Dell MD1400 manual Troubleshooting enclosure cooling problems

Page 33

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.

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 PSU’s fault indicator is lit, see Getting Help.

CAUTION: Power supply unit or 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 unit or 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.

2.Reseat the power supply by removing and reinstalling it. See AC power supply unit or cooling fan module.

NOTE: After installing a PSUs, allow several seconds for the enclosure to recognize the PSUs and to determine if it is working properly.

If the problem is not resolved, see Getting Help.

3.If all LEDs on the PSUs or cooling fan module are off and if the enclosure is powered on, you must update the firmware. For information about updating the firmware, see Dell Update Package at dell.com/support.

Troubleshooting enclosure 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 came with the product.

Ensure that none of the following conditions exist:

Enclosure cover or hard disk drive blank is removed.

Ambient temperature is too high. See Technical specifications.

External airflow is obstructed.

The power supply unit or cooling fan module is removed or has failed. See Troubleshooting power supply unit or cooling fan module.

If the problem is not resolved, see Getting Help.
