Removal and Replacement Procedures

System Battery

The server uses nonvolatile memory that requires a battery to retain system information when power is removed. The battery is on the system board.

System Board Battery

If the server no longer automatically displays the correct date and time, the system board battery that provides power to the real-time clock may need to be replaced. Under normal use, battery life is 5 to 10 years.

WARNING: The system board contains a lithium battery. There is a risk of fire and chemical burn if the battery is improperly handled. Do not disassemble, crush, puncture, or short external contacts, dispose of in water or fire, or expose the battery to temperatures higher than 60°C (140°F).

CAUTION: Static electricity can damage the electronic components of the server. Before beginning these procedures, be sure that you are discharged of static electricity by briefly touching a grounded (earthed) metal object. Refer to “Electrostatic Discharge Information” earlier in this chapter.
