System battery information System battery information
The server contains an internal lithium manganese dioxide, a vanadium pentoxide, or an alkaline battery that provides power to the
real-time clock. If this battery is not properly handled, a risk of the 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 expose the battery to extremely low air pressure as it might lead to explosion or leakage of flammable liquid or gas.
Do not disassemble, crush, puncture, short external contacts, or dispose the battery in fire or water.
If the server no longer automatically displays the correct date and time, then replace the battery that provides power to the real-
time clock. Under normal use, battery life is 5 to 10 years.
