Troubleshooting power supply units

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 are shipped with your product.

Power source problems

1. Press the power button to ensure that your system is turned on. If the power indicator does not light
up when the power button is pressed, press the power-on button firmly.
2. Plug in another working device to ensure that the system board is not faulty.
3. Ensure that no loose connections exist.
For example, loose power cables.
4. Ensure that the power source meets applicable standards.
5. Ensure that there are no short circuits.
6. Have a qualified electrician check the line voltage to ensure that it meets the required specifications.

PSU problems

1. Ensure that no loose connections exist.
For example, loose power cables.
2. Ensure that the PSU handle or LED indicates that the PSU is working properly.
3. If you have recently upgraded your system, ensure that the PSU has enough power to support the
new system.
4. If you have a redundant power supply configuration, ensure that both the PSUs are of the same type
and wattage.
You may have to upgrade to a higher wattage PSU.
5. Ensure that you use only PSUs with the Extended Power Performance (EPP) label on the back.
6. Reseat the PSU.
NOTE: After installing a PSU, allow several seconds for the system to recognize the PSU and
determine if it is working properly.
