RIMMs

CAUTION: Before you remove the computer cover, see "Precautionary Measures."

To remove a Rambus in-line memory module (RIMM), perform the following steps.

CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals, disconnect them from their electrical outlets, and then wait at least 5 seconds before you remove the computer cover.

CAUTION: The RIMMs can get extremely hot during system operation. To avoid dangerous burns, be sure that the RIMMs have had sufficient time to cool before you touch them.

NOTE: Before disconnecting a peripheral from the system or removing a component from the system board, verify that the standby power LED on the system board has turned off. For the location of this LED, see Figure 28.

1.Remove the computer cover according to the instructions in "Computer Cover."

2.Press the securing clips outward simultaneously until the RIMM disengages and pops out slightly from the socket (see Figure 30).
