Hub ID Indicator
Color: Green
Label: Hub ID
Function: Indicates Unit ID Setting.
In a stacked system, each hub unit has a unique ID. The Fast
EtherHub 3500 hub series is equipped with a function that
automatically sets the hub ID, freeing the user from this task.
The table below shows possible display combinations for the
hub unit’s ID LED indicators marked “1 2 4” and their
corresponding meaning. These LEDs display the binary
equivalent of the selected ID number (displayed left to right).
In normal operation, the LEDS turned ON display a steady
light; while in configuration mode, they blink.
