Troubleshooting Power Supplies
CAUTION: The power supplies are hot swappable. Remove and replace only one power supply at a time in a
system that is turned on. Leave a failed power supply installed in the enclosure until you are ready to replace it.
Operating the system with a power supply removed for extended periods of time can cause the system to overheat.
1. Locate the faulty power supply and check the indicators. The power supply's AC indicator is green if AC power is
available. The power supply's fault indicator is amber if the power supply is faulty. If no indicators are lit, ensure
that AC power is available from the PDU or electrical outlet, and that the power cable is properly connected to the
power supply.
2. Reseat the power supply by removing and reinstalling it.
NOTE: After installing a power supply, allow several seconds for the system to recognize the power supply
and determine whether it is working properly.
3. If the problem is not resolved, swap or replace the power supply with a known good power supply.
4. If none of the power supplies show a fault LED and the server modules do not power on, check the LCD display or
CMC for status messages. For more information, see the
Dell Chassis Management Controller for Dell PowerEdge
VRTX User’s Guide
at dell.com/esmmanuals.
5. If the problem persists, see Getting Help.
Troubleshooting Blower Modules
CAUTION: The blower modules are hot swappable. Remove and replace only one blower module at a time in a
system that is turned on. Operating the system without all four blower modules for extended periods of time can
cause the system to overheat.
1. Locate the faulty blower module using the back-panel blower module indicators.
2. Remove the blower module.
3. Examine the server modules for debris. If debris is present, carefully remove it.
4. Reseat the faulty blower module.
5. If the problem is not resolved, install a new blower module.
6. If the new blower module does not operate, see Getting Help.

1. Check the LCD screen for error messages indicating a defective system battery.
2. Turn off the system and disconnect it from the electrical outlet.
