6. Repeat for all drives to be installed into the B08S2-PS.
Note
The hard drives in a RAID system should match in size and speed. All drives
in an array should be identical models with the same firmware version.
3.1.2 Installing the HBA Card
Before the ExaSAN B08S2-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 for best performance.
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” up position, the HBA card is enabled for RAID
(Direct-Attached Storage B08S2-PS) mode.
• SAN mode: In the “1” down position, the HBA is enabled for switch (SAN) mode.

4. Locate the available PCIe slot; remove the blank plate if one is present, save the screw for later use.
