Diagnostics Push Button
The Diagnostics push button initiates the self-diagnostics test to determine the status of the system
components of the switch. The diagnostic test will automatically start when the system is powered on.
To start the diagnostic test after the switch has started operation, press the Diagnostics push button for
two seconds and then release.
After the self-diagnostic test starts, it will continue until all of the components of the ports are tested.
On completion of the diagnostic testing process, the LEDs will continue to blink (refer to Table 2-3).
This blinking indicates the corresponding port components that have failed. The blinking will
continue until the failed port has been repaired.
