1.4.3. Loop detection function
Turns on the port LED with an orange light when a loop occurs in the
corresponding port. At this time, the relevant port automatically shuts down
(default setting: 60 sec.) to prevent loop from occurring. If the loop is still not
removed, the port will shut down again. Remove the loop while the port is
shut off.
The loop detection/shut-off function can be switched on/off by keeping
pressing the LED display switch button for more than 10 seconds or by
setting in the configuration menu. For details on the configuration menu,
refer to 4.7.8. If switching properly takes place, LOOP HISTORY LED turns on
to complete switchover.
The loop history can be reset by powering off the Switching Hub and then
on.
