Cisco Cisco Fiber IGESM Switch Module for IBM Release Notes

Before downloading software, read this section for important information. This section describes these 
procedures for downloading software:

When you upgrade a switch, the switch continues to operate while the new software is copied to flash 
memory. If flash memory has enough space, the new image is copied to the selected switch but does not 
replace the running image until you reboot the switch. If a failure occurs during the copy process, you 
can still reboot your switch by using the old image. If flash memory does not have enough space for two 
images, the new image is copied over the existing one. Features provided by the new software are not 
available until you reload the switch.

If a failure occurs while copying a new image to the switch, and the old image has already been deleted, 
see the “Recovering from Corrupted Software” section in the “Troubleshooting” chapter of the software 
configuration guide for this release.

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, and there are no other images on the switch, see 
the “Troubleshooting” chapter in the software configuration guide for detailed recovery procedures.

The image is stored as a bin file in a directory that is named with the Cisco IOS release. A subdirectory 
contains the files needed for web management. The image is stored on the system board flash device 
(flash:).

You can use the show version user EXEC command to see the software version that is running on your 
switch. In the display, check the line that begins with 

. This line shows the 

directory name in flash memory where the image is stored.

Although the show version output always shows the software version running on the switch, the model 
name shown at the end of this display is the factory configuration and does not change if you upgrade 
the software image.

You can also use the dir filesystem: privileged EXEC command to see the directory names of other 
software images that you might have stored in flash memory.
