Cisco Catalyst 6807-XL User Manual

Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the
dielectric properties of the materials used in their construction. Always ground the cables (especially in
new cable runs) to a suitable and safe earth ground before connecting them to the module.
Caution
To comply with GR-1089 intrabuilding and lightning immunity requirements, you must use a foil
twisted-pair (FTP) cable that is properly grounded at both ends.
Caution
SC Connector
The SC connector is used to connect fiber-optic module ports or transceivers with the external SMF or MMF
network.
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams
or view directly with optical instruments. Statement 1051
Warning
Make sure that the optical connectors are clean before making the connections. Contaminated connectors
can damage the fiber and cause data errors.
Note
Figure 36: SC Fiber-Optic Connector
Always insert the network connector completely into the socket. A secure connection is especially important
when you are establishing a connection between a module and a long-distance (1.24 miles) (2 km) network,
or a module and a suspected highly attenuated network. If the link LED does not light up, try removing the
network cable plug and reinserting it firmly into the module socket. It is possible that dirt or skin oils have
accumulated on the plug faceplate (around the optical-fiber openings), generating significant attenuation and
reducing the optical power levels below threshold levels so that a link cannot be established.
Use extreme care when removing or installing connectors so that you do not damage the connector housing
or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected
components to prevent contamination. Always clean fiber connectors before installing them.
