Chapter 7

Replacing Parts

3.Remove a DIMM from its protective container, handling the module by its edges. If necessary, lay it on an anti-static surface until you are ready to install it.

4.Align the notches on the DIMM with the keys on the slot.

Figure 7-9. DIMM to Slot Alignment

5.Holding the DIMM at 90 degrees to the system board, press the DIMM fully into the slot until the retaining latches close.

If the latches do not close, the DIMM is not inserted correctly.

6.Repeat Steps 1-5, to install all of the remaining DIMMs for your memory configuration.

7.Replace the left side cover.

8.Replace the external cables and power cord.

9.Power on the Server, as described in Chapter 1, “Controls and Indicators.” If the DIMMs are not seated properly you may get a blank screen.

NOTE

Most DIMMs are dimensionally identical, so, if you have two or more DIMMs installed,

 

you may verify all DIMMs are seated by sliding a straight edge (a pen, for example)

 

across the top edges and verify it remains in continuous contact with all of the DIMMs.

 

 

Processor

Use the procedures in this section to remove and replace the heat sink-cooling fan and the processor.

CAUTION Wear a wrist-strap and use a static-dissipating work surface connected to the chassis when handling components. Ensure the metal of the wrist-strap contacts your skin.

Removing the Heat Sink and Cooling Fan

1.If the Server is operating, power down the Server.

Refer to Chapter 1, “Controls and Indicators” for instructions.

2.Disconnect the power cord and any external cables connected to the Server. If necessary, label each one to expedite re-assembly.
