Troubleshooting enclosure components
The following procedures describe how to troubleshoot the enclosure components.
Troubleshooting a wet enclosure
Prerequisites
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.
Steps
1. Turn off the system and attached peripherals.
2. Disconnect the power supplies from the PDU or electrical outlet.
CAUTION: Wait until all of the indicators on the power supplies turn off before proceeding.
3. Remove the following components from the system:
a. Sleds
b. Power supplies
c. I/O modules
d. Cooling fans
e. Cooling-fan bay
f. CMC module
g. PCIe modules
CAUTION: Air dry and do not use towels.
4. Let the system dry thoroughly for at least 24 hours.
5. Reinstall the components you removed in step 3.
6. Reconnect the power supplies to the PDU or electrical outlet and start up the system.
If the system does not start up properly, see Getting Help.
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
1. 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.
2. Reseat the PSU by removing and reinstalling it.
