Hardware Installation Instructions
Figure 1 Install the 9400-8i8e Tri-Mode HBA in a PCIe Slot
6.
Connect the cables between the adapter and the mid-plane or storage devices.
The 9400-8i8e Tri-Mode HBA has two SFF-8643 internal x4 mini-
SAS HD connectors and two SFF-8644 external x4 mini-SAS HD connectors.
• For SAS/SATA connections, connect standard 12Gb/s SAS cables with internal or external mini-SAS HD connectors on one end to the adapter and
the appropriate connector on the other end to attach to the backplane, enclosure, or SAS/SATA devices.
• For PCIe/NVMe connections, use the appropriate U.2 enabler cable to enable connection to the backplane connectors, as shown in the following
figure. The U.2 enabler cable routes the REFCLK, sidebands, and PCIe signals to the appropriate pins on the backplane connector. Different U.2
enabler cables are available, depending on the backplane connector type. Using standard 12Gb/s SAS cables for NVMe connections might result in
damage to the PCIe adapter or the drive. For more information, refer to the
Storage Adapter Cable Guide
and the

Mode Storage Adapters User Guide

CAUTION:
For NVMe connections to an SFF-8639 (U.2) bay or connections to a PCIe switch, use only approved cables with REFCLK forwarded on
the proper pins. Improperly connecting a standard 12Gb/s SAS cable to an SFF-8639 bay can damage the adapter and the drive.
