Upgrading the switch firmware
You can upgrade the switch firmware by using a TFTP server application.
Typically, this firmware runs as an application under your operating system. Make
sure that this firmware is installed on your server; then, download the firmware
images from http://www.ibm.com/systems/support/ into a directory on your
TFTP server. Enable the TFTP server and set its default directory to the one where
the image is.
To transfer the firmware image files from the TFTP server to the switch, you can
establish a Telnet session through the management module. Ping the TFTP server
to make sure that you have a connection. The Telnet session performs optimally if
all three network entities (TFTP 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 TFTP server.
Examples of IP addresses and masks are described in the following table.
Network entity IP address Mask
TFTP 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 TFTP server.
Access the switch command line interface (CLI). Refer to “Configuring the switch
through the Telnet interface” on page 20 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 zzzzz
where
imagex
is the image to install 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. Press Enter for user name.
5. Enter data path (either mgt or data ).
6. Reset and restart the switch as described in “Resetting and restarting the
switch.”
Resetting and restarting the switch
To activate the new image or images, you must reset the switch. To reset the
switch, complete the following steps:
