RJ-45 Connector
Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.
Statement 1021
Note
Always keep caps and plugs on the fiber-optic connectors on the cable and the switch when they are not
in use.
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments.
Statement 1051
SC Connector
The SC connector, shown in
Figure 11
, is used to connect fiber-optic module ports or transceivers with
the external SMF or MMF network.
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments.
Statement 1051
Note
Make sure that the optical connectors are clean before making the connections. Contaminated connectors
can damage the fiber and cause data errors.
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,
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 made.
