determines the speed at which packets are transmitted through the specific SDA-4S port.
For example, if the device to which the port is connected is running at 100 Mbps, the port
connection will transmit packets at 100 Mbps. Conversely, if the device to which the port
is connected is running at 10 Mbps, the port connection will transmit packets at 10 Mbps.
In addition, the SDA-4S ports support MDI/MDI-X automatic crossover, allowing
connection to straight-through or crossover cables.
