Ethernet Management Port
The Ethernet management port supports10/100/1000BASE-T Ethernet. It can autonegotiate to operate at any line speed (10, 100, 1000 Mbps); full and half duplex modes for 10 and 100 Mbps line speed, and only full duplex at 1000 Mbps. The Ethernet management port has an RJ-45 connector with an associated Link Status LED. Table B-15lists the 10/100BASE-T port pinouts.
