Dell PowerEdge FX2 and FX2s Enclosure Owner's Manual
Troubleshooting power supply units
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.
NOTE: Ensure that all PSUs are of the same rated output capacity, generation, and input voltage.
NOTE: The FX2 chassis supports only PSUs with a rated output capacity of 1100 W, 1600 W, 2000 W, or 2400 W.
Steps
- Locate the faulty PSU and check the indicators. The AC indicator on the PSU is green if AC power is available. The fault indicator on the PSU is amber if the PSU is faulty. If no indicators are lit, ensure that AC power is available from the PDU or electrical outlet, and the power cable is properly connected to the PSU.
- Reseat the PSU by removing and reinstalling
it.
NOTE: After installing a PSU, allow several seconds for the system to recognize the PSU and determine whether it is working properly.
- If the problem is not resolved, swap or replace the PSU with a known good PSU.
- 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.
- If the problem persists, see Getting Help.
