Removing a 32-bit, 33 MHz Half-Length PCI Add-in Board

WARNING

If the system has been running, any installed PCI add-in board on the processor board(s) will be hot. To avoid the possibility of a burn, be careful when removing or installing baseboard components that are located near processors.

System power on/off: The on/off button on the front panel DOES NOT turn off the system AC power. To remove power from system, you must unplug the AC power cords from the wall outlet or the system.

CAUTION

Slot covers must be installed on all vacant expansion slots. This maintains the electromagnetic emissions characteristics of the system and ensures proper cooling of system components.

The add-in boards for the half-length 33 MHz PCI slots are NOT Hot-Pluggable. In other words, you must turn off the AC power to the system first before installing boards at these locations.

1.Observe the safety and ESD precautions at the beginning of this chapter.

2.Disconnect any cables attached to the PCI board you are removing.

3.Remove and save the screw that attaches the existing board retaining bracket to the chassis.

4.Holding the board by its top edge or upper corners, carefully pull it out. Do not scrape the board against other components.

5.Store board in an antistatic protective wrapper.

6.If you are not reinstalling a board in the same slot, install a slot cover over the vacant slot. The tapered foot of the cover must fit into the mating slot in the expansion slot frame.

7.Use the screw removed earlier to fasten the new board to the chassis. Tighten the screw firmly (6.0 inch-pounds).
