This quick installation guide explains how to install the
LSIiTBBU03 Intelligent Transportable BBU on the MegaRAID
SAS 8888ELP RAID controller.
The iTBBU03 is an intelligent, transportable battery backup
unit that protects the integrity of the cached data on the
MegaRAID controller for up to 72 hours in the event of a
complete AC power failure or a brief power outage. The
iTBBU03 connects directly to the SAS 8888ELP RAID
controller in the MiniDIMM socket.
LSI Logic provides a family of MegaRAID intelligent
transportable battery backup units (iTBBUs) for use with its
high-performance MegaRAID RAID controllers. The
MegaRAID iTBBUs provide an inexpensive alternative to
using an uninterruptible power supply (UPS) and a second
level of fault tolerance when used in conjunction with a UPS.

battery.

iTBBU03. (The “top” side is the side you can see after you
install the iTBBU03 on the motherboard or server chassis.)

Note:
The only functional difference between the iBBU
and the iTBBU is that the battery unit is
integrated into the cache DIMM itself on the
iTBBU. This integration enables you to transfer
the DIMM assembly from a faulty RAID controller
to a new RAID controller and to fully recover
unwritten cache data.

Follow these steps to install the iTBBU03 on the MegaRAID
SAS 8888ELP RAID controller. The battery is installed on
the top of the controller.
Step 1
Ground yourself, and remove the iTBBU03 and
the daughtercard from the package.
Step 2
Insert the J1 battery pack harness connector at
the end of the colored wires into the 5-pin
connector in the opening in the corner of the
iTBBU03.
Step 3
With the front side up, place the iTBBU03 front-
side-up on a flat, clean, static-free surface.
Step 4
With the front side up, place the MegaRAID SAS
8888ELP RAID controller on a flat, clean, static-
free surface.
Step 5
Mount the iTBBU03 in the MiniDIMM memory
socket on the RAID controller as you would a
standard DIMM, as shown in
.
Electrostatic discharge can damage the iTBBU03
and the MegaRAID SAS RAID controller. Make
sure that you install the iTBBU03 at an ESD-safe
workstation that meets the requirements of EIA-
625 – “Requirements For Handling Electrostatic
Discharge Sensitive Devices.” When you install
the iTBBU03, follow the ESD-recommended
practices in the latest revision of IPC-A-610.
The iTBBU03 and the integrated charging
circuitry were specifically designed for Li-Ion
Polymer battery cells. Attempts to self service or
replace any original component could result in an
explosion or a fire. Please dispose of used
batteries in accordance with local laws.
