4: Removing and Installing User Serviceable Components
88
Note: At this time, the Linux operating system does not support use of the PCI Hot-Plug
(PHP) feature. If you are running Linux, your system must be turned off before installing
or removing PCI boards. Windows 2000 requires drivers that are PHP compatible in
order to use the PHP feature.
1. Observe the safety and ESD precautions at the beginning of this chapter and this
procedure.
2. Release the two thumbscrews located on the top rear of the chassis. One of two
thumbscrews is noted by "A" in Figure 4-6 on page 86.
3. Using an even pull, press lightly on the top cover and slide it back until it stops.
4. Lift the entire top cover upward away from the chassis.
5. Remove add-in board from its protective wrapper. Be careful not to touch the
components or gold edge connectors. Place board component-side up on an
antistatic surface.
6. Record the serial number of the add-in board in your equipment log (see
"Equipment Log" on page 90).
7. Make sure that the slot is powered off. If the slot is powered on, turn the power to
the slot off through the PCI Hot-Plug application on your system or through the
HW push button.
8. Set jumpers or switches on the board according to the manufacturer's instructions.
9. Remove and save the expansion slot cover, if one was present.
10. Hold the add-in board by its top edge or upper corners. Firmly press it into an
expansion slot on the baseboard. The tapered foot of the board-retaining bracket
must fit into the mating slot in the expansion slot frame.
11. Press in the PCI Hot-plug (PHP) retention mechanism toward the back panel. This
action locks the add-in board into place. See Figure 4-4 on page 84.
12. If you are installing a full-length board, lock the rear retention latch. See Figure 4-5
on page 85.
13. Use the screw removed earlier to fasten the new board to the chassis. Tighten the
screw firmly (6.0 inch-pounds).
14. Attach cables if necessary.
15. Power on the add-in board through the PCI Hot-Plug application on your system or
through the HW push button.
