The MegaRAID intelligible Transportable Battery Backup Module 2
(LSIiTBBU02) is a cache memory module with an integrated battery
pack. The module provides an uninterrupted power source to the module
if power is unexpectedly interrupted while cached data is still present. If
the power failure is the result of the MegaRAID 8480 Storage Adapter
itself failing, then the LSIiTBBU02 can be moved to a new controller and
the data can be recovered. The replacement controller must have a
cleared configuration.
Note:
See the Warranty and Support Information document for
the replacement battery part number and battery-disposal
instructions.
