Replacing parts

Replacing parts on the motherboard

Before you remove and replace the DIMMs, CPU, and battery on the motherboard, shut down and open the FC

integrated server (see page 18).

DIMMs

When installing DIMMs, note the following:

• Different capacity DIMMs look alike. Make sure that you know the capacity of each DIMM before you install it in a

socket.

• Install only approved DIMMs available from your service representative.

• DIMMs must be installed in matched pairs. A matched pair is comprised of two alternate sockets (see below).

DIMMs within a pair must be identical (same capacity and same number of chips on each side). For example, in a

two-DIMM configuration, populate DIMM 4 and DIMM 2 with DIMMs of identical capacity, with the same

number of chips on each side.

To replace a DIMM

1 Shut down, and then open the FC integrated server (see page 18).

To access the DIMMs, you must remove the left panel.

2 To release a DIMM, push outward on the levers on each side of the DIMM.

3 Pull the DIMM straight out of the socket.

4 To replace a DIMM, insert the DIMM straight into the socket and close the levers at each side to lock it into place.

Note: The socket is keyed so that the DIMM fits only one way. (See the notches in the preceding figure.)

5 If you installed a new DIMM, make sure to reset the time and date in Windows Control Panel.

6 Reassemble the FC integrated server and verify its functionality (see page 54).

CPU

The CPU is installed in a socket on the motherboard. Before you remove the CPU from its socket, remove the

motherboard from the chassis (see page 26), disconnect the CPU fan cable from the motherboard, and then remove

the cooling assembly from the FC integrated server (see page 34). The CPU cooling assembly consists of a fan and a

heatsink.

Note: Do not remove the CPU fan from the heatsink.

Important: Make sure that the entire length of the DIMM (ends and center) is fully seated in the socket and

that the levers close securely around the ends of the DIMM.
