Dell R805 manual Troubleshooting Power Supplies, Troubleshooting System Cooling Problems

Page 77

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.

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.

•Front-panel status LCD indicates a problem with the power supplies.

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.

2.Locate the faulty power supply.

The power supply's fault indicator is lit. See Power Indicator Codes.

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 for extended periods of time with only one power supply installed, without a power supply blank installed, can cause the system to overheat.

Remove the faulty power supply. See Removing a Power Supply.

3. Ensure that the power supply is properly installed by removing and reinstalling it. See Replacing a Power Supply.

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.

4.Check the indicators to see if the problem is resolved. If not, remove the faulty power supply. See Removing a Power Supply.

5.Install a new power supply. See Replacing a Power Supply.

If the problem persists, see Getting Help.

Troubleshooting System Cooling Problems

Problem
