Loop Detection and Blocking Function
When a port causes a loop, the corresponding LED lights up in orange. In this case,
the port is automatically blocked (default setting: 60 seconds) to prevent a loop. If
the loop is not resolved, the port will be blocked again. Resolve the loop while the
port is blocked.
You can Switching Hub the loop detection and blocking function settings (OFF/
ON) by pressing and holding the LED display Switching Hub button for 10 seconds
or more, or by configuring on the configuration screen. For details about settings
on the configuration screen, refer to Section 4.5.6 of Operation Manual for Menu
Screens. When successfully switched, the Loop History mode LED is lit.
If you wish to turn off the Loop History LED display, turn the Switching Hub off and
on. Up to 64 saved loop history entries can be retained in the Switching Hub.
