Observe the behavior of the red OUTPUT FAIL LED on the power supply faceplate after you apply power to the unit. This LED should flash on momentarily, then go off and remain so.

Set the rotary power switch on the newly-installed power supply to the ON position.

Observe the behavior of the green AC INPUT OK LED on the power supply faceplate for the following conditions:

Adding, Removing, or Replacing an AC-Input Power Supply

•The source end of the AC power cable is properly connected to the main source AC circuit breaker.

•The main source AC circuit breaker servicing the AC-input power supply is ON.

•The source AC voltage is within the range specified on the power supply faceplate.

•When two AC-input power supplies are installed, each power cord is connected to a separate AC power source.

Each AC power source must be on a dedicated circuit rated at 20A (for North America) or 10 or 16A (for the International area).

Step 3

•The AC INPUT OK LED illuminates if the source AC voltage is within the proper operating range (see the label on the power supply faceplate).

•If the green AC INPUT OK LED fails to illuminate, determine if

(a)The source AC circuit breaker is on.

(b)The source AC power cord is securely connected from the source AC circuit breaker to the AC receptacle on the power supply faceplate.
