3 Remove the mezzanine cards. See the compute sled’s documentation for
more information.
4 Locate the NVRAM clear jumper on the system board.
5 Clear the NVRAM.
6 Close the sled.
7 If there is still a problem with the compute sled, remove and reinstall the
sled.
If the problem persists, see "Getting Help" on page 289.
Troubleshooting the System Battery
NOTE: If the system 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.
1 Re-enter the time and date through the System Setup program. See
"System Setup Options at Boot" on page 68.
2 Turn off the sled and remove it from the enclosure for at least one hour.
3 Reconnect the sled to the server enclosure and turn on the sled.
4 Enter the System Setup program.
If the date and time are not correct in the System Setup program, replace
the battery.
If the problem is not resolved by replacing the battery, see "Getting Help"
on page 289.
CAUTION: 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 came with the product.
If the problem is not resolved by replacing the battery, see "Getting Help"
on page 289.
NOTE: Some software may cause the system time to speed up or slow down. If the
system seems to operate normally except for the time kept in the System Setup
program, the problem may be caused by software rather than by a defective
battery.
