Diagnostics
Hardware diagnostics provide you with software tools for diagnosing hardware-related
problems on Omni Switch/Router switching modules. These diagnostics allow you to test
switching modules off-line during network down time.
The Omni Switch/Router have a variety of switching modules interconnected by a frame
backplane and a management backplane. When a hardware failure occurs, the problem may
be related to a number of different failures. As part of a systematic troubleshooting proce-
dure, you can use the built-in diagnostic software to test basic connectivity and functionality.
The diagnostic software includes two basic types of tests: static tests and port tests. Static tests
verify the basic functions of memory and control/status registers of submodules. Port tests
check for data packet processing functions.
You can run the tests individually or sequentially. Diagnostic software also provides an option
that allows you to run all the tests in one session (exception: WSX modules require power
recycle after static test). The diagnostic tests performed vary, depending on the switching
module type under test.
♦ Important Note ♦
For Release 4.4 and later, the Omni Switch/Router is
factory-configured to boot up in CLI (Command Line
Interface) mode, rather than in UI (User Interface)
mode. Because Hardware Diagnostics are supported
only in UI mode, you must change from CLI mode to
UI mode to run Hardware Diagnostics. See Chapter 4,
“The User Interface” for information on changing from
CLI mode to UI mode.
