3.3 Link/Activity LEDs
The Link/Activity LEDs on the front panel are associated with indi- vidual ports, indicating whether a device is detected on the other end and whether or not the port has been automatically partitioned off.
The LFH hub monitors each port on the hub to determine whether or not there is a device on the other end. If the cable is connected to a port and a link is detected, the LED will light; otherwise the LED will not light and the transmit and receive functions of the port will be disabled.
3.4 Partition LED
The yellow Partition LED is located on the front panel and labeled as PARTITION. When there are too many collisions received from a specific station(s), the hub will automatically partition it to prevent the data transmission from other ports to those specific ports. When this port is partitioned, the LED will be turned on.
