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 Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments. Statement 1051
Warning Ultimate disposal of this product should be handled according to all national laws and
regulations. Statement 1040
To install an SFP module in your router:
Step 1 Read the “Safety Warnings” section on page 6-2 section and disconnect the power supply before you
replace any module.
Step 2 Slide the SFP into the router connector until it locks into position (see Figure 6-50).
Tip If the SFP uses a bale-clasp latch (see Figure 6-50), 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.
