1. Bank 1 (U15) must be populated first.
2. One 1-GB DIMM is the default SDRAM configuration for PRP-2.
3. The larger DIMM must be placed in Bank 1 (U15).
Note If your system includes redundant PRPs, both PRPs should have the same memory size. Redundancy is
not supported when using a GRP and a PRP in the same chassis. Cisco strongly recommends that you
avoid configuring your router using mixed route processor cards. Refer to the Route Processor
Redundancy Plus for the Cisco 12000 Series Internet Router publication for more information.
