3.2.1.3SW3 - 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.

3.2.1.4SW4 - 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.

3.2.1.5SW5 - 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.

3.2.1.6SW6, 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.

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 is illegal and will cause a “deadly embrace” lockup.

NOTE: It is recommended to keep the LS setting (default) until initial configuration is complete.
