the port on a managed computer to use serial configuration.
Troubleshooting Guide
The following messages will appear in the system log on the Status screen in the Web interface
and may help to diagnose problems with the modem configuration.

Appendix F: Using Optional R-Port Devices
Background
The SVx41HDI offers a unique way to expand the functionality of the base product. Using the
integrated R-Port on the rear panel, you can add up to 16 RS-485 serial devices using a
specialized daisy-chain technology. The SVx41HDI includes integrated control functionality
that allows you to monitor and configure serial devices using the interactive Web interface. To
minimize space and infrastructure requirements, the R-Port serial devices use a single cable to
carry both power and the data signal. All configuration settings are stored separately in each
attached device in non-volatile memory so that they will not be lost in the event of a power
outage or disconnection.
Connecting R-Port Devices to the SVx41HDI
The cable for each serial device is similar to a phone cable and uses an RJ-14 connector. For the
first serial device, connect the cable (provided) to the R-Port on the rear panel of the
SVx41HDI. Connect the opposite end to the DATA OUT (or similar) port on the serial device.
Note that some devices may use an integrated cable, so you will not need to make a separate
connection on the serial device. Once you have added the first serial device to the SVx41HDI,
you can connect additional serial devices to the DATA IN (or similar) port on the previous
device in the chain. Once the cabling is attached, the device becomes active after a 15 second
initialization period. For specific information regarding cabling and status indicators for a
specific serial console, refer to the instructions that came with the product.
Configuring/Viewing R-Port Devices through the Web Interface
Once you have one or more R-Port serial devices connected, you will able to configure and
manage them through the Web interface. You may need to modify the default settings on the
SVx41HDI to match your various R-Port devices’ default configuration. Consult the
documentation that came with your R-Port device to determine if you need to modify the default
settings to complete the installation. To be able to configure your serial devices, you must be
logged in as admin. Other users will be able to view which devices are active but cannot
configure them.
Once you are logged in, choose the Admin/Setup option from the menu at the top of the Home
screen in the Web interface. Click External Serial consoles setup and control. You will be
presented with the Serial Consoles Attached menu, and a table with the following headings:
#: You can assign a value (1 ~ 99) to each attached serial device. This does not affect the
configuration or operation of the device in any way, but is simply a means to sort this list
for ease of management.
Name/Description: An identifier for the R-Port device. Like the number assignment, it

SVx41HDI Series Server Remote Control: Instruction Guide
Baud (bps): This is the communication speed for the device, and the setting here must
match the setting on the device itself (see below). All common baud rates between 300
and 115,200 bps are supported.
Mode: Sets the character framing scheme that the SVx41HDI will use with the R-Port
device. You can choose from the following selections:
8N1: Eight bits, no parity, one stop bit (default and most common)
7N1/701/7E1/7M1/7S1: Seven bits, (none/odd/even/mark/space) parity, one stop
bit
8N1/801/8E1/8M1/8S1: Eight bits, (none/odd/even/mark/space) parity, one stop
bit
8N2: Eight bits, no parity, two stop bits
Force DCD: Forces the Carrier Detect signal to be active at all times. Normally, DCD
becomes active when a new user connects and is dropped when the last user disconnects
(a response that is similar to many modems). When active, the device will logout and
reset itself if the carrier signal is lost, increasing security. Note that this may not work
with all devices and could impair proper operation in some circumstances. The default
setting is off.
Console Log: Clicking this link will open a separate Web page that will display the last
200 characters committed to that device’s console log. Note that existing data is
overwritten automatically when the 200 character limit is reached.
(Optional, not shown) IPMI: This is an optional feature that requires the purchase of a
software upgrade on the SVx41HDI. Refer to Appendix D for more information about
purchasing and using the IPMI upgrade. This feature will not appear on the menu if the
upgrade is not installed.
You can make as many changes a needed on this menu at one time before applying your
changes. Once you are satisfied with the changes you have made, click Commit changes to
apply the new settings. Click Refresh at any time to see an updated list of attached R-Port
devices.
Advanced Configuration Using the Integrated SSH Shell
In most cases, configuring the SVx41HDI to the same settings as the R-Port devices you are
connecting should allow the devices to work with a minimum amount of configuration.
However, you can also change the default settings on each R-Port device to fit your preferences
and the needs of your application.
If you click the Connect… button next to the device you want to configure, two new windows
will appear. The smaller of the two is a login screen; the other is a SSH terminal window. Click
the login window and sign in as admin (using the same password as the Web interface) to
activate the terminal window. You will see a welcome banner similar to the following:

Baud rate: 115200 bps, 8N1
Connected to #1: (none)... (Press Ctrl-Shift-_ for menu).
You are now connected to the R-Port device. Commands you type will be echoed on the
terminal screen. It offers a simple menu system that allows you to change its configuration
settings. To access the menu press [Ctrl] - [Shift] – [_] (underscore) on the keyboard to access
the menu. It will be similar to the following:
RS-232 Menu (#1: (none), 115200 bps, 8N1)
Q – Disconnect
# - Send break
H – Hangup line (drop DCD)
E – Send Ctrl-Shift-_
L – Low log entries (line buffer)
1 – Show last 10 log entries
other – Return to connection
Press key ->
To execute the desired command, simply press the corresponding key on the keyboard. You can
also execute the command and avoid the menu by pressing the [Ctrl] – [Shift] – [_] key
combination quickly and pressing the letter of the command. To quit the menu, press [Q] on the
keyboard when the menu is active.
Remote Login via SSH
You can also use a standard SSH client to access the R-Port options if you wish to avoid using
the Java-based SSH client in the Web interface. Simply use your SSH client (several freeware
packages are available for download, along with commercial applications) and connect to the IP
address of the SVx41HDI using port 22 (default).
Login in to the SSH session as admin using the same password as the Web interface. At the
command prompt type connect x (where x is the number of the R-Port device you wish to
manage). Alternatively, you can enter the command connect -l to see a list of active devices.
Operating Notes
•
•
Hardware handshaking (CTS/RTS) is required for speeds exceeding 9600 bps. It is enabled
by default on the SVx41HDI, but may need to be enabled on the other end of the connection.
For Unix systems, the command is:
stty –crtscts < /dev/[serial port]
R-Port devices use a simple RS-485 multidrop network running at 115,200 bps. It is possible
that every R-Port device will not be inputting/outputting data at the same rate at all time.
However, since these devices use interactive logins, it is unlikely that all channels would be
busy at any one time. Hardware handshaking is used to limit the output rate of individual
channels as needed.
•
A maximum of four users may simultaneously login to the same device. All users may type
commands at any time, and all users will see the same output. Note the following:
• All users have equal access to all channels.
• A maximum of 16 R-Port devices may be connected at any one
time.

•
You plug-in and unplug any R-Port device at any time. When reconnected, it will
automatically become available after a 15 second initialization period. Any log entries will
be retained by the R-Port device while deactivated, but will not be available to users until it is
re-initialized.
