Connecting the Switch Ports
SFP and SFP+ Tranceiver Module Ports
Use only Cisco SFP transceiver modules with the switch. For a list of supported modules, see the
Catalyst 3850 Switch Hardware Installation Guide. For detailed instructions on installing, removing,
and connecting to SFP transceiver modules, see the SFP and SFP+ transceiver modules 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.
Step 1
Hold the SFP tranceiver module on the sides, and
insert it into the SPF module slot on the switch until
you feel the connector snap into place.
Note Depending on the model of the switch you
are working with, the four SFP module slots
can be all 1-Gigabit SFP module slots or all
10-Gigabit SFP+ module slots. They can
also be a combination of a pair of SFP
modules slots on the left and a pair of SFP+
module slots on the right. SFP+ module slots
support both SFP and SFP+ modules.
Step 2
Connect an appropriate cable to the module port.
Step 3
Connect the other cable end to the other device.
