This system is designed to be user maintainable. If diagnostic tests identify a faulty part, contact your service organization before removing the faulty part. In some cases you may be instructed to return the system.
This chapter tells you how to:
order a replacement part and package the faulty part for return
replace the system
replace the following internal parts
GIO option board (optional video, network or fast SCSI-2 boards)
graphics board
CPU module
SIMMs (Single Inline Memory Modules)
internal drives (floptical, second hard disk and system disk)
power supply
external SCSI (Small Computer Systems Interface) devices
If diagnostics have identified a faulty part, call your service provider. You will be instructed either to order a replacement part, or to ship the system back. If instructed to return the system, go to “Replacing the System”. If asked to return the part, Figure 8-1 will help you locate the part number of the faulty part.
Follow these steps to order a replacement part:
Contact your service provider.
You will be asked for the system serial number, configuration information, the faulty part's part number, and a description of the problem. You may be instructed to remove the faulty part, or you may be asked to return the entire system.
Make a photocopy of the “Part Request Form” at the back 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.
Remove the faulty part if instructed to do so. Go to the appropriate instructions on replacing parts in this chapter.
Look for the part number of the faulty part; it's shown on the part. (Refer to Figure 8-1.)
Pack and ship the faulty part to your service provider:
If possible, package the part in an antistatic bag. Graphics and GIO option boards, CPU modules, and SIMM modules are extremely sensitive to static electricity.
For maximum protection to the part, use two sturdy boxes for shipping.
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.
If diagnostics have identified a problem with the system, call your service provider. If instructed to return the system, follow these instructions to prepare it for shipping and complete the necessary paperwork.
To preserve your data, remove the disk drives from the system:
Remove the floptical disk drive or second hard disk drive in the top drive slot (if installed). Go to “Replacing the Internal Floptical Drive or Second Hard Disk Drive”.
Remove the system disk drive. Go to “Replacing the System Drive”.
Remove any non-Silicon Graphics memory modules or other non-Silicon Graphics parts installed on the system. Refer to the appropriate section in this chapter to remove the parts.
Remove any external SCSI devices or external parts such as the keyboard, mouse, camera, or monitor. Do not ship these external parts unless told to do so by your service provider.
Make a photocopy of the “Part Request Form” on the last page of this guide.
Complete the “Part Request Form.” You need to know the serial number of your system. The number is on a label on the back of the system. The serial number allows your service provider to identify the correct replacement system for you.
Pack the workstation in the original packing materials that came with it. The workstation should include all the internal parts (except for the system drive) that it shipped with: power supply, system board, CPU module, graphics board, and memory modules.
Note: It's important that you use the original packing materials to prevent further damage to the workstation and its internal parts. If you don't have the original packing materials, contact your service provider.
Ship the workstation to your service provider.
Internal replacement parts include the graphics board, GIO option board, CPU module, SIMM modules, internal drives, and power supply.
Note: Before replacing an internal part, call your service provider for instructions. If the system is under warranty, you may be instructed to ship the system back.

Unwrap the first two folds of the wrist strap and wrap the exposed adhesive side firmly around your wrist.
Unroll the rest of the band and peel the liner from the copper foil at the opposite end.
Attach the copper foil to a metal part of the Indy chassis.
| Caution: The CPU module is extremely sensitive to static electricity. Wearing the wrist strap prevents the discharge of static electricity, which could damage the board. |
Locate the CPU module, as shown in Figure 8-20.
The CPU module is elevated on the system board and is located at the front of the system between the power supply and the system disk drive. It is protected by a textured heat sink. Do not remove the heat sink.
Note: The Indy workstation supports several CPU module shapes. Your system may have a CPU module and heat sink that look different than the one shown below.
Using a Phillips screwdriver, remove the two screws that connect the CPU module to the system board, as shown in Figure 8-21.
Lift the board by bracing your hands against the power supply and the chassis and pushing the board up with your thumbs, as shown in Figure 8-22.
Note: Note that when the board disconnects, it pops up quite quickly and may startle you.
Install the replacement CPU module, as shown in Figure 8-23.
Slide the feet on the bottom of the CPU module into the slippers on the base of the chassis.
Align the two screw holes on the CPU module over the screw holes on the system board.
Seat the connector under the CPU module over the connector on the system board. Make sure it is positioned correctly before going on to the next step.
Press down firmly on the CPU module until it is securely seated in the socket on the system board.
If the connector does not seem to fit into the socket, do not force it. Lift the end of the CPU module slightly and lower it again, making sure it's seated correctly over the connector before pressing it all the way down.
Insert and tighten the two screws you removed earlier to connect the CPU module to the system board. As you tighten the screws, alternate from one to the other so that the board is connected evenly.

Attach the copper foil to a metal part of the Indy chassis.
| Caution: SIMMs and the system's internal components are sensitive to static electricity. Handle the SIMMs carefully, and wear the wrist strap to avoid discharging static electricity. |
Move the system or position yourself so that you are facing the power supply, as shown in Figure 8-24.
Locate the SIMMS between the power supply and the graphics board.There are eight SIMM sockets, split into two banks—0 and 1. Bank 0 is closer to the power supply and contains sockets S1 through S4. Bank 1 is closer to the graphics board and contains sockets S5 through S8.
Locate the memory SIMMs you want to remove. In order to replace a faulty SIMM, you need to remove the SIMM farthest from you first (closest to the graphics board), then remove the other SIMMs until you reach the SIMM you want to replace.
With your thumbs, pull the latches away from the SIMM, as shown in Figure 8-25.
The SIMM releases and tips away from you about 45 degrees.
Note: Some GIO option boards, if installed on the side of the graphics board close to the SIMMs as shown in Figure 8-26, may impede your installation of the SIMM in the last socket of bank 1 (closest to the graphics board). If this is the case, you may have to remove the GIO option board to gain access to the SIMM socket. Turn to“Replacing a GIO Option Board” for instructions and then return to this section.
Remove the other SIMMs the same way.
Install the replacement SIMMs. To install the SIMMs, turn to “Installing SIMMs”.
