Troubleshooting Power Supplies

2Turn off the system and disconnect it from the electrical outlet for at least one hour.

3Reconnect the system to the electrical outlet and turn on the system.

4Enter the System Setup program.

If the date and time are not correct in the System Setup program, replace the battery. See "System Battery" on page 115.

If the problem is not resolved by replacing the battery, see "Getting Help" on page 179.

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.

Problem

•System-status indicators are amber.

•Power-supply fault indicators are amber.

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

Action

1Locate the faulty power supply.

The power supply's fault indicator is lit. See "Power Indicator Codes" on page 19.

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 can cause the system to overheat.

2Remove the faulty power supply. See "Power Supplies" on page 71.
