Chapter 9 Replacing DRAM on the Route Switch Processor

Upgrading or Replacing DRAM SIMMs on the RSP2

Removing RSP2 SIMMs

This section describes the procedure for removing RSP2 SIMMs.

Caution To prevent ESD damage, handle SIMMs by the card edges only.

Figure 9-2 Releasing the RSP2 SIMM Spring Clips

Step 1 Turn off the system power and remove the RSP2. (If you have a Cisco 7507 or Cisco 7507-MX, see the

procedure in Figure 3-8; if you have a Cisco 7513, Cisco 7513-MX, or a Cisco 7576, see the procedure

in Figure 3-14.)

Step 2 Place the RSP2 on an antistatic mat or pad, and ensure that you are wearing an antistatic device, such as

a wrist strap. Position the RSP2 so that the faceplate is away from you and the edge connector is toward

you—the opposite of the position shown in Figure 9-1.

Step 3 Locate the DRAM SIMMs on the RSP2. The SIMMs occupy U33 and U21 in bank 0, and U12 and U4

in bank 1.

Step 4 Release the spring clips from the SIMM you want to remove and release the SIMM from the socket. (See

Figure 9-2.)

Step 5 When both ends of the SIMM are released from the socket, grasp the ends of the SIMM with your thumb

and forefinger and pull the SIMM completely out of the socket. Handle the edges of the SIMM only;

avoid touching the memory module or pins and the metal traces (the metal fingers along the connector

edge of the SIMM) along the socket edge.
