Installation Guide for the Model SW510 and Model SW518 Ethernet Switches HDX/FDX/AUTO Duplex Toggle Switches Full-duplex mode is supported for all 10 Mbps or 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). Because repeaters and hubs use a common collision domain for all communications and cannot communicate in a full-duplex mode, the associated 10 Mbps port on the switch should be set to half-duplex operation when connecting to these types of devices. 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 operates in half-duplex mode. As illustrated in Figure 2-4 and Figure 2-5, one half-duplex (HDX) and full-duplex (FDX) toggle switch is assigned to each 10 Mbps port on a switch. On the Model SW510 switch, the 10 Mbps ports are ports 1 through 8; on the Model SW518 switch, the 10 Mbps ports are ports 1 through 16. The communication mode can be set to either half-duplex or full-duplex mode. One FDX and AUTO toggle switch is assigned to each 10/100 Mbps port on a switch. On the Model SW510 switch, the 10/100 Mbps ports are ports 9 and 10; on the Model SW518 switch, the 10/100 Mbps ports are ports 17 and 18.The communication mode can be set to either full-duplex or auto-duplex mode. 2-6 Physical Description
