Installing PCI Boards
The information in this section covers installation of optional PCI boards.
Caution: Do not overload baseboard: Do not overload the baseboard by installing
optional PCI boards that draw excessive current. Contact your sales or service
representative if you are uncertain that a board is approved forinstallation in the server.
PCIboardscan be extremelysensitive toESD and alwaysrequirecarefulhandling. After
removing the board from its protective wrapper or from the baseboard, place it
component-side up on a grounded, static-free surface or conductive foam pad—if
available. Do not slide the board over any surface.
Use the following steps to properly install a PCI option board:
1. Remove access cover.
2. Remove the PCI option 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.
3. Record the serial number of the PCI option board in your equipment log.
4. Set jumpers or switches according to the manufacturer’s instructions.
5. Remove and save the screw that attaches the existing board or expansion slot cover
to the chassis.
6. Remove and save the expansion slot cover.
7. Hold the PCI option 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. See Figure 1-3 for an
example.
■ Install an ISA board component-side UP.
■ Install a PCI board component-side DOWN.
8. Use the screw removed earlier to fasten the new board retaining bracket to the
chassis. Tighten the screw firmly (6.0 inch-pounds). Attach cables if necessary.
9. Reinstall the access cover using the original screws.
