Removing the system battery If the server no longer automatically displays the correct date and time, you may need to 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 battery: 1. Power down the server (on page 27). 2. Extend or remove the server from the rack ("Extending the server from the rack" on page 27). 3. Remove the access panel ("Removing the access panel" on page 28). 4. Locate the battery ("Internal components" on page 12). It might be necessary to remove expansion boards (on page 46) from and around slot 9 to access the battery. 5. Remove the battery. To replace the component, reverse the removal procedure. Run the RBSU to configure the server after replacing the battery. See the HP ROM-Based Setup Utility User Guide on the Documentation CD for more detailed information. Operations 31
