LSI iTBBU03 QIG User guide

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.

Note: See the MegaRAID 1078 Battery Backup Unit

User’s Guide for detailed information about this

battery.

Figure 1 shows the top view and the bottom view of the

iTBBU03. (The “top” side is the side you can see after you

install the iTBBU03 on the motherboard or server chassis.)

Unit

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.

Installing the iTBBU03 on the SAS

8888ELP RAID Controller

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 Figure 2.

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.

The memory socket is mounted flush with the

RAID controller. The iTBBU03 is parallel to the

RAID controller when properly installed.

Socket on the MegaRAID SAS 8888ELP

RAID Controller

Step 6 Press the iTBBU03 firmly into the memory

socket.

As you press the iTBBU03 into the socket, it

clicks into place when it is properly seated in the

socket. The arms on the sides of the socket

rotate into the notches on the sides of the

iTBBU03 to hold it securely in place.

Step 7 Install the MegaRAID SAS 8888ELP RAID

controller in the computer, as shown in Figure 3.

Press down gently, but firmly, to ensure that the

RAID controller is properly seated in the slot. The

bottom edge of the RAID controller must be flush

with the slot.

Caution: Never apply pressure to the LSIiTBBU03 or to the

DIMM when inserting the SAS 8888ELP RAID

controller. Instead, press down only on the top

edge of the RAID controller, as shown in Figure 3.

Step 8 Attach the RAID controller to the computer

chassis with the bracket screw.

Step 9 Attach the cables, as needed, to the connectors

on the RAID controller.

Step 10 Replace the computer cover, and reattach the

power cord(s).
