Installing the LSIiBBU08 Unit
2.5.6.3
Connecting the Cable Between the LSIiBBU08 Unit on the Remote Mount Board and the Adapter Card on the
RAID Controller
Follow these steps to connect the cable between the LSIiBBU08 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
LSIiBBU08 unit on the remote mount board, as shown in the following figure.
3.
Insert the 20-pin cable connector at the other end of the 12-in. cable into the 20-pin J1 connector on the
board-to-board cable adapter card that is installed on the RAID controller, as shown in the following figure.
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 J1 connector on the board-to-board cable adapter card or
on the J2 BBU 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 are marked
in black. Make sure these triangles line up as shown in the
illustrations. The wire that connects to pin 1 of each end of the cable
assembly is yellow on most Avago cables.
