Battery
Use the following steps to replace the battery:
WARNING: There is a danger of explosion if the battery is incorrectly installed. For
your safety, never attempt to recharge, disassemble, or burn the old battery. Replace
only with the same or equivalent type recommended by the manufacturer. Dispose of
used batteries according to the manufacturer's instructions.
1. If the server is operating, log off all users, back up files, and power down the server.
2. Disconnect the power cord and any external cables connected to the server. If necessary,
label each one to expedite re-assembly.
WARNING: The power supply will continue to provide standby current to the HP server
until the power cord is disconnected.
3. Open the side panel.
4. Remove any accessory boards, if necessary, allowing access to the battery socket.
5. Remove the existing battery. Refer to Figure 5-3.
The battery is spring loaded into the mounting socket and held in place by a latching
mechanism. Press the release mechanism toward the outside of the mounting socket to
release the battery.
