Replacing an NRP Module
Replacing an NRP-2SV Dual Inline Memory Module
This section describes how to remove and replace an NRP-2SV dual inline memory module (DIMM).
There are two DRAMs on the NRP-2SV module: The control path DIMM and the forwarding path
DIMM.
General DIMM Information
DIMMs are sensitive components that are susceptible to ESD damage. Handle DIMMs by the edges
only; avoid touching the memory modules, pins, or traces (the metal "fingers" along the connector edge
of the DIMM).

Each of these DIMMs is 512 MB. (Older models may have 256 MB. An upgrade kit is available from
Cisco Systems, Inc.) The amount of DRAM required on the NRP-2 module is determined by the number
of routed and bridged sessions the NRP-2 is configured to handle.
There is no Flash memory on the NRP-2SV module.
You must use DIMMs obtained from Cisco Systems.
