Removing and replacing the PDH battery (system battery)
If the server no longer automatically displays the correct date and time, you might have to replace
the battery (see Table 40
CRU List) that provides power to the real-time clock.
WARNING!
The computer contains an internal lithium manganese dioxide, a vanadium pentoxide,
or an alkaline battery pack. If the battery pack is not properly handled, a risk of fire and burns
exists. To reduce the risk of personal injury:
•
Do not attempt to recharge the battery.
•
Do not expose the battery to temperatures higher than 60°C (140°F).
•
Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water.
•
Replace only with the spare designated for this product.
1.
Power off the server (
“Powering off the server” (page 99)
).
2.
Extend the server from the rack (
“Extending the server from the rack” (page 95)
).
3.
Remove the access panel (
“Removing and replacing the access panel” (page 106)
).
4.
Remove the PCI riser cage (
“Removing and replacing the PCI riser cage” (page 111)
).
CAUTION:
Do not attempt to remove the battery by hand. Doing so can cause the battery
holder to separate from the system board.
CAUTION:
Do not attempt to remove the battery from the side marked “+” first. If your battery
holder does not have the “+” marking, the side of the holder with springs will be the “+” end.
5.
Using a nonconductive tool small enough to fit into the battery slot as leverage, gently remove
the battery from the holder from the end marked “---“.
NOTE:
HP recommends using ESD safe, non-conductive tweezers or a similar tool.
To replace the component, reverse the removal procedure.
IMPORTANT:
Ensure that the new battery is fully seated and that all locking tabs are correctly
engaged.
For more information about battery replacement or proper disposal, contact an authorized reseller
or an authorized service provider.
