Gigabit Ethernet Network Modules
Step 1
Hold down the clips on the side of the GBIC while inserting the GBIC into the GBIC slot in the network
module faceplate. (See
Figure 21-2
.)

Step 2
Release the side clips on the GBIC.
Step 3
Connect the Gigabit Ethernet network module to the network. (See
Figure 21-4
.) If installing the GBIC
in an uninstalled network module, install the network module (see
Chapter 2, “Installing Cisco Network
Modules in Cisco Access Routers”
) before connecting the network module to the network.
Laser Safety Guidelines
Optical GBICs use a small laser to generate the fiber-optic signal. Keep the transmit port covered
whenever a cable is not connected to the port.
The module faceplate carries a Class 1 laser warning label. (See
Figure 21-3
.)

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.
