Removing SFP Modules
Follow these steps to remove an SFP from a Cisco 3800 series router:
Step 1 Disconnect all cables from the SFP.
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.
Caution The latching mechanism used on many SFPs locks the SFP into place when cables are connected. Do
not pull on the cabling in an attempt to remove the SFP.
Step 2 Disconnect the SFP latch. See Figure 45.
Note SFP modules use various latch designs to secure the module in the SFP port. Latch designs are not linked
to SFP model or technology type. For information on the SFP technology type and model, see the label
on the side of the SFP.

Tip Use a pen, screwdriver, or other small straight tool to gently release a bale-clasp handle if you cannot
reach it with your fingers.
Step 3 Grasp the SFP on both sides and remove it from the router.
