Action
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.
1 Run the appropriate online diagnostics test. See "Entering the System
2 Turn off the system and attached peripherals, and disconnect the system
from the electrical outlet.
3 Open the system. See "Opening and Closing the System" on page 70.
4 Locate the faulty power supply.
The power supply's fault indicator is lit. See "Power Indicator Codes" on
page 20.
NOTICE:
You can hot plug the power supplies. One power supply must be installed
for the system to operate. The system is in the redundant mode when two power
supplies are installed. Remove and install only one power supply at a time in a
system that is powered on. Operating the system with only one power supply
installed for extended periods of time can cause the system to overheat.
5 Ensure that the power supply is properly installed by removing and
reinstalling it. See "Replacing a Power Supply" on page 90.
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. See "Power Indicator Codes" on page 20.
