6.5 Ethernet ports
There are two 10/100/1000 Mbps Ethernet ports that use standard RJ45 Ethernet connectors.
The two RJ45 connectors on the POSYC are shown below:
Each of the two Ethernet ports has two LEDs. The first, distinguished by the letter A, indicates the communi-
cation speed of the port involved. It is a two-color LED (green / orange); according to the speed at which the
Ethernet port is communicating, the LED takes on a different color. The second, yellow, marked by the letter
B, indicates the state of activity of the gate itself, or if the gate is connected or if it is communicating.

Below is a table that summarizes the possible speed states of Ethernet port:
