Using System Diagnostics
If you experience a problem with your system, run the system diagnostics before contacting Dell for
technical assistance. The purpose of running system diagnostics is to test your system hardware without
requiring additional equipment or risking data loss. If you are unable to fix the problem yourself, service
and support personnel can use the diagnostics results to help you solve the problem.
Dell Online Diagnostics
Dell Online Diagnostics, a stand-alone suite of diagnostic programs or test modules, allows you to run
diagnostic tests on the systems in a production environment, and helps you ensure maximum uptime of
your systems. Online Diagnostics allows you to run diagnostic tests on chassis and storage components
such as hard drives, physical memory, and network interface cards (NICs). You can use the graphical user
interface (GUI) or the command line interface (CLI) to run diagnostic tests on the hardware that Online
Diagnostics discovers on your system. For information about using diagnostics, see the Dell Online
PowerEdge Diagnostics User’s Guide under Software → Serviceability Tools, at dell.com/support/
manuals.
Dell Embedded System Diagnostics
NOTE: Also known as Enhanced Pre-boot System Assessment (ePSA) diagnostics.
The embedded system diagnostics provides a set of options for particular device groups or devices
allowing you to:
• Run tests automatically or in an interactive mode
• Repeat tests
• Display or save test results
• Run thorough tests to introduce additional test options to provide extra information about the failed
device(s)
• View status messages that inform you if tests are completed successfully
• View error messages that inform you of problems encountered during testing
When To Use The Embedded System Diagnostics
If a major component or device in the system does not operate properly, running the embedded system
diagnostics may indicate component failure.
