Hub ID Indicators

Color: Green

Label:

Function: Indicates Unit ID Setting

In a stacked system, each hub unit has a unique ID. The EtherHub 1500 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 8" 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.

Port Status Indicators

There are 17 pairs of port status LED indicators. Each pair consists of a PARTITION/DISABLE LED (top row) and LINK/TRAFFIC LED (bottom row). Each pair (or column) has a label referring to the port number the LEDs monitor. For example, the port status LED pair labeled ALT monitors the optional port found at the rear panel (labeled ALT PORT). The other 16 pairs are for the RJ-45 ports on the front panel of the hub.
