Installing SFP Modules in
Cisco 3800 Series Routers
This document describes how to install optional small-form-factor pluggable (SFP) modules in
Cisco 3800 series integrated services routers to provide optical Gigabit Ethernet connectivity. It contains
the following sections:
• Installing SFP Modules, page 70
• Removing SFP Modules, page 71
The SFP module installs into a slot on the router’s rear panel. When selected in Cisco IOS software, it
is assigned port gigabitethernet 0/0. The default is for the built-in RJ-45 1000Base-T connector to be
active on this port.
Only SFP modules certified by Cisco are supported on Cisco 3800 series routers. Table 6 lists supported
SFPs.
Tip Use the show controller command at the Cisco IOS prompt to determine whether you are using an SFP
certified by Cisco.
