Connecting to the 10/100/1000 Ports
Step 5
Grasp the SFP module between your thumb and index finger, and carefully remove it from the
module slot.
Step 6
Place the removed SFP module in an antistatic bag or other protective environment.
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 2-13
.) When connecting to switches or
repeaters, use a crossover cable. (See the
“Cable and Adapter Specifications” section on page B-3
for
cable-pinout descriptions.)

Connecting to an Ethernet Port
Note
When connecting to 1000BASE-T-compatible devices, be sure to use a twisted four-pair,
Category 5 cable.
