Removing the Transportable Battery Backup Unit (TBBU)
from a PERC x/E Adapter
This section describes the procedure to remove the TBBU from a PERC x/E
Adapter installed in a system.
NOTE: The TBBU on the PERC x/E Adapter consists of a dual in-line memory
module (DIMM) and a battery backup unit (BBU).
1
Perform a controlled shutdown of the system in which the PERC x/E
Adapter is installed, as well as any attached storage enclosures, and remove
the PERC

2
Visually inspect the controller and determine whether the dirty cache LED
on the memory module is turned on. See Figure 1. If the LED is turned on,
reinsert the controller into the system, replace the system cover, reconnect
the system to the electrical outlet, turn on the system, and repeat step 1.

Remove the TBBU assembly from the PERC x/E Adapter by pressing down
on the tabs at each edge of the memory module connector and lifting the
TBBU off the adapter.
4
Disconnect the battery cable from the memory module.
NOTE: Do not exert excessive pressure on the connector on the memory
module while removing the memory module.
5
Detach the battery from the memory module by pressing out on the
battery clips inserted through the memory module and rotating the
battery off the memory module. See Figure 2.

.
Unpack the BBU and follow all antistatic procedures.
NOTE: All work must be performed at an Electrostatic Discharge (ESD)-safe
workstation to meet 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.
NOTE: Handle all sensitive components in a static-safe area. If possible,
use antistatic floor pads and work bench pads.
NOTE: When unpacking a static sensitive component from its shipping
carton, do not remove the component from the antistatic packing material
until you are ready to install the component. Just before unwrapping the
antistatic package, be sure to discharge static electricity from your body.
With the memory module removed from the controller, insert one end
of the battery cable (the red, white, yellow, and green wires) into the
connector on the memory module and the other end into the connector
on the battery.
NOTE: Do not exert excessive pressure on the connector on the memory
module while installing the memory module.
6Removing and Installing the Battery and Battery Cable on PERC Controllers
3
Place the top edge of the battery over the top edge of the memory module
so that the arms on the side of the battery fit into their sockets on the
memory module. See Figure 3.
CAUTION: Electrostatic discharge can damage sensitive components.
Always use proper antistatic protection when handling components.
Touching components without proper grounding can damage the equipment.

Place the PERC x/E Adapter on a flat, clean, and static–free surface.
5
Mount the memory module on the controller memory socket like a
4
standard DIMM. See the section "Installing the TBBU on a PERC x/E
Adapter"for more information.
The memory module is mounted flush with the board so that the memory
module is parallel to the board when installed.
6
Press the memory module firmly into the memory socket. As you press the
memory module into the socket, the BBU clicks into place, indicating that
the controller is firmly seated in the socket, and the arms on the socket fit
into the notches to hold the memory module securely.

CAUTION: Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. Before performing any
procedure, see your Product Information Guide for complete information about
safety precautions, working inside the computer, and protecting against
electrostatic discharge.
NOTE: The TBBU on the PERC x/E Adapter consists of a dual in-line memory
module (DIMM) and a battery backup unit (BBU).
1
Remove the memory module in an antistatic environment.
NOTE: When unpacking a static-sensitive component from its shipping
carton, do not remove the component from the antistatic packing material
until you are ready to install the component. Just before unwrapping the
antistatic package, be sure to discharge static electricity from your body.
NOTE: Handle all sensitive components in a static-safe area. If possible,
use antistatic floor pads and work bench pads.
NOTE: Never touch the gold leads and do not bend the memory module.
2
Align the memory module so that the keyed edge of the memory module is
placed exactly on top of the physical divider on the memory socket of the
controller. This will avoid damage to the memory module.
3
Insert the memory module on the memory socket of the controller and
apply a smooth, downward pressure on both ends or on the middle of the
memory module until the retention clips fall into the allotted slots on
either side of the memory module. Figure 4 displays the installation of
a memory module on a PERC
x
/E Adapter.
