Installing SFP Modules
This section describes how to install optional small-form-factor pluggable (SFP) modules in
Cisco ISR 4451-Xs to provide optical Gigabit Ethernet connectivity. There are four SFP slots in the
Cisco ISR 4451-X.
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 Cisco ISR 4451-Xs. Table 6-3 lists supported
SFPs on Cisco ISR 4451-Xs.
See Cisco Transceiver Modules Compatibility Information for compatibility issues.
