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.
