Troubleshooting Your Array - Dell EqualLogic PS4210 Hardware Owner's Manual

5 Troubleshooting Your Array

Safety First—For You and Your Array
Many repairs may be done only by a certified service technician. You should perform troubleshooting and simple
repairs only 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.
Determining Service Tag Information
Each array has a service tag with a number. You might need to provide this information to customer support
when you contact us. The service tag label is visible on the front of the array, on the right bezel latch block.
Obtaining Component Diagnostics
You can collect diagnostic information for one or more members of a PS Series group through the Group
Manager GUI or the CLI. See the Dell EqualLogic Group Manager Administrator's Manual or the
Dell EqualLogic Group Manager CLI Reference Guide for more information.
Array Startup Failure
If your system halts during startup, check the following areas:

one of the ports in each pair as described by the vertical port failover section of this document. If the LEDs

• 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 con-
nected.
