Removing the NVRAM card

Replacing the NVRAM consist of removing the NVRAM riser, Riser 1, from the controller module, disconnecting the NVRAM battery from the NVRAM card, removing the failed NVRAM card and installing the replacement NVRAM card, and then reinstalling the NVRAM riser back into the controller module.

Steps

  1. If you are not already grounded, properly ground yourself.
  2. Remove the NVRAM riser, Riser 1, from the controller module:
    1. Rotate the riser locking latch on the left side of the riser up and toward the fans.
      The NVRAM riser raises up slightly from the controller module.
    2. Lift the NVRAM 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 straight up out of the controller module, and then place it on a stable, flat surface so that you can access the NVRAM card.

  3. Remove the NVRAM card from the riser module:
    1. Turn the riser module so that you can access the NVRAM card.
    2. Unplug the NVRAM battery cable that is attached to the NVRAM card.
    3. Press the locking bracket on the side of the NVRAM riser, and then rotate it to the open position.
    4. Remove the NVRAM card from the riser module.
  4. Install the NVRAM card into the NVRAM riser:
    1. Align the card with the card guide on the riser module and the card socket in the riser.
    2. Slide the card squarely into the card socket.
      Note: Make sure that the card is completely and squarely seated into the riser socket.
    3. Connect the battery cable to the socket on the NVRAM card.
    4. Swing the locking latch into the locked position and make sure that it locks in place.
  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.
    4. Reinsert any SFP modules that were removed from the PCIe cards.
