3.1.2 Installing the HBA Card
Before the ExaSAN A12S2-PS is ready to be connected and powered on, you must install
the HBA card in the workgroup client system. The HBA card is compatible with PCIe x4,
x8, and x16 slots. If a choice is given, use the fastest PCIe slot available. Although the
HBA card is compatible with both PCIe 1.1 and 2.0 standards, only the latter is
recommended due to performance consideration.
Caution
PCIe slots on some motherboards are for graphics cards only.
Check with the motherboard vendor for compatibility.
Follow these steps to install the card in each host system:
1.
Make sure that the client system is turned off.
2. Open the client system’s outer casing cover, check with your vendor
documentation for instructions if necessary.
3. Re-position the HBA card so that you are facing jumper switch as shown below. You
can use the jumper switch to configure the HBA for DAS or SAN usage. Set the
jumper switch before installing into the host
 DAS mode: When the switch is in the "On” position, the HBA card is enabled for
RAID (Direct-Attached Storage A12S2-PS) mode.
 SAN mode: In the “1” position, the HBA is enabled for switch (SAN) mode.
