Installing the LSIiBBU06 Unit
2.3.6.3 Connecting the Cable Between the LSIiBBU06 Unit on the Remote Mount Board and the Board-to-Board Cable
Adapter Card on the RAID Controller
Follow these steps to connect the cable between the LSIiBBU06 unit on the remote mount board and the
board-to-board cable adapter card on your RAID controller.
1. With the controller on a flat, clean, static-free surface, ground yourself, and make sure that the system
is grounded.
2. Insert the 20-pin cable connector at one end of the 12-in. cable into the 20-pin J2 cable connector on the
LSIiBBU08 unit on the remote mount board and the 20-pin cable connector at the other end into the
20-pin JT1 board-to-board cable adapter daughter card on the RAID controller.
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.
