Loss of Array Connections

• Verify that the control module port link status LED and the control module status LED are solid
green for one of the ports in each pair as described in the

• Make sure that all the cables are attached correctly.
If the problem is not resolved, see Obtaining Technical Support and Customer Service on

Loss of External Connections

• Verify that the cables are connected to the correct Ethernet port and, if applicable, to management
ports before troubleshooting any external devices.
• Make sure that the power cables are securely attached to the power supply modules on your array.

Power Supply Failure

1. Locate the faulty power supply and determine the status of the LEDs.
If the power LED is not lit, check the power cord and power source into which the power supply
is connected.
– 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, or if the power supply's fault indicator is lit, contact your PS Series
support provider.
Power supply and cooling modules are hot-swappable.
Dell does not recommend hot-swapping a DC power supply module.
Note:
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 pow-
ered-on array for a maximum of 5 minutes.
2. Reseat the power supply by removing and reinstalling it. See
page 32.
Note: 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, contact your PS Series support provider.

Array Cooling Problems

Check for and correct any of the following situations:
• Fan failures. Review the member status in the GUI or CLI messages indicating fan failure. Fan
failures require replacing a power supply unit.
• Empty drive bays or empty controller slot.
