NETGEAR FS102 Normal/Uplink Push Button, Rear Panel, FDX/AUTO Duplex Toggle Switches, 8901FA

Normal/Uplink Push Button

The Normal/Uplink push button on the front panel of the switch allows you to select uplink (MDI) or normal (MDI-X) wiring for either of the Ethernet ports on the Model FS102 switch, port 4 on the Model FS104 switch, or port 8 on the Model FS108 switch. These ports are configured for normal wiring to connect to a PC when the push button position is out. When the push button is pressed in, these ports are configured for uplink wiring to connect to another switch or to a hub, using a straight-through twisted pair cable.

Rear Panel

The rear panel of the Model FS102/FS104/FS108 switch has full-duplex (FDX) and auto-duplex (AUTO) toggle switches and a power adapter receptacle for the supplied power adapter.

FDX - Force port to operate at Full Duplex and Half Duplex mode.

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 of operation, the 10/100 Mbps port operates in either full- or half-duplex, depending on the operating mode of the remote port. If the remote port cannot provide the proper signal to indicate its capability, the 10/100 Mbps port on the switch defaults to half-duplex mode. 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.

One toggle switch is assigned to each 10/100 Mbps port and can be set to full-duplex (FDX) mode or auto-duplex (AUTO) mode.
