Caution To prevent ESD damage, handle DIMMs by the card edges only. Place removed DIMMs on an antistatic mat and store them in an antistatic bag.

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

SDRAM DIMM.

Removing SDRAM DIMMs

Use the following procedure to remove the existing DIMMs:

Step 1 Turn off the system power and remove the VIP4 from the system. (Follow the steps in the “Removing a VIP4” section on page 18 .)

Step 2 Place the VIP4 on an antistatic mat or pad and ensure that you are wearing an antistatic device, such as a wrist strap.

Position the VIP4 so that the handles are away from you and the bus connectors are toward you—opposite of the position shown in Figure 4.

Step 3 Locate the DIMM and position the VIP4 so that you are facing the DIMM module you want to remove.

Step 4 Open the DIMM socket tabs on the DIMM to release the DIMM from the socket. (See Figure 5.) The DIMM is under tension in the socket; therefore, the DIMM might be released from the socket with some force.
