Upgrading The Switch-Module Software - IBM BNT Installation Manual

Upgrading the switch-module software

You can upgrade the switch-module software by using a TFTP server application.
Typically, this software runs as an application under your operating system. Make
sure that this software is installed on your server; then, download the software
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 software 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 module 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.
Note: With this configuration, you can ping the switch module from the TFTP
Use the management-module interface to start a Telnet session, as described in the
following steps. The requirements for running a Telnet session are described in
Chapter 6, "Configuring the switch module," on page 27.
1. Log on to the management module as described in the IBM BladeCenter
2. From the I/O Module Tasks menu, click Configuration → Bay X → Advanced
3. To start a Telnet session, click Start Telnet/Web Session.
To upgrade the switch-module software, complete the following steps:
1. Log in to the switch module.
2. At the CLI prompt, type the following command and press Enter.
3. Reset and restart the switch module as described in "Resetting and restarting
4. At the CLI prompt, type the following command and press Enter.
