Chapter 21 Connecting Gigabit Ethernet Network Modules 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.) Figure 21-2 Installing a GBIC into a Network Module NM-1GE GBIC EN RX TX LINK 72705 Step 2 Step 3 Release the side clips on the GBIC. 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.)
