The backplane contains the port processor connectors, bus circuitry, and power
connections. The IEN 3000 chassis backplane is passive. That is, no one port processor
need be installed in a specific slot.
The IEN 3000 chassis backplane also contains configurations switches used to configure
multiple chassis as a single IEN node. Refer to Chapter 5, IEN 3000 Configuration for
more information about the IEN 3000 chassis backplane configuration switches.
