Installing an HPE InfiniBand HDR/Ethernet 940QSFP 56x16 adapter

The server supports installing two adapters in a four-processor configuration and one adapter in a two-processor configuration. Each adapter requires the installation of an auxiliary card in a supported slot.

Use the following table to determine the supported slot locations:

Processors Adapter slot Auxiliary card slot
2 6 13
4 2 9
4 11

For more information on expansion slot numbering, see Rear panel components.

WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment, remove power from the server by removing the power cord. The front panel Power On/Standby button does not shut off system power. Portions of the power supply and some internal circuitry remain active until AC power is removed.
CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless all PCI slots have either an expansion slot cover or an expansion board installed.
Prerequisites

Before you perform this procedure, make sure that you have the following items available:

  • The components included with the hardware option kit

  • T-10 Torx screwdriver

  • HPE InfiniBand HDR PCIe G3 Auxiliary card with 350mm cable kit

  • 7 slot riser board installed in the primary and secondary riser cages

Procedure
  1. Power down the server.
  2. Remove all power:
    1. Disconnect each power cord from the power source.
    2. Disconnect each power cord from the server.
  3. Do one of the following:
  4. Remove the access panel (Removing the access panel).
    CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.

  5. Depending on your configuration, remove the primary riser cage, secondary riser cage, or both (Removing a PCIe riser cage).
  6. Remove the expansion slot blanks from the required slots.

    The primary PCIe riser cage is shown.

  8. Open the cable latch door, connect the auxiliary card cables to the adapter ports so that the golden side of the cable connector is on the top, and then close the cable latch door.

    The white and black cables from the auxiliary card connect to the expansion board ports labeled WHITE CABLE and BLACK CABLE, respectively.

    The cable latch door must be open when connecting the cables.

    CAUTION:

    The connector pins are fragile and easily damaged. To avoid damaging the connector pins, do not use excessive force when connecting the cables.
