Fdx/Auto Gigabit Toggle Switch - NETGEAR FS509 Installation Manual

As Figure 2-4 shows, a full-duplex (FDX) toggle switch or an auto-duplex (AUTO) toggle switch
are assigned to each 10/100 Mbps port on the Model FS509 switch. The communication mode can
be set to either full-duplex or auto-duplex mode.
Note: In addition to setting the duplex toggle switches to the correct position, make sure
that all Fast Ethernet topology rules are followed.

FDX/Auto Gigabit Toggle Switch

The 1000 Mbps gigabit Ethernet port operates only in full-duplex mode and must only be
connected to other full duplex devices. Setting the switch to Auto enables the port to advertise that
it is running in full-duplex mode; setting the switch to FDX mode does not enable the port to
advertise its mode.
Note: NETGEAR recommends that the FDX/AUTO switch is left in Auto mode, which
is the factory setting.
