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 came with the 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

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.
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.
