Cisco Systems NPE-225 사용자 설명서

This section provides instructions for removing and installing DRAM or SDRAM on a network 
processing engine or network services engine.

This section explains how to remove DRAM SIMMs that are installed on your network processing 
engine. To remove the installed DRAM SIMMs, complete the following steps:

The NPE-175, NPE-225, and NPE-300, and NSE-1 use SDRAM DIMMS. See the 

 for DIMM replacement instructions.

Attach an ESD-preventive wrist strap between you and an unpainted router surface.

Place the network processing engine on an antistatic mat or surface (ensure that you are wearing an 
antistatic device, such as a wrist strap). 

Position the network processing engine or network services engine so that the handle is away from you 
and the edge connector is toward you.

Locate the SIMMs.

For the location of the memory module you are replacing, find the illustration that corresponds to your 
network processing engine in 

SIMMs installed in your system might look different from the SIMMS shown in the following 
illustrations.

Release the spring latches from the SIMM that you want to remove, and release the SIMM from the 
socket. (See 

.) 

Pull the latches away with your thumbs, bracing your forefingers against the posts.

Raise the SIMM to a vertical position.
