Troubleshooting Power Supply/Cooling Fan Module

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.

CAUTION: It is recommended that you turn off the host server before turning off the enclosure to prevent loss of data.

1Locate the faulty power supply and determine the status of the LEDs.

•If the AC power LED is not lit, check the power cord and power source into which the power supply is plugged.

•Connect another device to the power source to verify if it is working.

•Connect the cable to a different power source.

•Replace the power cable.

If the problem is not resolved, see "Getting Help" on page 57.

•If the DC power LED is not lit, verify that the power switch is turned on. If the power switch is turned on, see step 2.

•If the power supply’s fault indicator is lit, see "Getting Help" on page 57.

CAUTION: Power supply/cooling fan modules are hot-swappable. The enclosure can operate on a single power supply; however both modules must be installed to ensure proper cooling. A single power supply/cooling fan module can be removed from a powered-on enclosure for a maximum period of five minutes. Beyond that time, the enclosure may automatically shut down to prevent damage.
