Installing the LSIiBBU01 Unit
2.1.1 Installing the LSIiBBU01 (NiMH) Unit
The NiMH version of the LSIiBBU01 unit is offered with a 12-in. cable to connect the unit remotely to the MegaRAID
SAS 8888ELP RAID controller. Battery charging and recharging take place automatically.
The following figure shows the top view and the bottom view of the LSIiBBU01 unit. (The top view is the side that you
can see after you install the unit on the motherboard or server chassis.) Note the J2 connector and the holes for the
screws that attach the LSIiBBU01 unit to the chassis.

The LSIiBBU01 does not mount directly to the MegaRAID controller. Instead, use the supplied 10-in. cable to connect
the LSIiBBU01 unit to a RAID controller, as shown in the example in the following figure. The battery backup unit must
be mounted inside the chassis within 12 in. of the RAID controller.
NOTE Because server and workstation chassis vary from vendor to vendor,
there is no standard mounting option that is compatible with the
various system configurations. Therefore, the LSIiBBU01 battery kit
contains only the battery and the cable, allowing value-added
resellers (VARs) and chassis manufacturers to customize the location
of the remote battery to provide the most flexibility within
various environments.
