MegaRAID LSIiBBU07 Intelligent Battery Backup Unit Quick Installation Guide
Connecting an LSIiBBU07 Unit from a Remote Mount Board to a Board-to-Board Adapter
Card on a RAID Controller
Connecting the LSIiBBU07 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, the small triangles that designate pin 1 on
each connector have been marked in black. Make sure that 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
LSI cables.
