Troubleshooting Your System
161
1 Identify the faulty power supply by the power supply's status indicator. See
"Power Indicator Codes."
CAUTION:
If troubleshooting a power supply mismatch error, replace only the
power supply with the flashing indicator. Swapping the opposite power supply to
make a matched pair can result in an error condition and unexpected system
shutdown. To change from a High Output configuration to an Energy Smart
configuration or vice versa, you must power down the system.
2 Reseat the power supplies by removing and reinstalling them. See
"Removing a Power Supply" and "Installing a Power Supply."
NOTE:
When 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 status indicator turns green to signify that the power supply is
functioning properly.
If the problem persists, replace the faulty power supply with the same type
of power supply.
3 If the problem persists, see "Getting Help."
Troubleshooting System Cooling Problems
CAUTION:
Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.
Ensure that none of the following conditions exist:
• System cover, cooling shroud, drive blank, memory-module blank, power-
supply blank, or back filler bracket is removed.
• Heat-sink blank is removed (in single-processor configurations).
• Ambient temperature is too high. See your Getting Started Guide for your
system’s operating temperature requirements.
• External airflow is obstructed.
• An individual cooling fan module is removed or has failed. See
"Troubleshooting a Fan."
