WARNING!
Although the RAID controller can be removed, the only time you
should touch the controller itself is to install or replace the memory
module and CBM. The RAID controller is built of sensitive
components and unnecessary tampering can damage the
controller.
The docking connector at the rear of the controller board connects the
controller module to the backplane board.
1.2.3 Controller Module Interfaces
The controller interfaces are accessed through the controller
faceplate as shown in the figure below.
