Installation Guide for the Model FS509 Fast Ethernet Switch Rear Panel As illustrated in Figure 2-4, the rear panel has a full-duplex (FDX) and auto-duplex (AUTO) toggle switch, cooling fan, and a standard AC power receptacle.

Rear Panel of the Model FS509 Switch FDX/AUTO Duplex Toggle Switches Full-duplex mode is supported for all 10/100 Mbps ports (ports 1 through 8) and allows a port to transmit and receive data at the same time. Full-duplex operation applies only to point-to-point access (for example, when a switch is connected to a PC, a server, or another switch). Setting the toggle switch to AUTO on the 10/100 Mbps port enables the port to determine duplex mode automatically. In this mode, the 10/100 Mbps port operates in either full- or half-duplex mode, depending on the operating mode of the remote port. If supported by the remote node, the port will establish a 100 Mbps full-duplex link as the default. If the remote port cannot provide the proper signal to indicate its own capability, the 10/100 Mbps port on the switch will default to half-duplex mode. Because repeaters and hubs use a common collision domain for all communications and cannot communicate in full-duplex mode, the associated 10/100 Mbps port on the switch should be set to auto-duplex operation when connecting to these types of devices. Setting the toggle switch to FDX on the 10/100 Mbps port enables the port to determine the speed but will set the duplex mode to full-duplex. 2-6 Physical Description
