– Replace the power cable.
If the problem is not resolved, or if the power supply's fault indicator is lit, see
Power supply and cooling modules are hot-swappable.
Dell does not recommend hot-swapping a DC power supply module.
The array can operate on a single power supply; however, both modules must be installed to ensure proper
cooling. A single power supply and cooling module can be removed from a powered-on array for a maximum
of 5 minutes.
2. Reseat the power supply by removing and reinstalling it. See
on page 32.
After installing a power supply, allow several seconds for the array to recognize the power supply and to
determine if it is working properly.
If the problem is not resolved, see
Array Cooling Problems

• Fan failures–review member status in the GUI or CLI messages indicating fan failure. Fan failures will

• Ambient temperature is too high. See the Technical Specifications for the array in the Dell EqualLogic
PS4210 Series Array Installation and Setup Guide.
• External airflow is obstructed by cables or other items in the rack.
If the problem is not resolved, see
