Removing and Replacing the System or iLO 2 MP Battery
The system and iLO 2 MP batteries are located on the system board. Replace the target battery
with only the identical or equivalent battery. Follow the manufacturer recommendations. Dispose
of used batteries according to the manufacturer instructions.
WARNING! If mishandled, lithium batteries can explode. Do not recharge, disassemble, or
dispose of the battery in a fire. Failure to observe this warning can result in personal injury or
damage to equipment.
Removing the System or iLO 2 MP Battery
WARNING! Ensure that the system is powered off and all power sources are disconnected from
the server prior to performing this procedure.
Voltages are present at various locations in the server whenever an AC power source is connected.
These voltages are present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow
ESD safety precautions can result in damage to the server.
IMPORTANT: Before removing the system battery, record all boot and LAN configuration settings
(find the settings using the INFO ALL EFI command). You must reset these values after replacing
the battery. You can also use the non-volatile RAM configuration backup (NVRAM) backup utility
to back up and store these values. The utility is located at: http://www.hp.com/go/bizsupport.com
Before removing the iLO 2 MP battery, see the HP Integrity iLO 2 Operations Guide for backing
up iLO 2 MP configuration settings.
Two versions of the battery socket have been shipped in rx2660 systems. You can tell which one
you have by checking the Engineering Date Code (EDC) value on your system board. To determine
if your system has an Engineering Date Code (EDC) earlier than 4739, and thus is a candidate
for installing the battery clip, run the Display FRU (DF) command from the iLO 2 MP to obtain the
FRUID. If the second Custom Info field in the FRUID is earlier than 4739 (see example below), your
system is a candidate for the battery clip.
The following FRUID example system shows a board with date code 4747 in the second Custom
Info field and therefore is not a candidate for the battery clip.
