100Mbps “100” position (factory default) forces the UTP port to operate at 100Mbps. Setting this DIP-switch
to UTP 10Mbps “10” position forces the UTP port to operate at 10Mbps. Adjust the “10/100” DIP-switch to
match the speed of the connecting UTP device.
When the UTP “AN/Man” DIP-switch is in the auto-negotiate “AN” position and the UTP 10/100
DIP-switch is in the “100” position, the UTP port auto-negotiates to 100Mbps or 10Mbps. When in the
“10” position, the UTP port only operates at 10Mbps. Refer to the table above for a detailed explanation.

SW5 - UTP Full/Half Duplex “FDX/HDX”
When the UTP “AN/Man” DIP-switch is in the manual “Man” position, the UTP Full/Half-Duplex
“FDX/HDX” DIP-switch determines the duplex operation mode of the UTP port. Setting the UTP
Full/Half-Duplex DIP-switch to UTP Full-Duplex “FDX” position (factory default) forces the UTP port to
operate in Full-Duplex. Setting this DIP-switch to UTP Half-Duplex “HDX” forces the UTP port to operate
in Half-Duplex. Adjust the UTP Half/Full-Duplex DIP-switch to match the duplex mode of the connecting
UTP device.
When the UTP “AN/Man” DIP-switch is in the auto-negotiate “AN” position, and the UTP Full/Half-Duplex
DIP-switch is in the Full-Duplex “FDX” position, the UTP port auto-negotiates to Full or Half-Duplex. When
in the Half-Duplex “HDX” position, the UTP port functions only in Half-Duplex for the speed selected.
Refer to the table on the previous page for a detailed explanation.
