Troubleshooting Your System 161
Troubleshooting Power Supplies
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 without a power-supply blank installed in the PS2 power-supply bay can
cause the system to overheat.
1 Identify the faulty power supply by the power supply's status indicator. See
"Power Indicator Codes" on page 21.
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 supply by removing and reinstalling it. See "Removing a
Power Supply" on page 90 and "Replacing a Power Supply" on page 91.
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
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" on page 189.
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, power supply blank (in single
power supply configurations), or front or back filler panel is removed.
• FAN5 blank or heat sink blank is removed.
