Auto-negotiation is supported only when the communication speed is set to default. In addition, the communication speed cannot be set
to 10Mbps or 100Mbps. (For details, refer to the Industrial Managed Switch User's Manual.)
Do not connect the industrial managed switch with a device which communicates in half-duplex mode. If it is connected with such a
device, re-transmission is not executed when a collision occurs.
