Connecting the Switch Ports
SFP-Module Ports
Step 1 Hold the SFP module on the sides, and insert it into
the switch slot until you feel the connector snap into
place.
Step 2 Connect an appropriate cable to the module port.
Step 3 Connect the other cable end to the other device.
Use only Cisco SFP modules with the switch. For a list of supported modules, see the release notes on
Cisco.com. For detailed instructions on installing, removing, and connecting to SFP modules, see the
SFP module documentation.
Verify Port Connectivity
After you connect a device to the switch port, the port LED turns amber for about 30 seconds while the
switch establishes a link. The LED turns green when the switch and the attached device have a link. If the
LED is off, the device might not be turned on, there might be a cable problem, or there might be a
problem with the adapter installed in the device.
