WARNING!
The MUX kits are small, delicate components that must be handled with
care. If the need should arise, handle the MUX board by the board edges
and avoid touching PCB traces and connector pins.

RAID
Controller
Module
Figure 1-7: RAID Controller Module
PN: GAL-83AF24RE16M5 (w/ a 512MB DIMM)
The RAID controller module within your subsystem contains a controller
board, a BBU adapter board, an interface faceplate, and a pre-installed DDR
RAM DIMM module. The BBU adapter board is mounted on top of the
main circuit board and is not user-serviceable. The DDR RAM DIMM
socket is strategically placed on an easily accessible location. (See
Figure
1-7
) A BBU slot on the top center of the controller module receives a BBU
module.
The controller module contains no user-serviceable components. Except
when installing/upgrading the cache memory inside or replacing a failed
controller, the controller module should never be removed from the chassis.

WARNING!
Although the RAID controller can be removed, the only time you should
touch the controller itself is to install/upgrade the memory modules. The
RAID controller is built of sensitive components and unnecessary
tampering can damage the controller.
