Cisco Cisco Fiber IGESM Switch Module for IBM Release Notes

 lists the software filenames for this release.

The upgrade procedure in this section describes how to perform the upgrade by using a combined tar file. 
The procedure assumes that you have already downloaded the tar file for this release from ibm.com to 
your TFTP server or management station. The tar file is an archive file from which you can extract files 
by using the archive download-sw command.

For information about where to access the tar files on ibm.com and the names of the tar files for this 
release, see the 

Do not power cycle the switch while you are copying an image to the switch. If a power failure occurs 
while you are copying the software image to the switch, call your technical support representative 
immediately.

The upgrade procedure uses the archive download-sw privileged EXEC command to automatically 
extract and download the images to the switch. The archive download-sw command automatically 
deletes the old version and copies the new version to flash memory if the flash memory does not have 
space to store the old and new versions simultaneously. The archive download-sw command initiates 
this process:

It verifies adequate space on the flash memory before downloading the new image.

If there is insufficient space on the flash memory to hold both the old and the new images, it deletes 
the old image. The image is always stored in a subdirectory on the flash memory. The subdirectory 
name is the same as the image release name, for example cigesm-i6q2l2q4-tar.121-22.EA9.tar.

After the new image is downloaded, it automatically sets the BOOT environment variable. You do 
not have to change the names of old file names to new file names.

If you enter the command with the /reload or the /force-reload option, it automatically reloads the 
switch after the upgrade.

For more information on using these commands, see the command reference for this release.
