The LSITBBU04 (transportable battery backup unit) protects
the cached data on the MegaRAID SCSI 320-4X storage
adapter by providing backup power if the main power source
fails. Follow the steps in this document to install the
LSITBBU04 on the MegaRAID 320-4X.
The battery pack is already mounted on the MegaRAID
memory module, as shown in the bottom view of LSITBBU
in the following figure. (The “top” side is the side you can see
after you install the TBBU04 on the storage adapter.)
Note:
All work must be performed at an ESD-safe
workstation meeting the requirements of EIA-625
– “Requirements For Handling Electrostatic
Discharge Sensitive Devices”. All actions must be
performed following the IPC-A-610 latest revision
ESD-recommended practices.
If the MegaRAID SCSI 320-4X storage adapter is already
installed in a computer, follow these steps to remove it before
you install the LSITBBU04:
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 so
you can access the MegaRAID SCSI 320-4X
storage adapter.
Step 3
Ground yourself before touching the storage
adapter.
Step 4
Unplug all cables from the MegaRAID SCSI 320-
4X 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 MegaRAID SCSI 320-4X storage
adapter front-side-up on a flat, clean, static-free
surface.
Follow these steps to install the LSITBBU04 on the
MegaRAID SCSI 320-4X storage adapter:
Step 1
Ground yourself and remove the LSITBBU04
from its package.
Step 2
Insert the battery pack harness connector (at the
end of the colored wires) into the 5-pin J1
connector on the bottom of the LSITBBU04.
Step 3
Mount the LSITBBU04 in the storage adapter
memory socket like a standard DIMM, as shown
in the following figure.
The LSITBBU04 is mounted flush with the
storage adapter, so it is parallel to the storage
adapter when properly installed.
Step 4
Press the LSITBBU04 firmly into the memory
socket.
As you press the LSITBBU04 into the socket, it
clicks into place when it is properly seated in the
LSITBBU04 (Top View)
