After you install new DIMMs and replace the PRP in the router, the router
reinitializes the PRP and detects the memory change as part of the reinitialization
cycle. The time required for the router to initialize can vary with different router
configurations and memory configurations.
If the PRP or the system does not reinitialize properly after you upgrade memory,
or if the console terminal displays a checksum or memory error, verify the
following:
Check the packet memory DIMMs to verify that the type, size, and speed of the
DIMMs are compatible with the PRP. DIMMs must operate at 60 ns or faster. The
speed of the DIMM is printed along one of its edges.
Ensure that the DIMMs are installed correctly on the PRP. Check the alignment
of the DIMMs by looking at them across the horizontal plane of the card. The
DIMMs should be aligned at the same angle and be fully inserted into their
respective sockets. If a DIMM is not correctly aligned, remove it and reinsert it.
Reinstall the PRP and perform another installation check.
If the router fails to restart properly after several attempts and you are unable to
resolve the problem, access Cisco.com or contact your Cisco service
representative for assistance. Before calling, however, make note of any console
error messages, unusual LED states, or other router indications or behaviors that
might help to resolve the problem.
This section provides information for upgrading the Chopper FPGA on PRP-2
using a CLI interface from RP. The new Chopper FPGA image is bundled into the
FPD package file for the release. This image enables you to upgrade the Chopper
FPGA on PRP-2 without requiring a RMA replacement. The new FPGA image is
versioned v97. It is highly recommended that you perform this upgrade as part of
normal software upgrade procedure.
