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.

1.Remove the computer cover.

2.Press the securing clips outward simultaneously until the RIMM disengages and pops out slightly from the socket (see Figure 24).

To install replacement memory, 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. Also, before you replace memory, see the other precautions in "Precautionary Measures. "

1.Remove the computer cover.

2.If necessary, remove any RIMMs that occupy sockets in which you plan to install the replacement RIMMs.

NOTES: If you are not installing a replacement RIMM at this time, you MUST remove the remaining RIMM in the pair and install a pair of continuity modules (CRIMM).

When operating with a single pair of RIMMs, they MUST occupy sockets RIMMB-1 and RIMMA-2, with CRIMMs installed in RIMMB-3 and RIMMA-4.

3.Install the RIMMs:

a.Locate the plastic securing clips at each end of the socket (see Figure 25).

b.Press the clips outward until they snap open.

c.Press the RIMM straight into the slot running down the center of the socket until the securing tabs snap into place around the ends of the RIMM.
