Cisco Cisco IOS Software Release 12.4(22)XR

In SAMI cards with Cisco PDSN Release 4.0, erase the existing configuration on all 
processors and reload Cisco PDSN. If the blade includes Cisco PDSN members as part 
of the cluster, we recommend that you remove the PDSN member part before reloading.

Configure the IOMEM size on all processors as 256 MB and save the configuration to 
the NVRAM. 

If you have set the IOMEM size as 64 MB, ensure that you configure the memory 
lite command. The recommended memory size is, however, 256 MB.

Upgrade to Cisco PDSN Release 5.5 and reconfigure the PDSN on processor 3. 

You can configure the Cisco PDSN as both controller and collocated member. Cisco 
PDSN Release 5.5 interoperates with Cisco PDSN Release 3.0 or 4.0 controller or 
member.

Provision MS and PCFs to use the newly added Cisco PDSN Release 5.5-based PDSN 
IP.

Use the CDMA-1x IP address on the PDSN as controller or member IP when 
provisioning.

Provision newly added PDSN with that of the HA to service MIP calls. 

To minimize provisioning tasks, Cisco PDSN Release 5.5 reuses the IP address and routing 
scheme used in one of the Cisco PDSN Release 4.0 processors.
