Troubleshooting Power Supplies
Problem
l System-status indicators are amber.
l Power-supply fault indicators are amber.
l Front-panel status LCD indicates a problem with the power supplies.
Action
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.
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 Power Supplies.
3. Ensure that the power supply is properly installed by removing and reinstalling it. See Power Supplies.
If the problem persists, see Getting Help.
Troubleshooting System Cooling Problems
Problem
l Systems management software issues a fan-related error message.
Action
Ensure that none of the following conditions exist:
l Ambient temperature is too high.
l External airflow is obstructed.
l Cables inside the system obstruct airflow.
l An individual cooling fan has failed. See Troubleshooting a Fan.
Troubleshooting a Fan
Problem
l System-status indicator is amber.
l Systems management software issues a fan-related error message.
l Display module LCD indicates a problem with the fan.
Action
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system.
Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the
computer and protecting against electrostatic discharge.
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.
