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.
1 Identify the faulty power supply by the power supply's fault indicator. See
"Power Indicator Codes" on page 22.
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.
2 Reseat the power supply by removing and reinstalling it. See "Removing a
Power Supply" on page 154 and "Installing a Power Supply" on page 155.
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.
3 If the problem persists, see "Getting Help" on page 203.
