CAUTION: If troubleshooting a power supply mismatch error, replace only the power supply with the flashing indicator. Swapping the opposite power supply to make a matched pair can result in an error condition and unexpected system shutdown. To change from a High Output configuration to an Energy Smart configuration or vice versa, you must power down the system.
2Reseat the power supply by removing and reinstalling it. See "Removing a Power Supply" and "Replacing a Power Supply."
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 status indicator turns green to signify that the power supply is functioning properly.
If the problem persists, replace the faulty power supply with the same type of power supply.
3If the problem persists, see "Getting Help."
