About Loop detection
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.
Press "LED DISPLAY CHANGE BUTTON" manually.
