Replacing a PCI riser-card assembly

Use this information to replace a PCI riser-card assembly.

The server provides two PCI riser-card slots on the system board. The following information indicates the riser-card slots:

  • Standard models of the server come with one PCI Express riser-card assembly installed. If you want to replace them with PCI-X riser-card assemblies, you must order the PCI-X riser-card assembly option, which includes the bracket.
  • A PCI Express riser-card assembly has a black connector and supports PCI Express adapters, and a PCI-X riser-card assembly has a white (light in color) connector and supports PCI-X adapters.
  • PCI riser slot 1 (the farthest slot from the power supplies). You must install a PCI riser-card assembly in slot 1 with microprocessor 1.
  • PCI riser slot 2 (the closest slot to the power supplies). You must install a PCI riser-card assembly in slot 2 with microprocessor 2.
  • PCI riser-card brackets must be installed even if you do not install an adapter.

To install a PCI riser-card assembly, complete the following steps:

  1. Read the safety information that begins on Safety and Installation guidelines.
  2. Turn off the server and peripheral devices and disconnect all power cords.
  3. Remove the cover (see Removing the cover).
  4. Reinstall any adapters and reconnect any internal cables you might have removed in other procedures (see Replacing an adapter and Internal cable routing and connectors).
  5. Align the PCI riser-card assembly with the selected PCI connector on the system board:
    1. PCI connector 1: Carefully fit the two alignment slots on the side of the assembly onto the two alignment brackets in the side of the chassis.

    2. PCI connector 2: Carefully align the bottom edge (the contact edge) of the riser-card assembly with the riser-card connector on the system board.
  6. Press down on the assembly. Make sure that the riser-card assembly is fully seated in the riser-card connector on the system board.
  7. Replace the cover (see Replacing the cover).
  8. Slide the server into the rack.
  9. Reconnect the power cords and any cables that you removed.
  10. Turn on the peripheral devices and the server.
