The battery maintains the sled configuration, date, and time information in the NVRAM when the sled is
turned off. You may need to replace the battery if an incorrect time or date is displayed during the boot
routine.
You can operate the sled without a battery; however, the sled configuration information maintained by
the battery in NVRAM is erased each time you remove power from the sled. Therefore, you must re-enter
the system configuration information and reset the options each time the sled boots until you replace the
battery.
Steps
1. Re-enter the time and date through the System Setup.
2. Turn off the sled using the operating system commands or the CMC.
3. Remove the sled from the enclosure for at least one hour.
4. Install the sled in the enclosure.
