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:
•
•
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
repeaters, use a crossover cable. (See the
cable-pinout descriptions.)

Let the ports autonegotiate both speed and duplex.
Set the port speed and duplex parameters on both ends of the connection.
