2. Attach the low-prole bracket to the controller board. The low-prole bracket is installed on the back
side of the controller, with the mounting screws inserted from the front of the controller, as shown the
Figure 3.
Insert the screws through the holes on the front of the controller, then fasten the screws to the bracket
with a Phillips screw driver.
Caution: The mount points on the low-prole bracket have a smooth or at side and
a raised side that looks like a spacer (see Figure 3). Be sure to install the bracket with
the at side against the controller PCB and the raised side facing away from the PCB.

Caution: The torque on the mounting screws should be a maximum of 3.0-4.0 lbf-in
to avoid deformation. Be sure that the controller is not bent after attaching the
low-prole bracket to the controller board.
4.4 Installation Options
When you install your Microsemi Adaptec RAID controller, you can choose to create a bootable array and
then install your operating system and the controller driver on that array.
Alternatively, you can complete a standard installation, where the controller driver is installed on an existing
operating system.
