Power Supply
The Switch 8800 power supplies are installed at the bottom of the chassis, in the
front. Only one AC power supply is required for each Switch 8800 chassis,
although 2 power supply slots are provided to implement 1+1 redundancy.
The 7-slot chassis uses a 1200 W auto-ranging power supply (3C17506).
The 10- and 14-slot chassis use a 2000 W auto-ranging power supply (3C17507).
When this power supply is used at 110 V, it delivers 1200 W of power, when used
at 220 V, it delivers 2000 W of power.
Do not combine 1200 W and 2000 W power supplies in the same chassis. If you
have two power supplies in your Switch 8800 chassis, they must be of the same
type.
Figure 7 illustrates the 1200 W power supply for the Switch 8800.

Installing Cabling
This section describes how to install and bind cables for your Switch 8800.
Bench-Mounted Switch If you have installed your chassis on a bench, all interface cables run on the left
side of the chassis in the cabling channel, and the chassis power cords run by the
rear chassis panel.
Rack-Mounted Switch If you have installed your switch in a 19-inch standard rack, the cables are bound
on the cable binding rack at the left side of the chassis and arranged to run on the
cable rack or under a raised floor. Collect all the transit data signal cable
connectors and locate them on the floor of the chassis. Power cords run out of the
rear left of the chassis and on a cable rack or under a raised floor.
Cable Binding Keep the following precautions in mind as you bind cables:
■
Do not allow cables to twist or bend as you bind them.
■
The cable body cannot be bent at an angle that is more than twice its diameter.
The cable running out of a connector cannot be bent more than five times its
diameter.
■
Different types of cables (power cord, signal cable, and ground wire) should
not be bound together in a rack. Although different types of cable may cross
over each other, they must not be bound together where they cross. For
parallel cabling, the space between a power cord and a signal cable should be
no less than 30 mm (1.25 in).
■
■
The cable binding rack and cable channel inside and outside a rack should be
smooth.
The hole through which a cable runs through should be smooth or have a
rubber grommet.
■
■
Use plastic cabling ties to bind the cables.
Bind cables before bending them. Ensure that no tie binds the bent part of any
cables to prevent the core of the cable from breaking.
■
■
Do not tie power cables to the guides of any mobile components.
For the cable terminals fixed with screws, the screws or nuts should be
fastened securely.
■
Do not use tapping screws to fasten the cabling terminals.

Upgrading Software The Xmodem protocol transmits files through serial ports and supports both
Using Xmodem 128-byte and 1K-byte packets. Xmodem also supports two types of check; normal
checksum and CRC. When there is a packet error, retransmission is supported,
normally 10 times.
The Xmodem protocol completes transmission by receiving and sending programs.
The receiving program first sends the negotiating characters to negotiate the
check means. After passing the negotiation, the sending program begins to send
the packet.
The receiving program checks the packet according to the negotiated means after
receiving a complete packet. The acknowledgement characters are sent after
passing the check and then the sending program continues to send the next
packet. If the check fails, negative characters are sent and the sending program
sends the packet again.

Upgrading Software TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that is used
Using TFTP without complex interaction between clients and servers.
The client initiates a TFTP transmission. To download files, the client sends a read
request packet to the TFTP server, receives the packet from the server, and sends
the acknowledgement to the server. To upload files, the client sends a write
request packet to the TFTP server, sends the data packet to the server, and receives
the acknowledgement from the server.
The Switch 8800 provides the functions of the TFTP client.
A TFTP Server program is shipped on the CDROM with the Switch 8800.
Before you upgrade:
■
Verify that there is a connection between the TFTP server and the Switch 8800
(use the pingcommand.)
■
Verify that the TFTP server is set up according to the manufacturer's instructions
and that it is enabled and pointing to the correct directory.
To upgrade using TFTP:
1 Verify that you are logged in with super-user privileges.
2 From the Switch 8800 command line (in user view), TFTP the image file from the
TFTP server to the Switch 8800 using the following command:
tftp <TFTP Server IP Address> get <Source File/image>< Dest
File-Optional>
3 Set the boot parameters to specify the file to boot the system from, using the
following command:
boot boot-loader filename
4 Reboot the system.
The following example illustrates this procedure:
<SW8800>tftp 192.168.25.210 get 88003.app
Transfer file in binary mode.
Now begin to download file from remote tftp server, please wait...
/
TFTP: 5690749 bytes received in 376 second(s).
File downloaded successfully.

Managing Software
Backup
The Switch 8800 uses the application and configuration files it finds on the Flash
of the Fabric from which it booted the previous time. To back up these files, you
can copy them from Flash to compact Flash. However, there are some important
things to know before you copy files to compact Flash:
■
If the Switch 8800 has two Fabrics installed, and you execute a save
command, it synchronizes the configuration file on the Flash on both Fabrics so
that both Fabrics can use the same configuration information.
■
The Switch 8800 does not synchronize versions of the application file between
Fabrics. Therefore, you must manually download the application file to one
Fabric, then copy the application file between Flashes to insure that both
Fabrics can boot from the same file.
■
■
■
To insure that both Fabrics boot the same way, you must configure boot
parameters with the same values on each Fabric.
The system does not synchronize files between compact Flash cards or
between compact Flash and Flash.
For compact Flash to serve as a reliable file backup, you must take care that
files are copied to compact Flash after every modification or download.
Otherwise, you could have multiple versions of a file on your system.
To verify the names and contents of the Flash and compact Flash on your system,
you can use the dircommands, as shown in the following examples:
<SW8800>dir ?
/all
List all files
STRING<1-136> [drive][path][file name]
