Caution To prevent system and memory problems when you install DRAM, the RSP2 DRAM SIMMS must be

3.3V devices. Do not attempt to install higher-voltage devices in the RSP2 SIMM sockets. Handle the

SIMM by the card edges only, and avoid touching the memory module, pins, or traces (the metal fingers

along the connector edge of the SIMM). (See Figure 13.)

Figure 13 Handling the SIMM

Note Use only SDRAM SIMMs from Cisco Systems. A Cisco manufacturing part number appears on each

SDRAM SIMM.

Removing SIMMs

This section discusses the procedure for removing SIMMs from your RSP2.

Use this procedure to remove the existing SIMMs:

Step 1 Turn off the system power and follow the steps in the “Removing the RSP2” section on page 15.

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.

Step 3 Position the RSP2 so that the faceplate is toward you and the bus connectors are away from you—this

position is shown in Figure 2.

Step 4 Locate the DRAM SIMMs on the RSP2. The SIMMs occupy U33 and U21 (Bank 0) and U12 and U4

(Bank 1). (See Figure 2.)
