To upgrade the Supervisor image:

Copy the SUP image to the disks

 

(for example, disk0: / slavedisk0:).

Add the following command to the running-configuration boot system disk0:SUP-image-name. For

Run the write memory command to save the running-configuration on the active and standby SUP.

Run the reload command on the active SUP.

Both active and standby SUP reload simultaneously and come up with the SXE3-based image.

no cdma pdsn redundancy command.

7600a-Stdy(config)# no cdma pdsn redundancy

Run the write memory command to save the configuration.

Make the necessary configuration changes on the standby Cisco PDSN, and save the configuration.

Run the cdma pdsn redundancy command again and save the configuration.

Issue the reload command to bring the standby Cisco PDSN back into the session redundancy setup with 
the changed configuration. Verify if the processor comes back in the SR setup using the following show 
commands:

7600a-Stdy# show standby brief
