Installing the LSIiBBU07 Unit
2.4.6.3 Connecting the LSIiBBU08 Unit on the Remote Mount Board to the Board-to Board Cable Adapter Card on the
RAID Controller
Follow these steps to connect the cable between the LSIiBBU07 unit on the remote mount board and the
board-to-board adapter card on the 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
LSIiBBU07 unit on the remote mount board and the 20-pin cable connector at the other end into the 20-pin J1
connector on the board-to-board adapter card on the RAID controller.
Black triangles on the connectors help you install the connectors correctly. Insert the cable connectors into the
controller connector and the iBBU connector so that the black triangles are aligned, 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,
small black triangles designate pin 1 on each connector. Make 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.
