Chapter 2: Installing the Cache Backup Products

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.

4. Battery Pack Harness

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.
