SW2 - UTP Auto/Manual Negotiation “AN/Man”

When this DIP-switch is in the “AN” position (factory default), the UTP port automatically determines the
Speed, Duplex and Pause mode of the connecting UTP device. If the connecting UTP device cannot
provide the proper signal to indicate its own mode of operation, then the DIP-switch should be set to the
Manual mode “Man” position. Manual mode requires manually configuring the UTP port to match the
Speed and Duplex mode of the connecting UTP device using the “10/100” and “FDX/HDX” DIP-switches.
