3.2.1.3 SW3 - UTP Speed Gigabit/10-100 “1000/10-100”
When the “1000/10-100” DIP-switch is in the “1000” position (factory default), the UTP always operates
in 10/100/1000Mbps Auto-Negotiation mode. The UTP port auto-negotiates to a speed of 10Mbps, 100Mbps
or 1000Mbps with the connected UTP device. In this mode, the UTP “AN/Man” and UTP “100/10” DIP-
switches have no effect.
When the “1000/10-100” DIP-switch is in the UP 10/100Mbps “10-100” position and the UTP “AN/Man”
DIP-switch is in the “Manual” position, the UTP port operates at the Speed and Duplex modes set by the
“10/100” and “FDX/HDX” DIP-switches.
When the “1000/10-100” DIP-switch is in the 10/100Mbps “10-100” position and the UTP “AN/Man”
DIP-switch is in the Auto-Negotiation “AN” position, the maximum Auto-Negotiation setting for the Speed,
Duplex and Pause mode of the UTP port is limited by the “10/100”, “FDX/HDX” and Pause “Off/On”
DIP-switches.
See the UTP Port Configuration Matrix.
3.2.1.4 SW4 - UTP 100/10Mbps “100/10”
When the UTP “AN/Man” DIP-switch (described above) is in the manual “Man” position, the “100/10"
DIP-switch determines the speed of operation for the UTP port. Set the “100/10” DIP-switch to match the
speed of the connected UTP device.
See the UTP Port Configuration Matrix.
3.2.1.5 SW5 - UTP Full/Half Duplex “FDX/HDX”
Setting the UTP Full/Half-Duplex DIP-switch to the “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 Full/Half-Duplex DIP-switch to match the duplex mode of the
connected UTP device.
See the UTP Port Configuration Matrix.
3.2.1.6 SW6, SW7, SW8 - Link Modes
These three DIP-switches configure the link mode settings. The following table details possible Link Mode
DIP-switch configurations.

NOTE: Connecting two converters set to any of the RFD modes is illegal and will cause a “deadly
embrace” lockup.
NOTE: It is recommended to keep the LS setting (default) until initial configuration is complete.
