Invisible laser radiation may be emitted from the aperture ports of the
100BASE-FX single-mode supervisor engine module. Avoid exposure and do not
stare into open apertures.
Avoid exposure to the laser beam.
Do not remove the rubber plugs from the fiber-optic port or the rubber caps from
the fiber-optic cable until you are ready to connect the cable. The plugs and caps
protect the fiber-optic port and cable from contamination and ambient light.
You can connect the 100BASE-FX ports to other 100BASE-FX-compatible
network devices, such as servers, routers, and other switches. These ports use a
duplex SC connector, and you must provide the 50/125- or 62.5/125-micron
multimode fiber-optic cable to connect these ports to other 100BASE-FX devices.
The fiber-optic distances between the switch and the attached device follow.
If the switch port and the port on the attached device are configured for
•
half-duplex operation, the connection can be up to 412 meters.
If the switch port and the port on the attached device are configured for
•
full-duplex operation, the connection can be up to 2 kilometers.
Speed and duplex-mode autonegotiation is not supported on the 100BASE-FX
ports.
To connect a switch 100BASE-FX port to another 100BASE-FX device, follow
these steps:
Remove the rubber plugs from the port and the rubber caps from the cable
connectors.
Connect one end of the fiber-optic cable to the 100BASE-FX port on the switch,
as shown in
Figure
