PS4210 Hardware Owner's Manual 5 Troubleshooting Your Array - Replace the power cable. If the problem is not resolved, or if the power supply's fault indicator is lit, see Contacting Dell on page v. 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 Removing a Power Supply and Cooling Module 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 Contacting Dell on page v. Array Cooling Problems Check for and correct any of the following situations: • Fan failures-review member status in the GUI or CLI messages indicating fan failure. Fan failures will require replacement of a power supply unit. • Empty drive bays (no drive or drive blank) or empty controller slot. • 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 Contacting Dell on page v. Control Module Failures 1. Check the control module status LEDs. See Interpreting Control Module LEDs on page 16 for more information. 2. Reseat the control module and wait for 30 seconds. See Replacing a Control Module on page 20. If the problem is not resolved, see Contacting Dell on page v. Faulty Hard Drives Check the hard drive indicators before removing the faulty drive from the array. Confirm that the drive in question is also identified as being faulty in the GUI, console log or monitoring log. • Remove the drive from the array and replace the drive as soon as possible.
