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). The default setting is ON.
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.
Two types of Base modes
The mode at the start is called “Base mode.”
There are two types of Base modes: Status mode (factory default setting) and ECO mode.
In the Status mode, you can check the terminal connection status by checking Port LED (left) lamps.
In the ECO mode, all Port LED lamps are off.
You can switch between the Status mode and ECO mode by command setting.
