Omnitron Systems Technology iConverter 2GXM - Manual (Page 7)

NOTE: The fiber optic ports work in Full-Duplex mode in both Auto and Manual negotiation modes.
3.2.1.2 SW3, SW4, SW5 - Reserved
These DIP-switches are for factory use only and must always remain in the Left/Down position (factory
default).
3.2.1.3 SW6, SW7, SW8 - Link Modes
These three DIP-switches configure the link mode settings. The following table details possible Link Mode
DIP-switch configurations.
PI SA
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

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.

3.2.2.1 SW1 - Backplane Port A Enabled “A-DS/A-EN”
When the DIP-switch is in the Left “A-DS” position (factory default), Backplane Port A of the 2GXM is
isolated from the chassis Backplane. When the DIP-switch is in the Right “A-EN” position, Backplane
Port A of the 2GXM is enabled. This port allows Ethernet Backplane connectivity to an adjacent module
via the chassis Backplane Port A. See the backplane illustrations in Section 2.1.3.
3.2.2.2 SW2 - Backplane Port B Enabled “B-DS/B-EN”
When the DIP-switch is in the Left “B-DS” position (factory default), Backplane Port B is isolated from the
chassis Backplane. When the DIP-switch is in the Right “B-EN” position, Backplane Port B is enabled.
This port allows Ethernet Backplane connectivity to an adjacent module via the chassis Backplane Port B.
See the backplane illustrations in Section 2.1.3.
