14 1200-Watt AC-Input Power Supply Replacement Instructions

If you are replacing both power supplies, repeat Steps 1 through 4 for the second power
supply.

This completes the power supply replacement procedure.

Proceed to the “Checking the Installation” that follows to apply power and check the installation.

To complete the installation, turn the power supply on and observe the LEDs to verify that the power
supply is operating properly.

To check the installation, follow these steps:

Review the descriptions of the power supply LEDs on page 4.

Check the following components to make sure that they are secure:

•

Each power supply is inserted all the way into its bay, and the captive installation
screw is tightened.

•

All power supply cables are attached to the power receptacles and secured with their
spring clips.

•

At the AC power-source end of the power cable, the cables are securely attached to the
AC power, and the source power is within the range indicated on the power supply.

•

When two supplies are present, the second cable is connected to a separate AC power
source if possible.

Remove the tape (that you applied earlier) from the circuit breaker switch handle and
restore power by moving the circuit breaker handle to the on position.

Turn the power supply to the on (|) position by turning the switch clockwise one-quarter
turn. The AC OK LED and the FAN OK LED lights and stays lit. No other LEDs should
light.

If the power supply switch resists, the power supply is probably not fully inserted into the
bay. Turn the power switch fully counterclockwise to off (O), pull the power supply out
of the bay about 2 inches, and then push the power supply firmly back into the slot. Do
not force the supply into the slot; doing so can damage the connectors on the supply and
the backplane. Tighten the captive installation screw before proceeding.

Verify that the OUTPUT FAIL LED stays off.

•

If the OUTPUT FAIL LED lights, move the power supply to the other bay if possible,
and turn the power switch on (|). If the LEDs light properly when the supply is
installed in the other bay, suspect a faulty backplane power connector.

•

If the OUTPUT FAIL LED lights when the power supply is installed in the other bay,
suspect a power supply failure or an adverse environmental condition (the power
supply has detected an overvoltage or overtemperature condition and has shut down).

•

If two power supplies are installed and the OUTPUT FAIL LED lights on only on one
power supply, assume that the power supply or AC source (for that supply) is faulty.

•

If the OUTPUT FAIL LED lights on two supplies that are connected to the same AC
source, suspect that the AC source is faulty, or that an overvoltage or overtemperature
condition is causing the power supplies to shut down.
