Powering Up the Hub and Running POST
Powering Up the Hub and Running POST
Before installing and cabling the hub, you might want power up the hub and verify that it
is operational.
To power up the hub, connect one end of the AC power cord to the AC power connector on
the hub and the other end of the cord to a power outlet. If your configuration has a Cisco
RPS, see the RPS documentation.
The hub begins the power-on self-test (POST) after power up. POST consists of the
ten individual tests listed in Table 4-2. The port LEDs show which test the hub is executing.
At power up, all port LEDs are green. As each POST test executes, a port LED turns off.
For example, if the LED for port 12x is off, the boot code test (test 1) is being executed. On
the hub, the port LED for port 12x turns off first, followed by ports 11x, 10x, 9x, and so on.
The LEDs for ports 1x and 2x are not used during POST. The SYSTEM LED is blinking
green while POST is executing.
When POST completes, the following conditions can exist (if other devices are not
connected to the hub):
• All POST tests passed—If the SYSTEM LED is green and all of the port LEDs are off,
no problems were detected. The hub is fully operational.
• Nonfatal failure(s) detected—If the SYSTEM LED is amber and the hub is functional,
POST detected one or more nonfatal failures. Although the hub is still operational and
can forward packets, it might not operate optimally. Refer to the POST failure message
displayed on the diagnostic console screen, identifying the nonfatal failure(s) detected
(see the “Understanding POST Results” section on page 4-4).
• Fatal failure(s) detected—POST completes all tests, even after detecting a fatal failure.
If the SYSTEM LED is amber and one or more of the port LEDs are amber, POST
detected one or more fatal failures. The hub is not operational, but the amber port
LED(s) indicate which test(s) failed.
You should inform your system administrator if one or more nonfatal failures are detected.
Contact your Cisco representative or reseller for support if any fatal failures are detected.
The “Understanding POST Results” section on page 4-4 provides additional information,
including the possible causes of nonfatal and fatal failures.

Connecting to the 10/100 Network Ports and Uplink Port
Connecting to the 10/100 Network Ports and Uplink Port
You can connect the 10/100 network ports and the uplink port to the ports on any 10BaseT
or 100BaseTX network device, such as workstations, servers, switches, routers, and other
hubs.
The 10/100 network ports (ports 1x through 12x or 1x through 24x) are internally crossed.
These ports require a crossover cable to connect to another hub or switch (unless you are
connecting to the uplink port on another FastHub or device). When connecting to a
workstation, server, or router, these ports require a straight-through cable.
The 10/100 uplink port (port 12 or 24) is not internally crossed and requires a
straight-through cable to connect to a server, hub, switch, or router.
By default, each 10/100 port on the hub configures itself to operate at the speed of the port
to which it is connected. If the port on the attached device does not support autonegotiation,
you can explicitly set the 10/100 port to match the speed of the attached port by using one
of the management interfaces available to the FastHub 400M models.
When connecting other network devices to the 10/100 ports, keep the following guidelines
in mind:
• Use the following types of twisted-pair cables when connecting the 10/100 network
ports or the 10/100 uplink port to a network device:
— 10BaseT network devices—Category 3, 4, or 5
— 100BaseTX network devices—Category 5
Note Although you can use Category 3 and 4 cables for 10BaseT networks, these cable
types will not work for 100BaseTX network devices. When designing a network that
includes autosensing repeaters like the FastHub 400 models, keep in mind that
100BaseTX traffic cannot be sent over these cable types.
• Use a straight-through cable to connect two ports when one of the ports is designated
with an X. Use a crossover cable to connect two ports when both ports are designated
with an X.
2-18

Connecting to the 10/100 Network Ports and Uplink Port
• Connecting to devices that do not autonegotiate or that have their speed setting manually
set can reduce performance or result in no link. To maximize performance, choose one
of these methods for configuring the 10/100 ports:
— Let both ports autonegotiate port speed.
— Manually set the same speed setting for the ports on both ends of the connection.
• When a 10/100 device connected to the hub changes speeds (from 10 to 100 Mbps or
from 100 to 10 Mbps), the device must reboot. The device then drops the link to the hub
and recreates the link after rebooting. (If the device does not reboot after changing
speeds, the hub does not detect the change in speed.)
Caution If you connect to ports 12x and 12 (or ports 24x and 24), you will disable both
ports.
Follow these steps to connect to 10BaseT or 100BaseTX devices:
Step 1
Connect one end of the Ethernet cable to a 10/100 port on the hub, as shown in
Figure 2-9.
Note When connecting the hub to workstations, servers, and routers, ensure
that the cable is a straight-through, twisted-pair cable. When connecting the hub
to switches or repeaters, use a crossover cable.

If the port LED does not come on, check for the following problems:
• The network device is not turned on.
• The Ethernet adapter in the network device is not operating correctly.
• You are using the wrong type of Ethernet cable.
• The Ethernet cable is damaged or not connected correctly.
If required, reconfigure and reboot the connected network device.
Repeat Steps 1 through 3 for each device that you are connecting to the hub.

Accessing the FastHub 400 Series Hub Manager
Accessing the FastHub 400 Series Hub Manager
To access the hub manager, all you need is the IP information of the hub (and the password
if one has been assigned). IP information for the hub is usually assigned when the hub is
first started up after installation. (See the “Assigning IP Information to the Hub (FastHub
400M Models)” section on page 2-16.)
Note You can access the hub manager from a PC connected to one of the 10/100 ports.
Therefore, make sure that you do not disable or otherwise misconfigure the port through
which you are communicating with the hub. You might want to write down the port number
to which you are connected. Make changes to the hub IP information with care.
To access the hub manager, follow these steps:
Step 1
Start Netscape Communicator (4.03 or higher) or Microsoft Internet Explorer
(4.01 or higher).
Step 2
Ensure that the following browser features are enabled:
• Java
• JavaScript
• Set the caching of pages to Every time in Communicator or
Every visit to the page in Internet Explorer.
Step 3

Shows when another hub is connected to a
stacking connector on the hub rear panel.
Note You can bookmark the hub IP address to retrieve the hub manager for later use. If
you are using Communicator, choose the Communicator menu option, and select
Bookmarks > Add Bookmark. If you are using Internet Explorer, choose the Favorites
menu option, and select Add to Favorites. Do not use the right mouse button to bookmark
the hub IP address; doing so only saves the specific frame (image) of the hub manager page.

Accessing the CLI
Accessing the CLI
You can access the CLI
• From a console terminal connected to the hub console port. For more information, see
the “Connecting to the Console Port (FastHub 400M Models)” section on page 2-14.
• Through a Telnet session from a remote host by entering the telnet command and the
name or IP address of the hub.
• Through a Telnet session by clicking Telnet on the hub manager Home Page.
When you access the CLI and a password has been defined, the following prompt is
displayed:
Cisco Systems Console
Enter Password:
Enter the password. The hostname> prompt is displayed after you enter the correct
password.
For complete information about the CLI, refer to the FastHub 400 10/100 Series Command
Reference.
Accessing the MIB Files through SNMP
You can access the hub MIB files through SNMP. The following MIB files contain variables
that can be set or read to provide information about the hub and the traps generated by the
hub.
• RFC1213-MIB.my contains the MIB II (RFC 1213).
• ETHERLIKE-MIB.my contains the Ethernet Transmission MIB (RFC 1643).
• CISCO-CDP-MIB.my contains the CDP MIB.
• SNMP-REPEATER-MIB.my contains the standard MIB for managing the hub.
• RMON-MIB.my contains the RFC 1757 RMON (Groups 1, 2, 3, and 9). More
information about RMON and the RMON groups is provided in the “Remote
Monitoring” section on page 2-25.
• CISCO-SIBU-SIMPLE-UPGRADE-MIB.my contains the MIB module for upgrading
the firmware on Cisco low-end devices.

Accessing the Management Interfaces (FastHub 400M Models)
• CISCO-SIBU-MANAGERS-MIB.my contains the MIB module for management
interfaces on the FastHub 400M models.
• CISCO-SIBU-STACKABLE-DUAL-SPEED-HUB-MIB.my contains the MIB module
that extends the REPEATER-MIB to manage Cisco low-end stackable repeater
products.
If you are going to manage the hub by using SNMP and the MIB files, the Read and Write
community strings need to be set. To do this, you can either
• Use the default community strings
— Read community string. The default is public.
— Write community string. The default is private.
• Assign community strings by using the SNMP Management Page or by using the
snmp-server community command on the CLI.
Note Wait approximately 30 seconds for the changes to be saved to permanent storage
before turning off the hub, or the changes might not be saved.
You can obtain a copy of the MIB files in the following ways:
• Using File Transfer Protocol (FTP) to access the ftp.cisco.com server.
• Using Cisco Connection Online (CCO) to access the cisco.com server.
Using FTP to Access the MIB Files
To obtain a MIB file, follow these steps:
Step 1
Step 2
Step 3
Step 4
Step 5
Use FTP to access the server ftp.cisco.com.
Log in with the username anonymous.
Enter your e-mail name when prompted for the password.
At the ftp> prompt, change directories to /pub/MIBs.
Use the get README command to display the readme file listing available
files.
Step 6
Use the get MIB_filename command to get a copy of the MIB file.

Using CCO to Access the MIB Files
To access the MIB files from CCO, click Software & Support to display the Software
Center site.
CCO serves a wide variety of users through two interfaces that are updated and enhanced
simultaneously: a character-based version and a multimedia version that resides on the
World Wide Web (WWW). The character-based CCO supports Zmodem, Kermit,
Xmodem, FTP, and Internet e-mail, and it is excellent for quick access to information over
lower bandwidths. The WWW version of CCO provides richly formatted documents with
photographs, figures, graphics, and video, as well as hyperlinks to related information.
You can access CCO in the following ways:
• Telnet: cco.cisco.com
• Modem: From North America, 408 526-8070; from Europe, 33 1 64 46 40 82. Use the
following terminal settings: VT100 emulation; data bits: 8; parity: none; stop bits: 1;
and connection rates up to 28.8 kbps.
For a copy of CCO’s Frequently Asked Questions (FAQ), contact [email protected]. For
additional information, contact [email protected].
Remote Monitoring
The Remote Monitoring (RMON) MIB is used by network managers to monitor remote
devices. An RMON implementation consists of a software probe that continually collects
statistics about a LAN and a management station that communicates with the probe. The
probe transfers information to the management station on request or when a predefined
threshold is crossed.
The hub supports four RMON groups (Table 2-1) as defined in RFC 1757. Default statistic
rows are created for each port when you start the hub. You can obtain information about the
four supported groups by using any SNMP management application.

Table 2-1
RMON Groups and Their Functions
Description
Group Name
Statistics
This group collects traffic and error statistics for a specific interface. For
example, you could use this group to determine how many error packets have
been seen on a given port.
Statistics from this group can be used by the history group to record historical
views of network performance. A statistics row is established by default for
each hub port.
History
Alarm
This group periodically samples the counters generated by the statistics
group. This information can be used to establish baseline information
regarding network activity. You can define the intervals you want to record
information for, and you can define how many of the samples are to be stored.
Note RMON statistics gathering has a maximum limit of 50 history buckets
per historyControlTable entry.
This group generates alarms according to user-defined thresholds. You could,
for example, configure RMON to generate an alarm when alignment errors on
a port exceeded a predefined limit. Rising and falling thresholds can be
defined, and the events group can generate traps and automated responses
based on the alarms.
Event
This group sends traps to the management station based on information
(alarms) received from the alarm group.
Where to Go Next
Now that you have installed the hub and, if you have a FastHub 400M models, assigned IP
information to the hub, you can continue to
• Chapter 3, “Configuring and Monitoring from the Hub Manager” for configuration and
monitoring information. (FastHub 400M models only).
• Appendix C, “FastHub Stacks” for interconnecting the hub to other FastHub 400M
models to form hub stacks.
• Appendix D, “Switched Uplink Modules” for descriptions of the optional switched
uplink modules and procedures for installing and connecting to them.
