Cisco Cisco IOS Software Release 12.4(2)XB6

The following sections contain details on how to upgrade your Cisco PDSN:

To upgrade the Supervisor image, perform the following procedure:

Copy the SUP image to the disks (disk0: / slavedisk0:).

Add the following command to the running config boot system disk0: SUP image name. Here is an 
example:

:s72033-advipservicesk9_wan-mz.122-18.SXE3.bin

This step may require you to unconfigure previously configured instances of this CLI in order 
to enable the image to properly reload.

Perform a “write memory” so that running configuration is saved on both active and standby SUP.

Issue reload command on the active SUP.

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

Issuing the reload command on the active SUP will cause both the active and standby 
Supervisors to reload simultaneously, thus causing some downtime during the upgrade process.

To upgrade an image on the Cisco PDSN on the SAMI card, follow the directions located at the following 
URL:

If you need to change the working configuration on a PDSN in a live network environment, perform the 
following procedure:

Bring the standby PDSN out of service. An example would be to unconfigure the cdma pdsn 
redundancy command on the standby PDSN. This isolates the standby PDSN from the session 
redundancy setup.
