Connecting to the 10/100/1000 Ports

Connecting to the 10/100/1000 Ports

The switch module 10/100/1000 ports 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.

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 10BASE-T, 100BASE-TX or 1000BASE-T devices:

Caution To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling procedures.

Step 1 When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through cable to an RJ-45 connector on the front panel. (See Figure 2-15.) When connecting to switches or repeaters, use a crossover cable. (See the “Cable and Adapter Specifications” section on page B-4for cable-pinout descriptions.)
