Replacing an AC Power Supply
1
Turn the On/Off switch to the “Off” position on the power supply.
If the dual power supply option is installed, the working power supply will
continue to supply sufficient power to keep the system operational while
you replace the failed power supply.
2
Disconnect the AC power cord. Release the power cord bale and pull the
cord from the AC power cord module on the power supply.
