Connecting to 10/100 and 10/100/1000 Ports
The switch 10/100/1000 ports automatically configure themselves to operate at the speed of attached devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce performance or result in no linkage.
Warning Do not connect or disconnect cables to the ports while power is applied to the switch or any device on the network because an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed from the switch and cannot be accidentally be turned on, or verify that the area is nonhazardous before proceeding. Statement 1070
To maximize performance, choose one of these methods for configuring the Ethernet ports:
•Let the ports autonegotiate both speed and duplex.
•Set the port speed and duplex parameters on both ends of the connection. Follow these steps to connect to
