MegaRAID LSIiBBU07 Intelligent Battery Backup Unit Quick Installation Guide
MegaRAID LSIiBBU07 Intelligent Battery Backup Unit Quick
Installation Guide
Thank you for purchasing the LSI® MegaRAID® LSIiBBU07 product. Before you install your RAID controller, take a few
minutes to read this quick installation guide. This guide explains how to install the LSIiBBU07 unit directly on your
RAID controller or connect the LSIiBBU07 unit remotely to the RAID controller.
LSI provides a family of MegaRAID intelligent battery backup units (iBBUs) for use with its high-performance
MegaRAID RAID controllers. The LSI MegaRAID iBBUs provide an inexpensive alternative to using an uninterruptible
power supply (UPS) and a second level of fault tolerance when used with a UPS.
If you need more information about any topic covered in this guide, refer to the related documents on your MegaRAID
Universal Software Suite CD.
Product Overview
The LSIiBBU07 unit is a lithium ion (LiON), intelligent battery backup unit that protects the integrity of the cached data
on a MegaRAID controller for up to 72 hours (depending on the derated retention time selected) in the event of a
complete AC power failure or a brief power outage. The LSIiBBU07 unit is based on Lithium ion (LiON) battery
cell technology.

batteries according to the manufacturer’s instructions.
1. Ground yourself, and make sure that the system is grounded.
2. Remove the LSIiBBU07 daughter card from the package.
3. Insert the battery pack harness connector at the end of the wires into the 5-pin J4 connector on the back side of
the LSIiBBU07 unit, as shown in the rear view in Figure 1.
4. Place the LSIiBBU07 unit with its front side facing upward on a flat, clean, static-free surface.
5. Place the RAID controller with the front side facing upward on a flat, clean, static-free surface.
6. Hold the LSIiBBU07 daughter card so that the battery side is facing up and the J5 connector lines up with the J1
BBU connector on the SAS 8880EM2 RAID controller, as shown in the following figure.

7. Carefully press the LSIiBBU07 daughter card onto the RAID controller so that the two connectors are joined firmly.
8. Secure the LSIiBBU07 daughter card to the RAID controller with the screws and the standoffs in the three screw
holes, and continue with the following procedure.
The standoffs are threaded at both ends, and a screw fits into each end. The screw threads from the back of the
controller board into the board-to-board standoff on the bottom of the LSIiBBU07 daughter card.
NOTE Center the screwdriver carefully to avoid stripping the screw heads. Do not overtighten the screws.
