Installation Guide for the Model FS516 Fast Ethernet Switch Rear Panel As illustrated in Figure 2-3, the rear panel has a full-duplex (FDX) toggle switch, an auto-duplex (AUTO) toggle switch, a standard AC power receptacle, and fans for cooling. 1 2 3 AUTO FDX - Enable port to determine duplex mode automatically Force port to operate at Full Duplex and Half Duplex mode only 10/100 Mbps 1 81 8 FDX AUTO 100-240 VAC 50-60 Hz 0.5A 8236FA Key: 1 = FDX and AUTO duplex toggle switches 2 = Fans 3 = AC power outlet Figure 2-3. Rear Panel of the Model FS516 Switch FDX/AUTO Duplex Toggle Switches Full-duplex mode is supported for all 10/100 Mbps ports and allows the 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 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 Mbps port on the switch should be set to auto-duplex operation when connecting to these types of devices. As illustrated in Figure 2-3, one full-duplex (FDX) and auto-duplex (AUTO) toggle switch is assigned to each 10/100 Mbps port on the Model FS516 switch. The communication mode can be set to either full-duplex or auto-duplex mode. 2-4 Physical Description
