System battery replacement
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.
