2. Check that the fiber terminators are clean. You can clean the cable
plugs by wiping them gently with a clean tissue or cotton ball
moistened with a little ethanol. Dirty fiber terminators on fiber optic
cables will impair the quality of the light transmitted through the cable
and lead to degraded performance on the port.
3. Connect one end of the cable to the LC port on the switch and the
other end to the LC 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 Link LED on the switch
corresponding to the port to be sure that the connection is valid.
The 1000BASE-SX, 1000BASE-LX, 1000BASE-ZX fiber optic ports
operate at 1 Gbps, full duplex, with auto-negotiation of flow control. The
maximum length for fiber optic cable operating at Gigabit speed will
depend on the fiber type as listed under “1000 Mbps Gigabit Ethernet
Collision Domain” on page 4-6.
