Diagnostic Tests
The following tests are available from the switch’s front panel and via
Telnet. For details on how to use the switch’s front panel buttons and
how to access the
Test Menu from the front panel, refer to the section

Accessing the switch via Telnet provides a more detailed response indicating
the switch’s condition and allows the use of some commands which do not
have an equivalent front panel command.
