Dell PowerEdge M630 Systems (VRTX Enclosure) Owner's Manual
Troubleshooting the NVRAM backup battery
Prerequisites
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 telephone service and support team.
Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that are
shipped with your product.
The battery maintains the server module configuration, date, and time information in the NVRAM when the server module 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 server module without a battery; however, the server module configuration information maintained by the battery in NVRAM is erased each time you remove power from the server module. Therefore, you must reenter the system configuration information and reset the options each time the server module boots until you replace the battery.
Steps
- Reenter the time and date through the System Setup.
- Remove the server module from the enclosure for at least one hour.
- Install the server module in the enclosure.
- Enter the System Setup.
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, see the Getting help section.
NOTE: If the server module is turned off for long periods of time (for weeks or months), the NVRAM may lose its system configuration information. This situation is caused by a defective battery.NOTE: Some software may cause the server module time to speed up or slow down. If the server module operates normally except for the time maintained by the System Setup, the problem may be caused by a software rather than by a defective battery.
