The battery maintains the sled configuration, date, and time information in the NVRAM when the sled is turned off. You mayneed to
replace the battery if anincorrect 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

5

If the date and time are not correct in the System Setup, replace the battery. If the problem is not resolved by replacing the battery,
seetheGettinghelpsection.
NOTE:
If the sled is turned off for long periods of time (for weeks or months), the NVRAM may lose its system configuration
information. Thissituationiscausedbyadefectivebattery.
