CAUTION:
Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or

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 supply unit from the sled. Therefore, you must reenter the system configuration
information and reset the options each time the sled boots until you replace the battery.
Steps
1. Reenter 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.
5. Turn on the sled.
6. Enter the System Setup.
