Attaching the PCIe Expansion Node to a compute node host

Use this information to attach the PCIe Expansion Node to a compute node host using the 2-bay shelf and install optional devices.

Before attaching a PCIe Expansion Node to a compute node host, complete the following steps:
  1. Read Safety and Installation guidelines.
  2. Verify that the host compute node has two processors installed before you proceed (see the compute node Installation and Service Guide for more information). The second processor is required to drive the expansion node PCIe bus.
  3. If the compute node is operating, shut down the operating system (see the compute node Installation and Service Guide for instructions).
  4. Press the power button to turn off the compute node (see the compute node Installation and Service Guide for instructions).
  5. If the compute node is installed in a Flex System Enterprise Chassis, remove it (see the compute node Installation and Service Guide 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.

To attach a PCIe Expansion Node and compute node host, complete the following steps.

  1. Place the 2-bay shelf on a flat, static-protective surface with the right side of the shelf oriented towards you.
  2. Orient the alignment slots on the bottom of the compute node with the alignment posts on the left side of the 2-bay shelf. Lower the compute node onto the posts; then, slide the compute node towards the center of the shelf until the retention latch clicks into place.

  4. Remove the PCIe Expansion Node cover, if installed (see Removing the cover for instructions).
  5. Remove the compute node cover, if installed (see the compute node Installation and Service Guide for instructions).
  6. Remove the compute node I/O expansion adapters, if installed (see the compute node Installation and Service Guide for instructions).
  7. Remove the I/O expansion adapters from the PCIe Expansion Node, if installed (see Removing an I/O expansion adapter for instructions).
  8. Remove the plastic covers from the interposer connector in the PCIe Expansion Node and the compute node, if installed.
  9. Orient the end of the interposer cable with the attached cable guide to the interposer connector in the compute node. Fit the cable guide over the chassis and press on the blue touch point to seat the interposer cable in the connector.

  10. Orient the free end of the interposer cable to the interposer connector in the PCIe Expansion Node and press the blue touch point to seat the interposer cable in the connector.
  11. Install the compute node I/O expansion adapters, if any were removed (see the compute node Installation and Service Guide for instructions).
  12. Install the compute node cover (see the compute node Installation and Service Guide for instructions).
After attaching the PCIe Expansion Node and compute node host on the 2-bay shelf and connecting the PCIe Expansion Node to the compute node, complete the following steps:
  1. Install optional devices in the PCIe Expansion Node:
    1. To install a full-height adapter, see Installing a full-height adapter
    2. To install a low-profile adapter, see Installing a low-profile adapter
    3. To install an I/O expansion adapter, see Installing an I/O expansion adapter
  2. Close the PCIe Expansion Node cover and install the assembly in the Flex System Enterprise Chassis (see Completing the installation for instructions).
