2 Turn off the system and disconnect it from the electrical outlet for at least one hour.
3 Reconnect the system to the electrical outlet and turn on the system.
4 Enter the System Setup program.
If the date and time are not correct in the System Setup program, replace the battery. See
"System Battery" in "Installing System Options."
If the problem is not resolved by replacing the battery, see "Getting Help."
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.
Troubleshooting Power Supplies
Problem
• System-status indicators are amber.
• Power-supply fault indicators are amber.
Action
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 came with the product.
1 Run the appropriate online diagnostics test. See "Using Server Administrator Diagnostics" in
"Running the System Diagnostics."
2 Locate the faulty power supply.
The power supply's fault indicator is lit. See "Power Indicator Codes" in "Indicators, Codes,
and Messages."
NOTICE:
You can hot-plug the power supplies. One power supply must be installed for the system to
operate. The system is in the redundant mode when two power supplies are installed. Remove and install
only one power supply at a time in a system that is powered on. Operating the system with only one
power supply installed for extended periods of time can cause the system to overheat.
3 Ensure that the power supply is properly installed by removing and reinstalling it. See
"Removing a Redundant Power Supply" and "Installing a Redundant Power Supply" in
"Installing System Options."
NOTE:
After installing a power supply, allow several seconds for the system to recognize the
power supply and to determine if it is working properly. The power indicator turns green to signify
that the power supply is functioning properly. See "Power Indicator Codes" in "Indicators, Codes,
and Messages."
