PS6610 Hardware Owner's Manual 7 Troubleshooting Your Array • The array fault LEDs are lit. See Front-Panel Features and Indicators on page 1. • A constant scraping or grinding sound occurs when you access the hard drive. See Obtaining Technical Support and Customer Service on page v. 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 Dual Controller Configuration on page 16. If the LEDs are not solid green, see Control Module Features on page 15. • Make sure that all the cables are attached correctly. If the problem is not resolved, see Obtaining Technical Support and Customer Service on page v. 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. Note: 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 Remove a Power Supply Unit on 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. 40

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
