Media Converter and Network Interface Device User Manual

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.
3.2.1.5 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.
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.
SW6 SW7 SW8 Result
Left Left Left Enables Link Segment mode (LS).
Right Left Left Enables Link Propagate mode (LP).
Left Right Left
Enables Remote Fault Detection mode plus
Link Segment mode (RFD+LS).
Right Right Left
Enables Remote Fault Detection mode plus
Link Propagation mode (RFD+LP).
Left Left Right Enables Symmetrical Fault Detect mode (SFD).
Right Left Right Illegal setting. LS mode is enabled.
Left Right Right Illegal setting. LS mode is enabled.
Right Right Right Illegal setting. LS mode is enabled.
SW6 SW7 SW8 Result
Down Down Down Enables Link Segment mode (LS).
Up Down Down Enables Link Propagate mode (LP).
Down Up Down
Enables Remote Fault Detection mode plus
Link Segment mode (RFD+LS).
Up Up Down
Enables Remote Fault Detection mode plus
Link Propagation mode (RFD+LP).
Down Down Up Enables Symmetrical Fault Detect mode (SFD).
Up Down Up Illegal setting. LS mode is enabled.
Down Up Up Illegal setting. LS mode is enabled.
Up Up Up Illegal setting. LS mode is enabled.
NOTE: Connecting two converters set to any of the RFD modes are illegal and will cause a “deadly
embrace” lockup.
NOTE: It is recommended to keep the LS setting (default) until initial configuration is complete.
