Troubleshooting SC400 Series Components

This section contains basic troubleshooting steps for components inside the SC400 series expansion enclosures.

Troubleshooting Power Supply/Cooling Fan Modules

Use these steps to troubleshoot power supply/cooling fan modules.
1.
Check the status of the power supply/cooling fan module using the Dell Storage Client.
2.
Determine the status of the power supply/cooling fan module LEDs.

If the power supply/cooling fan module fault indicator is lit, the power supply/cooling fan has failed.
•
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 and check whether the device works.
– Connect the power cord to a different power source.
– Replace the power cord.
•
If the DC power LED is not lit, verify that the power switch is turned on.
3.
Reseat the power supply/cooling fan module by removing and reinstalling it.
NOTE: Allow several seconds for the expansion enclosure to recognize the power supply/cooling fan module and
determine its status.

Troubleshooting Hard Drives

Use these steps to troubleshoot hard drives.
1.
Check the status of the hard drive using the Dell Storage Client.
