12G SAS Expander Card

Before installing the 12G SAS Expander Card, observe the following requirements:

  • The following components must be installed:
    • Storage controller
    • Drive cages:
      • For 24SFF drive configuration—Bay 1 and bay 2 8SFF front drive cages
      • For 12LFF drive configuration—12LFF front drive cage
      • For configurations using the rear drive cage—2SFF rear drive cage or 3LFF rear drive cage
  • The preferred slot to install the SAS expander card is slot 3 of the primary PCI riser cage, if the slot is not occupied. It is not supported in the secondary PCI riser cage.
  • To ensure cables are connected correctly, observe the labels on the cable and component connectors.
  • Be sure you have the latest firmware for the controllers, HBAs, and the expander card. To download the latest firmware, see the Hewlett Packard Enterprise website.
