3.3 Link/Receive LEDs
The Link/Receive LEDs on the front panel are associated with indi-
vidual ports, indicating whether a device is detected on the other end.
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 Utilization % LEDs
The Utilization % LEDs is defined to indicate the current traffic utiliza-
tion of the network. This hub supports 6 LEDs to indicate different
traffic utilization levels.
The table below shows the different status indications of the Utilization
% LEDs:
10~20%
