Replacing the FBM (Flash Backup Module)
You can install two FBMs in the controller. If there are two host boards installed, you must remove the
second host board if you want to gain access to both FBMs.
NOTE: Refer to section 4.1.6 Replacing the host board when replacing/uninstalling a host board.
To replace the FBM:
1. Shut down your system, unplug the power cords, then remove the controller. Wait for a minute for
the remaining electric current to dissipate.
NOTE: See section 4.1.3 Replacing the controller module for details.
2. Loosen the screw (A) that secures the FBM to the controller, then lift it up to a 45° angle (B) and
remove it from the board.
