Fdx/Col Leds; 100 M Led; Table 5-1: Led Signals - Ovislink Live-FSH16T User Manual

While the port is transmitting or receiving data, you will see a blinking green light.
If you've made a connection but the Link/Rx LED does not light up as expected, you
should check whether the RJ-45 connectors are damaged, or the cable type or pin-out is not
correct, or the cable length exceeds the 100 meter limit.

FDX/Col LEDs

FDX/Col LED shows the transmission mode as well as the presence of collision on the
network.
When in full-duplex transmission mode, FDX/Col LED gives forth a solid yellow light.
When in half-duplex mode, it will be off. But, when in half-duplex mode, there are two or
more end stations on the same network segment attempting to transmit data at the same
time, a collision occurs. If there is a collision detected on specific network segment, the
corresponding FDX/Col LED shows a blinking yellow light. When a collision occurs, all
of the stations involved will recognize the collision, wait a random amount of time, and
retransmit.
FDX/Col LED status is summarized as follows:
ON : Transmission in full-duplex.
OFF: Transmission in half-duplex.
Blinking: Collision detected.

100 M LED

100M LED showing a solid red light indicates that the line speed going through that
specific 10/100 Mbps port is operating at 100Mbps mode. If the transmission speed
operates only at 10 Mbps, it is off.
