Troubleshooting Power Supply Modules

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 array to
prevent loss of data.
1. Locate 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 module 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
• 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 module's fault indicator is lit, see
CAUTION: Power supply modules are hot-swappable. The array can operate on a single
power supply module; however both modules must be installed to ensure proper cooling. A
single power supply module can be removed from a powered-on array for a maximum period
of five minutes. Beyond that time, the array may automatically shut down to prevent damage.
2. Reseat the power supply module by removing and reinstalling it.
NOTE: After installing a power supply module, allow several seconds for the array to recognize
the power supply module and to determine if it is working properly.
