Connecting to the Switched 100BaseFX Port

Warning Class 1 laser product.

Warning Avoid exposure to the laser beam.

Caution 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.

Note This section provides information and procedures for connecting to the 100BaseFX

port (A), which uses a duplex SC connector. For information and procedures for connecting

to the switch ﬁber-optic ports that use MT-RJ connectors, see the “Connecting to the

Switched 100-Mbps Fiber-Optic Ports” section on page 2-29.

You can connect the 100BaseFX port (A) to other 100BaseFX-compatible network devices,

such as servers, routers, and other switches. This port uses a duplex SC connector, and you

must provide the 50/125- or 62.5/125-micron multimode ﬁber-optic cable to connect this

port to the other 100BaseFX device.

The ﬁber-optic connections between the switch and the attached device can be as follows:

• If the switch port and the port on the attached device are conﬁgured for half-duplex

operation, the connection can be over distances of 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 over distances of up to 2 kilometers.

The default duplex mode of this port is half duplex. To change the duplex mode of this port

to full-duplex or full-duplex ﬂow control, use the switch manager, management console, or

SNMP. (See the “Changing the Port Settings” section on page 3-15 or the “Port

Conﬁguration Menu” section on page 4-44.)

Note Duplex-mode autonegotiation is not supported on the 100BaseFX ports.
