1.7.1 Controller Module of RAID Models
The controller on dual-controller models also features a CBM that comprises a BBU
and FBM. The CBM and its components may be optional items for certain systems.
The controller module contains no user-serviceable components. Therefore, except
when installing/upgrading cache memory or installing/replacing a CBM, the controller
module should never be removed or opened.
