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 PSU configuration, ensure that both the PSUs are of the same type and
wattage.
5. Ensure that you use only PSUs with the Extended Power Performance (EPP) label on the back.

NOTE: After installing a PSU, allow several seconds for the system to recognize the PSU and
determine if it is working properly.
