Troubleshooting Power Supplies
1
Identify the faulty power supply by the power supply's fault indicator.
See "Power Indicator Codes" on page 20.
CAUTION:
At least one power supply must be installed for the system to operate.
Operating the system with only one power supply installed for extended periods of
time can cause the system to overheat.
2
Reseat the power supply by removing and reinstalling it. See "Power
Supplies" on page 88.
NOTE:
After installing a power supply, allow several seconds for the system
to recognize the power supply and to determine if it is working properly. The
power indicator turns green to signify that the power supply is functioning
properly.
If the problem persists, replace the faulty power supply.
3
If the problem persists, see "Getting Help" on page 177.
Troubleshooting System Cooling Problems

product.
Ensure that none of the following conditions exist:
•
System cover, cooling shroud, or front or back filler panel is removed.
•
Ambient temperature is too high.
•
External airflow is obstructed.
•
Cables inside the system obstruct airflow.
•
