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

Follow these steps to install an SFP module in a Cisco ISR 4451-X:

Step 2 Slide the SFP into the router connector until it locks into position (see Figure 6-27).

Tip If the SFP uses a bale-clasp latch (see Figure 6-27), the handle should be on top of the SFP module.
