Replacing a PCIe card

To replace a PCIe card, you must remove the cabling and any SFPs from the ports on the PCIe cards in the target riser, remove the riser from the controller module, remove and replace the PCIe card, reinstall the riser, and recable it.


  1. If you are not already grounded, properly ground yourself.
  2. Remove the PCIe riser from the controller module:
    1. Remove any SFP modules that might be in the PCIe cards.
    2. Rotate the module locking latch on the left side of the riser up and toward the fan modules.
      The PCIe riser raises up slightly from the controller module.
    3. Lift the PCIe riser up, shift it toward the fans so that the sheet metal lip on the riser clears the edge of the controller module, lift the riser out of the controller module, and then place it on a stable, flat surface.

  3. Remove the PCIe card from the riser:
    1. Turn the riser so that you can access the PCIe card.
    2. Press the locking bracket on the side of the PCIe riser, and then rotate it to the open position.
    3. Remove the PCIe card from the riser.
  4. Install the PCIe card into the same slot in PCIe riser:
    1. Align the card with the card guide on the riser and the card socket in the riser, and then slide it squarely into the socket in the riser.
      Note: Make sure that the card is completely and squarely seated into the riser socket.
    2. Swing the locking latch into place until it clicks into the locked position.
  5. Install the riser into the controller module:
    1. Align the lip of the riser with the underside of the controller module sheet metal.
    2. Guide the riser along the pins in the controller module, and then lower the riser into the controller module.
    3. Swing the locking latch down and click it into the locked position.
      When locked, the locking latch is flush with the top of the riser and the riser sits squarely in the controller module.
