1000BASE-SX Fiber Ports

The Model FS509 switch has one 1000BASE-SX fiber port. This port operates at 1000 Mbps
full-duplex exclusively and provides a standard duplex SC connector for 62.5/125 m or
50/125 m multimode fiber optic cable. Figure 2-3 shows a fiber optic cable connection to a
duplex SC connector. The Link LED to the right of the 1000BASE-SX fiber port indicates whether
or not proper signaling is established with the remote port. For further information about fiber
optic cables and connectors, refer to Appendix B, "Connector Pin Assignments," and Appendix C,
"Cabling Guidelines."

Warning: Fiber optic equipment can emit laser or infrared light that might injure your
eyes. Never look into an optical fiber or connector port. Always assume that fiber optic
cables are connected to a light source.

Normal/Uplink Push Button

The Normal/Uplink push button on the front panel of the switch, as illustrated in Figure 2-1,
allows you to select uplink (MDI) or normal (MDI-X) wiring for port 8 on the Model FS509
switch. This port is configured for normal wiring to connect to a PC when the push button is in
the out position. When the push button is pressed in, this port is configured for uplink wiring to
connect to another switch or to a hub, using a straight-through twisted pair cable.
