Replacing a PCIe card

To replace a PCIe card, you must locate the failed PCIe card, remove the riser that contains the card from the controller module, replace the card, and then reinstall the PCIe riser in the controller module.

1. Remove the riser containing the card to be replaced:
   1. Open the air duct by pressing the locking tabs on the sides of the air duct, slide it toward the back of the controller module, and then rotate it to its completely open position.
   2. Remove any SFP or QSFP modules that might be in the PCIe cards.
   3. Rotate the riser locking latch on the left side of the riser up and toward air duct.
      The riser raises up slightly from the controller module.
   4. Lift the riser up straight up and set it aside on a stable flat surface,
2. 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. For risers 2 and 3 only, swing the side panel up.
   4. Remove the PCIe card from the riser by gently pushing up on the bracket and lift the card straight out of the socket.
3. Install the replacement PCIe card in the riser by aligning the card with the socket, press the card into the socket and then close the side panel on the riser, if present.
   Be sure that you properly align the card in the slot and exert even pressure on the card when seating it in the socket. The PCIe card must be fully and evenly seated in the slot.

   Note: If you are installing a card in the bottom slot and cannot see the card socket well, remove the top card so that you can see the card socket, install the card, and then reinstall the card you removed from the top slot.
4. Reinstall the riser:
   1. Align the riser with the pins to the side of the riser socket, lower the riser down on the pins.
   2. Push the riser squarely into the socket on the motherboard.
   3. Rotate the latch down flush with the sheet metal on the riser.
