Chapter 11 Connecting ATM Network Modules ATM OC-3 Network Modules Installing an SFP Module Use the following procedure to install an SFP module: Step 1 Step 2 Step 3 Step 4 Attach an ESD-preventive wrist strap to your wrist and between yourself and an unpainted chassis surface. Verify that you have the correct SFP module for your installation. • Check the part number and distance information on the SFP module label. • Alternatively, if the distance information is not on the label, use the show contr pos x/y command to display the information after the SFP module is installed. Align the SFP module with the slot so that the label is facing away from the handle. Holding the module at the latching band (with your thumb and forefinger), insert the SFP module into the slot on the SFP port. See Figure 11-18.

When fully inserted, only the band around the front of the SFP module should be visible. Remove the plug from the SFP module optical bores and save the plug for future use. Attach the network interface fiber-optic cable, as described in the "Connecting ATM OC-3 Ports to the Network" section on page 11-9. Laser Safety Guidelines ATM OC-3 network modules use a small laser to generate the fiber-optic signal. Keep the transmit port covered whenever a cable is not connected to it. The module faceplate carries a Class 1 laser warning label. See Figure 11-19. OL-2485-20 Cisco Network Modules Hardware Installation Guide 11-13
