Connecting to a 100BASE-FX Port
• 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.
Note 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:
Step 1 Remove the rubber plugs from the port and the rubber caps from the cable
connectors.
Step 2 Connect one end of the fiber-optic cable to the 100BASE-FX port on the switch,
as shown in
Figure 2-18 .

Step 3 Connect the other end of the cable to the 100BASE-FX port of the other device.
Step 4 The port LED comes on when both the switch and the connected device have
established link.
The port LED is amber while the STP discovers the topology and searches for
loops. This takes about 30 seconds, and then the port LED turns green.
If the port does not come on, the device at the other end might not be turned on,
or there might be a cable problem or a problem with the adapter installed in the
attached device. See Chapter 3, “Troubleshooting,” for solutions to cabling
problems.
