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.
WARNING: The computer contains an internal lithium manganese dioxide, a vanadium
pentoxide, or an alkaline battery pack. A risk of fire and burns exists if the battery pack is not
properly handled. 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.
To remove the component:
1. Power down the server (on page 15).
2. Remove all power:
a. Disconnect each power cord from the power source.
