Installing SFP Modules Note Cisco 3800 series routers do not support 1000Base-T SFP modules in the router's SFP slot. 1000Base-T connectivity is provided by the Gigabit Ethernet ports built into the router. Laser Safety Guidelines Optical SFPs use a small laser to generate the fiber-optic signal. Keep the optical transmit and receive ports covered whenever a cable is not connected to the port. Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Installing SFP Modules in Cisco 3800 Series Routers
OL-5968-01
Note
Cisco 3800 series routers do not support 1000Base-T SFP modules in the router’s SFP slot. 1000Base-T
connectivity is provided by the Gigabit Ethernet ports built into the router.
Laser Safety Guidelines
Optical SFPs use a small laser to generate the fiber-optic signal. Keep the optical transmit and receive
ports covered whenever a cable is not connected to the port.
Warning
Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable
is connected, avoid exposure to laser radiation and do not stare into open apertures.
Warning
Ultimate disposal of this product should be handled according to all national laws and regulations.
Installing SFP Modules
Follow these steps to install an SFP module in a Cisco 3800 series router:
Warning
Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable
is connected, avoid exposure to laser radiation and do not stare into open apertures.
Step 1
Slide the SFP into the router slot until it locks into position (see
Figure 44
).
Tip
If the SFP uses a bale-clasp latch (see
Figure 45
), the handle should be on top of the SFP module.

Caution
Do not remove the optical port plugs from the SFP until you are ready to connect cabling.
Step 2
Connect the network cable to the SFP module.
