The server comes with a system battery (Panasonic BR2032) installed on the management module,
which supplies power to the real-time clock and has a lifespan of 5 to 10 years. If the server no longer
automatically displays the correct date and time, you might need to replace the battery. As a best
practice, use the Panasonic BR2032 battery to replace the old one.
NOTE:
The BIOS will restore to the default settings after the replacement. You must reconfigure the BIOS to
have the desired settings, including the system date and time. For more information, see the BIOS
user guide for the server.
