Installing the LSIiBBU05 Unit
2.2.2.4 Installing the LSIiBB05 LiON Unit Directly on the RAID Controller
Perform the following steps to mount the LSIiBB05 unit directly to the RAID controller using the daughtercard. (All
components are installed on the bottom of the card. The battery is installed on the top. The maximum height of
components installed on the LSIiBBU05 is 0.125”.)
1. Insert the battery pack harness connector at the end of the 5-pin cable into the 5-pin J3 connector on the back
side of the LSIiBB05 unit.
2. With the RAID controller on a flat, clean, static-free surface, hold the LSIiBB05 unit daughtercard so that the
battery side is facing upward, and the J2 board-to-board connector lines up with the J7 BBU connector on the
RAID controller, as shown in the following figure.

3. Carefully press the LSIiBB05 unit onto the controller, so that the two connectors are firmly joined.
4. Use the Phillips-head screws that are provided to secure the LSIiBB05 unit to the controller with the M2.50-0.45 ×
5-mm screws, and the 6-mm standoffs in the three screwholes.
The standoffs are threaded at both ends and a 6mm screw goes into each end.
NOTE Center the screwdriver carefully to avoid stripping the screwhead.
Do not overtighten the screws.
