4. Compare the level of software that you noted from the show version command to the
latest level of available software. If the two software levels do not match, download the
latest level from the Web and install it on your switch.
Upgrading the switch software
Switch software is upgraded through a TFTP server application. Typically, this software runs
as an application under your operating system. Make sure that the software is installed on
your server, then download the software images from the IBM Web site 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 must establish a
Telnet session through the Management Module. To make sure you have a connection, ping
the TFTP server. 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. Use the Management Module graphical interface to configure the IP
addresses of the Management Module external network interface (eth0) and the Cisco
Systems Intelligent Gigabit Ethernet Switch Module so that they are on the same subnet as
the TFTP server.
Installing a TFTP server
In this section, we show how to transfer firmware to the Cisco Systems Intelligent Gigabit
Ethernet Switch Module. Note that we are not recommending the use of any particular TFTP
product because several good products are available on the World Wide Web. However, to
demonstrate our example, we used SolarWinds TFTP. The TFTP Server from SolarWinds
runs on these Microsoft operating systems: Windows 95, 98, NT, ME, 2000, and XP.
We obtained SolarWinds TFTP from the following Web site:

Click TRY NOW and fill out the form on the page. Execute the downloaded file to install the
code, and reboot the machine. The default configuration does not allow files to be transmitted
from the installed machine. Configure SolarWinds by performing the following steps:
1. Click File
→ Configure (Figure 6-6).
