Replacing the system board

Use these instructions to replace the PCIe Expansion Node system board.

Before you replace the PCIe Expansion Node system board, complete the following steps:
  1. Read Safety and Installation guidelines.
  2. If the PCIe Expansion Node is installed in a Flex System Enterprise Chassis, remove it (see Removing a PCIe Expansion Node and attached compute node host for instructions).

CAUTION
Hazardous energy is present when the blade is connected to the power source. Always replace the blade cover before installing the blade.

Note
The PCIe Expansion Node enclosure and system board are replaced as a unit.

To replace the expansion node system board, complete the following steps.

  1. Remove the PCIe Expansion Node cover, if installed. (see Removing the cover for instructions).
  2. Remove all of the internal components from the expansion node enclosure and place them on a flat static-protective surface for reuse.
    1. Remove the full-height PCIe riser assembly (see Removing the full-height PCIe riser for instructions). Do not remove the adapters or fillers that are installed in the riser.
    2. Remove the low-profile PCIe riser assembly (see Removing the low-profile PCIe riser for instructions). Do not remove the adapters or fillers that are installed in the riser.
    3. Remove the I/O expansion adapters, if installed (see Removing an I/O expansion adapter for instructions).
    4. Remove the interposer cable, if installed (see Removing the interposer cable for instructions).
  3. If you are instructed to return the expansion node enclosure, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
  4. Install the following internal components in a new PCIe Expansion Node enclosure:
    1. Install the low-profile PCIe riser assembly (see Installing the low-profile PCIe riser for instructions).
    2. Install the full-height PCIe riser assembly (see Installing the full-height PCIe riser for instructions).
After installing the PCIe risers in a new the expansion node enclosure, complete the following steps:
  1. Attach the PCIe Expansion Node to the 2-bay shelf, install the interposer cable, and install the I/O expansion adapters, if any were removed (see Attaching the PCIe Expansion Node to a compute node host for instructions).
  2. Close the cover and install the 2-bay shelf assembly into the Flex System Enterprise Chassis (see Completing the installation for instructions).
