NOTE: After installing a PSU, allow several seconds for the system to recognize the PSU and determine whether it is
working properly.
3. If the problem is not resolved, swap or replace the PSU with a known good PSU.
4. If none of the power supplies show a fault LED and the sleds do not power on, check the CMC for status messages. For
more information, see the Dell PowerEdge FX2 CMC User’s Guide at Dell.com/esmmanuals.
5. If the problem persists, see Getting Help.
Troubleshooting power supply unit mismatch
The PowerEdge FX2 chassis unit supports various power supply unit (PSU) models. Instances of PSU mismatch may occur
when mixing different PSU models in a system configuration.
Steps
1. The system checks for a PSU mismatch following an AC power cycle or when a replacement PSU is connected.
2. The LED indicator in the handle of the PSU flashes green several times then turns off, this sequence indicates that there is a
PSU mismatch.
NOTE: A critical alert message is generated in the chassis management controller (CMC) logs. The log provides
information on the PSU redundancy status and the log also indicates if the PSU is incompatible with the other installed
PSUs.
3. Replace the incompatible PSU with a known good PSU.
4. If the problem persists, see Getting Help.
Troubleshooting 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 are shipped with your product.
Ensure that the following conditions exist:
● System cover, sled blank(s), or expansion-card filler bracket(s) is not removed.
● Ambient temperature is not too high.
● External airflow is not obstructed.
NOTE:
To maintain optimum thermal conditions, ensure that there are no obstructions to airflow on the front and back
of the enclosure. The front and back of the enclosure must have at least 30 cm (12 inches) and 61 cm (24 inches) of
unobstructed space respectively.
● A cooling fan is not removed or has not failed.
● The expansion card installation guidelines are followed.
Troubleshooting cooling fans
Prerequisites
CAUTION:
The power supply units (PSUs) are hot swappable. Remove and replace only one PSU at a time in
a system that is turned on. Leave a failed PSU installed in the enclosure until you are ready to replace it.
Operating the system with a PSU removed for extended periods of time can cause the system to overheat.
Steps
1. Log in to the CMC web interface and identify the faulty fan. For more information, see the Dell PowerEdge FX2 CMC User’s
Guide at Dell.com/esmmanuals.
2. Open the system. See Opening The System.
