Caution!

ESD can damage disk drives, expansion cards, and other components. The server can withstand normal levels of environmental ESD while you hot-swap SCSI hard drives. However, we recommend doing all procedures at an ESD- protected workstation. If one is not available, you can provide some ESD protection by wearing an antistatic wrist strap attached to chassis ground of the server when handling components.

Note:

If the server has less than four processors and you are adding one, then you must remove the termination board assembly from the next Slot 2 connector before you install the new processor. If you plan to reduce the number of processors in your system, then you must replace a processor with a termination board assembly.

Introduction

This chapter provides step-by-step instruction for installing, removing, or replacing several system components. Only authorized service personnel should perform these procedures. Follow all standard safety and ESD precautions when servicing the server. See “Static Electricity Precautions” on page 2 for more information on ESD precautions.

“Opening the System” on page 3 provides detailed instructions for opening the system. All procedures in this chapter assume that any necessary access covers have been removed and that the subchassis and electronics bays have been removed, if necessary.

Replacing the Processor

The system is compatible with Intel Pentium® II Xeon™ processors. You can either upgrade the existing Pentium II Xeon processor or install up to three more processors of the same speed and cache size as the first processor.

When replacing a processor, order a Pentium II Xeon processor upgrade kit. The kit includes the Pentium II Xeon processor, a heat sink, and latches.

It is critical that a heat sink be installed on each processor. The Pentium II Xeon processor overheats and fails if it is not cooled sufficiently. The heat sink provided with the processor in the system provides all necessary cooling for the processor.

For the latest details on the availability of the upgrade kits, contact one of the sources listed in the Assistance Resources document.

To Replace the Processor

1.Turn off the system and disconnect all the power cords.

2.Open the case, observing the static electricity precautions in “Static Electricity Precautions” on page 2 and remove the foam cover on the electronics bay.
