The controller on the dual controller models also features a Cache Backup Module
(CBM), consisting of a Battery Backup Unit (BBU) and Flash Backup Module (FBM).
The CBM and its components may be optional items for some systems.
The controller module contains no user-serviceable components except when users
are installing/ upgrading the cache memory or installing/replacing a CBM, the
controller module should never be removed or opened.
NOTE
The Ethernet management port supports only 100Mbs and 1000Mbs (1Gbs) speeds.
The battery backup unit (BBU) is an optional accessory for single controller systems.
WARNING
The only time you should remove the controller is to install/replace the memory
modules, CBM or a failed controller. The RAID controller is built of sensitive
components and unnecessary tampering can damage the controller.
