This system is designed to be user maintainable. If diagnostic tests identify a faulty part, you must order a replacement part, remove the faulty part, and install a replacement part. Contact your service organization before removing the faulty part.
This chapter tells you how to replace the following parts:
graphics board set
CPU module
power supply
SIMM modules
internal drives
CPU baseboard
keyboard or mouse
external SCSI drives
If diagnostics have identified a faulty part, remove the faulty part, then follow these steps to order a replacement:
Copy the “Part Request Form” directly from the last page of this guide.
Note the name of the faulty part on the copy of the form.
Note the serial number of your system. The number is on a label on the back of the system.
Identify the part number of the faulty part.
Contact your service provider for further instructions.
Your service provider will ask you for the system serial number, configuration information, the faulty part's part number, and a description of the problem.
Pack and ship the faulty part to your service provider if requested.
For maximum protection to the part, use two sturdy boxes for shipping. Graphics boards, CPU modules and SIMM modules are extremely sensitive to static electricity. Whenever possible, package them in antistatic bags.
Place the faulty part and “Part Request Form” into one of the two boxes. Pack them in plenty of packing material so the part won't sustain further damage. Tape the box securely.
Place the box containing the faulty part into a larger box and fill the empty space with packing materials. Tape the box securely and affix a mailing label. Ship the box to your service provider.
Internal replacement parts include the graphics board, CPU module, power supply, SIMM modules, internal drives, and CPU baseboard.
