NRP-1 Memory Description
The default DRAM configuration is 64 MB, contained in two 32-MB SIMMs. The DRAM can be
increased to 128 MB by replacing them with two 64-MB SIMMs. The amount of DRAM required on the
NRP-1 module is determined by the number of routed and bridged sessions the NRP-1 is configured to
handle.
The default Flash configuration is 8 MB, but you can upgrade to a 16-MB Flash SIMM. The amount of
Flash memory required on the NRP-1 module is determined by the number and sizes of images and
configuration files stored in Flash memory.
To upgrade either DRAM or Flash memory on the NRP-1 module, you must purchase an upgrade kit
from Cisco Systems and replace the current SIMMs.
Note You must use SIMMs obtained from Cisco Systems.
Removing an NRP-1 Module SIMM
To remove the SIMM from the Cisco 6400 chassis:
Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
Step 1
Disconnect the signal and control cables from the NRP.
Step 2
Loosen the captive installation screws on the NRP module and remove the module from the chassis.
Step 3
Place the NRP module on an antistatic mat or pad. Position the NRP module so that the faceplate is away
Step 4
from you, and the edge connector is toward you.
Locate the SIMMs on the NRP module
Step 5
Release the spring clips from the SIMM that you wish to remove and lift the SIMM from the socket
Step 6
(Figure
When both ends of the SIMM are released from the socket, use your thumb and forefinger to grasp the
Step 7
ends of the SIMM and pull the SIMM completely out of the socket. Handle the edges of the SIMM only;
avoid touching the memory module, pins, or metal traces (fingers) along the socket edge.
Step 8 Place the SIMM in an antistatic bag to protect it from ESD damage.
