Omnitron Systems Technology FlexSwitch 6540 FK - Manual (Page 7)

Note: Attaching the Auto-Negotiating UTP port of the 6540-FK to a device
with a manual/forced /hard-coded UTP port may result in an unpredictable
port setting with excessive collisions and poor link performance. When
operating in Manual mode, both mating ports MUST be set manually to the
same speed and duplex mode.
3.3.2 Media Converter Modules - On-Board
The Media Converter Modules have on-board DIP-Switches for the
configuration of the Link Modes and Backplane connectivity. See Section 6.0
for more information on the Link Modes. The modules are pre-configured as
illustrated below.

Media Converter Module On-Board DIP-Switches
Remote Fault Detection “RFD” DIP-Switch
When the Remote Fault Detect “RFD” DIP-Switch is in the UP position, the
RFD mode is selected. When in the DOWN position (factory default), the
RFD mode is disabled.
Note: Connecting two converters with both set to RFD mode is an illegal
setting and will cause a “deadly embrace” lockup.
A and B Backplane Enable “BPOEN” DIP-Switch
This DIP-Switch must be in the UP position (factory default) for the module to
operate correctly. The backplane must be enabled for the Media Converter
Modules to communicate.
Link Propagate/Link Segment “LP” DIP-Switch
When both the Link Propagate/Link Segment “LP” and the Remote Fault Detect
“RFD” DIP-Switches are in the DOWN position (factory default), Link Segment
mode is enabled. When the Link Propagate/Link Segment “LP” DIP-Switch is
in the UP position, and the Remote Fault Detect “RFD” DIP-Switch is in the
DOWN position, Link Propagate mode is enabled.
Note: Setting both the “LP” and the “ RFD” to the UP positions on the same
module is an illegal mode that will result in unpredictable behavior.
