Installing the HPE 12G SAS Expander Card

Hewlett Packard Enterprise recommends installing the SAS expander card in slot 2 of the primary PCIe riser cage.

To ensure that cables are connected correctly, observe the labels on the cable and component connectors.

Be sure that you have the latest firmware for the controllers, HBAs, and the HPE 12G SAS Expander. To download the latest firmware, see the Hewlett Packard Enterprise website (http://www.hpe.com/support/hpesc).

Prerequisites

The 12G SAS Expander Card supports up to 24 SFF drives, depending on which options are also installed in the server.

The following components must be installed:

  • Storage controller

  • Drive cages

    • 24SFF drive configuration—Bay 1, bay 2, and bay 3 installed with 8SFF front drive cages

    • 18SFF drive configuration—Bay 1 Universal Media Bay installed with 2SFF drive cage option, and bay 2 and bay 3 installed with 8SFF front drive cages.

    • 16SFF drive configuration—Bay 2 and bay 3 installed with 8SFF drive 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. If installed, do the following:
    1. Remove the air baffle (Removing the air baffle).
    2. Remove the processor mezzanine tray (Removing the processor mezzanine tray).
    3. Remove the joint board (Removing the CPU Mezzanine UPI performance kit).
    4. Remove the CPU Mezzanine UPI performance kit (Removing the CPU Mezzanine UPI performance kit).
  6. Remove the fan cage (Removing the fan cage).
  7. Remove the primary PCIe riser cage (Removing the PCIe riser cages).
  8. Remove the expansion slot blank from slot 2.
  9. Using the labels on the cables to determine the correct connections, connect the cables to the SAS expander card.
    1. Depending on the ports on the controller, connect the appropriate controller cables to the SAS expander card.
    2. Depending on the drive configuration, connect the appropriate drive cage cables to the SAS expander card.
