Referring to Table 2.5 , the IP/GbE interface ports are configurable as redundant
backup connections for systems that require isolated input and output data
networks. There are two possible configurations that map the ports as input or
outputs. The MX8400 data paths configurations for such system are described in
Table 2.5 . These are set via nCompass Control.

Table 2.5 Input Mode Configurations
Input Mode Description Port 1 Port 2 Port 3 Port 4
1 Bidirectional The output mode setting is
ignored. Redundancy switching is
done between the bidirectional
ports.
Bidirectional Bidirectional Not Used Not Used
2 Independent Either one or both input ports can
be configured as an input. No
switching is done between the
inputs ports. If two inputs ports
are employed then they are
totally independent of each other.
Input Input Output Output
3 Autonomous Both inputs are used but only one
at a time. Redundancy switching
is done between the two input
ports. Input Input Output Output
