2.12 Ethernet Control 1 & 2
2.12.1 Overview
2.12.1.1 Functional Description
The Ethernet control ports are used to connect the MX8400
Multiplexer to nCompass Control. Depending on the configuration,
both connectors and the floating address have different IP
addresses. However, if required, the floating address can share
the address of one of the connectors. The active control port
switches from ETHERNET 1, when it looses the link (e.g. carrier)
to ETHERNET 2 (only if it has a link). Refer to Chapter 3 for IP
Address information.
Note: The MX8400 can be controlled using a single control connection.
