Statement 8 Installing Other Accessories on Cisco Network Modules Some Cisco network modules support a variety of additional modules, such as gigabit interface converters (GBICs) and small form-factor pluggable modules (SFPs). Installing and Removing GBICs To install a GBIC, perform the following steps: 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 125 Step 1 Step 2 (For optical GBICs) Confirm insertion of plugs into the SC connectors on the GBIC to prevent laser emissions. 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 2-18.)
