This quick installation guide explains how to install the

LSI Logic MegaRAID iTBBU02 Intelligent Transportable

Battery Backup Unit on MegaRAID SAS 8480E and

MegaRAID SAS 8408E RAID storage adapters. The

iTBBU02 protects the cached data on the MegaRAID

storage adapter by providing backup power if the main AC

power source fails or is interrupted.

The iTBBU02 is compliant with the Smart Battery Data

Speciﬁcation, which relieves the host system from the

responsibility of communicating battery information and

charging the battery. Battery charging and recharging take

place automatically.

You can view information about the iTBBU02, such as

battery temperature and voltage, in the BIOS Conﬁguration

Utility. See the MegaRAID Conﬁguration Software User’s

Guide or the MegaRAID Storage Manager User’s Guide for

more information about the conﬁguration utility.

Installing the iTBBU02 on the Storage

Adapter

If the MegaRAID SAS storage adapter is already installed in

a computer, follow these steps to remove it before you install

the iTBBU02:

Step 1 Shut down the computer, turn off the power, and

unplug the power cord(s).

Step 2 Remove the cover from the computer, according

to the instructions in the system user’s manual, to

access the PCI Express slots.

Step 3 Ground yourself before touching the MegaRAID

SAS storage adapter.

Step 4 Unplug all cables from the MegaRAID

SAS storage adapter, remove the screw attaching

the bracket to the computer case, and carefully

remove the storage adapter from the slot.

Step 5 Place the storage adapter on a ﬂat, clean, static-

free surface, and continue with the next

procedure.

Perform the following steps to install the iTBBU02 on the

DIMM and MegaRAID SAS storage adapter.

Step 1 Ground yourself and remove the iTBBU02 from

its package.

The following ﬁgure shows front and back views

of the iTBBU02.

Step 2 Place the iTBBU02 and DIMM front-side-up on a

ﬂat, clean, static-free surface.

Step 3 Place the iTBBU02 on the DIMM so that the front

side is up and the holes for the screws line up

with the holes on the iTBBU02, as shown below.

Electrostatic discharge can damage the iTBBU02

and the MegaRAID SAS storage adapter. Be

sure to install the iTBBU02 at an ESD-safe

workstation that meets the requirements of EIA-

625 – “Requirements For Handling Electrostatic

Discharge Sensitive Devices.” When you install

the LSIiBBU01, follow the ESD-recommended

practices in the latest revision of IPC-A-610.

CAUTION

There is danger of an explosion if the battery is

incorrectly replaced. Replace it only with the

same or equivalent type recommended by the

Step 4 Using a Philips-head screwdriver, secure the

iTBBU02 to the DIMM.

Step 5 Insert the battery pack harness connector (at the

end of the colored wires) into the 5-pin J1

connector on the DIMM.

Note: The battery pack harness connector is polarized

and can be inserted into the J1 board battery

connector only if the rails on the harness

connector align with the slots on the J1

connector.

Step 6 Insert the DIMM and iTBBU02 into the DIMM

socket on the SAS storage adapter, as shown

below.

Step 7 Close the arms to secure the DIMM and

iTBBU02.

Step 8 Install the MegaRAID SAS storage adapter in a

PCI Express slot in the computer.

Press down gently, but ﬁrmly, to ensure that the

storage adapter is properly seated in the slot. The

bottom edge of the storage adapter must be ﬂush

with the slot.

Step 9 Secure the storage adapter to the computer

chassis with the bracket screw.

Step 10 Attach the cables, as needed, to the connectors

on the MegaRAID SAS storage adapter.

Step 11 Replace the computer cover and reattach the

power cord(s).

Center the screwdriver carefully to avoid stripping

the screw heads. Do not over-tighten the screws.

The maximum recommended torque is 2.25 inch

pounds.

CAUTION

Never apply pressure to the iTBBU02 when

inserting the adapter. Instead, press down only

on the top edge of the storage adapter board, as

shown below.
