Checking the New Power Supply Installation
Checking the New Power Supply Installation
To complete the installation, turn each power supply on and observe its LEDs to verify that it is operating properly.
Step 1 Review the descriptions of the power supply LEDs on page 6.
Step 2 Check the following components to make sure 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
•When two supplies are present, the second cable is connected to a separate AC power source if possible.
Step 3 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.
Step 4 Turn the power supply ON () by turning the switch clockwise
If the power supply switch resists, it 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 two inches, then push the power supply firmly back into the slot. Do not slam the supply into the
Step 5 Verify that the output fail LED stays off.
•If the output fail LED goes on, move the power supply to the other bay if possible and turn the power switch ON (). If the LEDs go on properly when the supply is installed in the other bay, suspect a faulty backplane power connector.
•If the output fail LED goes on 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 goes 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.
•If the output fail LED lights on two supplies that are connected to separate AC sources, assume that an overvoltage or overtemperature condition is causing the power supplies to shut down.
If the power supply fails to operate properly after several attempts to initialize it, contact a service representative for assistance. If the power supply fails (and you need to order a replacement) and you did not record the type of power supply in your chassis, you will have to check the chassis in order to make this determination.
