Step 3 Connect the other end of the power cords to an AC-power input source. If both

power supplies will be used, make sure they are on different circuits.

Step 4 Turn the power switches to the ON position.

Step 5 Verify power supply operation by looking at the front panel power supply LEDs:

The PS1 or PS2 LED is green when the power supply and fans are functioning normally.

The PS1 or PS2 LED is red when the power supply is not functioning normally. The on/off switch may be set to off while the power supply is plugged in, or the power supply may be defective and not providing DC power to the switch. There may also be a fan failure.

The PS1 or PS2 LED is off when there is no power supply installed.
