Step 4
Grasp the SFP module between your thumb and index finger, and carefully remove it from the module slot.
Step 5 For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical
interfaces clean.
Step 6 Place the removed SFP module in an antistatic bag or other protective environment.

Note
The router 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.
