Dell E05S001 Troubleshooting Power Supplies, Troubleshooting System Cooling Problems

Troubleshooting Power Supplies

CAUTION: At least one power supply must be installed for the system to operate. Operating the system with only one power supply installed for extended periods of time can cause the system to overheat.

1Identify the faulty power supply by the power supply's fault indicator. See "Power Indicator Codes" on page 21.

2Reseat the power supply by removing and reinstalling it. See "Removing a Power Supply" on page 85 and "Installing a Power Supply" on page 87.

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.

If the problem persists, replace the faulty power supply.

3If the problem persists, see "Getting Help" on page 185.

Troubleshooting System Cooling Problems

•Ambient temperature is too high. See your Getting Started Guide for your system’s operating temperature requirements.

•External airflow is obstructed.
