Upgrading the switch firmware
You can upgrade the switch firmware by using a server application. Typically, this
firmware runs as an application under your operating system. Make sure that this
firmware is installed on your file server; then, download the firmware images from
http://www.ibm.com/systems/support/ into a directory on your server. Enable the file
and set its default directory to the directory where the image resides.
Note: If you want your change to persist beyond the next reboot of the switch, you
must type the
copy running-config startup-config
command. This
command stores the current switch configuration and all changes in
nonvolatile memory.
To transfer the firmware image files from the file server to the switch, you can
establish a SSHv2/Telnet session through the management module. Ping the file
server to make sure that you have a connection. The session performs optimally if
all three network entities (file server, management module, and switch IP
addresses) are on the same subnet. Otherwise, you must use a router and
configure a gateway address on the switch. Use the management-module interface
to configure the IP addresses of the management module external interface (eth0)
and the switch so that they are both on the same subnet as the file server.
Examples of IP addresses and masks are described in the following table.
Network entity IP address Mask
File server 192.168.2.178 255.255.255.0
Management module (eth0) 192.168.2.237 255.255.255.0
Switch-module current IP
configuration (IF 128) 192.168.2.51 255.255.255.0
Note: With this configuration, you can ping the switch from the file server.
Access the switch command line interface (CLI). Refer to “Accessing the switch
through the SSHv2/Telnet interface” on page 22 for more information.
To upgrade the switch firmware, complete the following steps.
1. Log in to the switch.
2. At the CLI prompt, type the following command and press Enter.
/boot/gtimg imageX TADDR zzzz
Where
imagex
is the image to install,
TADDR
is the address of TFTP server, and
zzzzz is the operating-system image file name.
3. At the CLI prompt, type the following command and press Enter.
/boot/gtimg boot TADDR yyyy
Where yyyy is the boot image file name.
4. Reset and restart the switch as described in “Resetting and restarting the
switch” on page 27.
