Chapter 2. Installing and Removing PCI and XIO Option Boards

This chapter describes how to install PCI option boards in Origin200 and Origin200 GIGAchannel servers, and how to install XIO boards in an Origin200 GIGAchannel server. It also describes how to remove option boards from the respective chassis. This chapter contains the following sections:

Handling Precautions

Option boards are sensitive to electrostatic discharge (ESD). Observe the following precautions when installing and removing memory:

  • Handle the boards by their edges only and do not touch the gold edge-connectors and components on the board.

  • Handle boards with care. Do not toss them roughly onto hard surfaces, such as tables or other equipment. Many boards have fragile, surface-mount components on their undersides; these components can break off with rough handling.

  • Do not leave the option boards loose inside the chassis while you work.

  • When you are not handling them for installation or removal, always keep the option boards in ESD containers, such as conductive bags or foam.

  • Save the ESD bags and containers in which the PCI option was shipped in case you need to remove the board from the system.

Installing a PCI Option Board in an Origin200 and Origin200 GIGAchannel CPU Module

The following steps describe how to install a PCI option board in an Origin200 server. To install a PCI option in a GIGAchannel expansion cabinet, see “Installing a PCI Option Board in a GIGAchannel Expansion Cabinet”.

  1. Prepare the system for servicing as described in Chapter 1, “Preparing the System for Servicing.”

  2. Locate an available PCI option slot. See Figure 2-1.

    Although you can install a PCI board in any open slot, you may observe better I/O performance if you install boards starting in order with slot 5, particularly if the PCI board you are installing can perform prefetching.

    Figure 2-1. Locating the PCI Option Slots

    Figure 2-1 Locating the PCI Option Slots

  3. Remove the blanking plate from the slot.

    • Using a #2 Phillips screwdriver, remove the single screw that secures the blanking plate to the chassis. See Figure 2-2.

    • Remove the blanking plate by lifting it straight up, as shown in Figure 2-2. Save the blanking plate it in case you have to remove this option in the future.

      Figure 2-2 Removing a PCI Slot Blanking Plate

  4. For PCI boards with feature connectors only. Some PCI boards from SGI provide an extra connector for additional signals used for multimedia applications. To install such a board in an Origin200 server, you must install a cable from a connector on the board to the feature connector on the PCI backplane. If you are not sure if the PCI board you are installing uses a feature connector, refer to Figure 2-3.

    Figure 2-3. Example PCI Board With Feature Connectors

    Figure 2-3 Example PCI Board With Feature Connectors

    • Locate the feature-connector cable in the PCI board shipment. See Figure 2-4.

    • Attach either end of the feature-connector cable to the connector next to the desired PCI slot on the Origin200 PCI backplane, as shown in Figure 2-4.

      Figure 2-4. Attaching a Feature Connector Cable to the PCI Backplane

      Figure 2-4 Attaching a Feature Connector Cable to the PCI Backplane

    • Connect the other end of the cable to the Origin200 PCI board feature connector, as shown in Figure 2-5.

      Figure 2-5. Attaching a Feature Connector Cable to the PCI Board

      Figure 2-5 Attaching a Feature Connector Cable to the PCI Board

  5. Install the PCI option board in the PCI slot.

    • Align the connector on the base of the PCI board with the PCI slot, as shown in Figure 2-6.

    • Press the board down into the slot until it engages.

    • Be sure the tab at the bottom of the PCI board plate slides into the slot on the rear chassis wall.

    • Press firmly until the board is seated. You may find that a slight front-to-back rocking motion helps seat the board more easily.

    • Be careful not to kink or damage the flexible EMI gasket that surrounds the inside of the rear chassis wall.

    • If the PCI board uses the feature connector cable, tuck the cable between the board and the adjacent one.

    • Attach the screw that secures the PCI option board to the chassis, as shown in Figure 2-6.

      Figure 2-6. Securing the PCI Option Board to the Chassis

      Figure 2-6 Securing the PCI Option Board to the Chassis

  6. Remove your wrist strap and reassemble the system.

    • Replace the chassis access cover and side panel (the reverse of removing them).

    • Reattach the cables to the back of the system.

Note: Do not discard the blanking plate that you removed from the Origin200 chassis. If you ever decide to remove the PCI option board, you must replace this blanking plate to ensure proper airflow through the Origin200 chassis.

For information about how the board is recognized (detected) by the system and configured, see the Origin200 and Origin200 GIGAchannel Owner's Guide and whatever documentation is provided with your option board.
