Installing an SFP Module
Use the following procedure to install an SFP module:
Step 1 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.
Step 2

Push the module back into the slot until the latch engages. When fully inserted, only the band around the
Step 5
front of the SFP module should be visible.
Remove the plug from the SFP module optical bores and save the plug for future use.

Step 7 Attach the network interface fiber-optic cable, as described in the

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
OL-2485-20
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.
