●Loop detection/shutoff function and loop history function
Turns on the port LED with a 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 down.
During loop is occurring, or if loop has occurred within the latest 3 days, LOOP
HISTORY LED blinks to notify this.
It is possible to switch loop detection setting (OFF/ON) by using a console cable
(for detail, see the attached CD-ROM) or by pressing "LED DISPLAY CHANGE
BUTTON" for 10 seconds or more. (The default setting is ON.) When it is switched
successfully, LOOP HISTORY LED lights up and setting is complete.
If you wish to clear loop detection history, turn OFF once the power supply of the
Switching Hub and turn it ON again.
Then, loop detection history is deleted.
The Switching Hub can hold up to 64 loop history logs.
