Installing the LSIiBBU06 Unit
2.3.5.3 Connecting the Cable between the Board-to-Board Adapter Card on the RAID Controller and the LSIiBBU06
Unit on the System Chassis
Follow these steps to connect the cable between the board-to-board adapter card on the RAID controller and the
LSIiBBU06 unit.
1. Ground yourself, and remove the LSIiBBU06 unit from the package.
2. Use the three Phillips-head screws that are provided to secure the LSIiBBU06 unit to the motherboard or the
server chassis.
3. Insert the battery pack harness connector at the end of the colored wires into the J4 connector on the rear side of
the LSIiBBU06 unit.
4. Insert the 20-pin cable connector at one end of the 12-in. cable into the 20-pin J2 cable connector on the
LSIiBBU06 unit and the 20-pin cable connector at the other end into the 20-pin JT1 battery backup connector on
the board-to-board cable adapter daughter card, as shown in the following figure.
CAUTION Damage to the battery backup unit will occur when power is applied
to the system if the cable assembly connectors are installed backwards
in either the JT1 board-to-board connector or the J2 battery
connector. The cable connectors are polarized, and the keying features
of the connector are designed to allow the connectors to be attached
in only one orientation. The cable end inserts into the connector with
only minimal resistance.
Even with the keying features, if excessive force is used, it is possible
to install these connectors incorrectly. To assist in correct alignment,
the small triangles that designate pin 1 on each connector have been
marked in black. Be sure these triangles line up as shown in the
illustrations. Also, the wire that connects to pin 1 of each end of the
cable assembly is yellow on most Avago cables.
