5.5 Replacing the CBM for RAID Models
Upgradeable/replaceable components are listed below.
 BB: In the event of a power failure, the BBU can be used to store/ save cached
data in the DRAM module for up to 72 hours with super capacity BBU.
 BBU + FBM: In the event of a power failure, the combination of BBU+ FBM
(non-volatile flash storage) can be used to store data indefinitely.
The CBM consists of a BBU and FBM. The CBM can sustain and transfer cached
data to a FBM in the event of a power outage, or in the unlikely event of both PSUs
failing.
The CBM (BBU and FBM) is an optional item for single-controller systems by default.
Warning! Ensure that the replacement module(s) are on hand before attempting
to replace the CBM.
Ensure the FBM has been installed before installing the BBU. Please
refer to the procedures mentioned in the “Installing the BBU” section.
