3. Connect one end of the cable to the LC port on the switch and the
other end to the port on the other device. Since LC connectors are
keyed, the cable can be attached in only one orientation.

4. As a connection is made, check the green Link LED on the switch
corresponding to the port to be sure that the connection is valid.
The 100BASE-FX fiber optic transceiver operates at 100 Mbps, full
duplex. The 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber
optic transceivers operate at 1 Gbps, full duplex. The maximum length for
fiber optic connections will depend on the fiber type as listed under
“1000 Mbps Gigabit Ethernet Collision Domain” on page 4-8.
Connectivity Rules
When adding hubs (repeaters) to your network, pleas e follow the
connectivity rules listed in the manuals for these products. However, note
that because switches break up the path for connected devices into
separate collision domains, you should not include the switch or connected
cabling in your calculations for cascade length involving other devices.
