Figure 18 Installing an SFP Module

Step 5 Push the module back into the slot until the latch engages. When fully inserted, only the band around the

front of the SFP module should be visible.

Step 6 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 “Connecting ATM OC-3 Ports to the

Network” section on page 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.

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.

Statement 240

The module faceplate carries a Class 1 laser warning label. See Figure 19.
