Installing and Removing SFP Modules
This section describes how to install optional small-form-factor pluggable (SFP) modules in the router to
provide optical Gigabit Ethernet connectivity.
The SFP module installs into a slot on the router rear panel. When selected in Cisco IOS software, it is assigned
port
gigabitethernet 0/0/0
. The default is the built-in RJ-45 1000Base-T connector, which is enabled on this
port.
Only SFP modules certified by Cisco are supported on the routers.
