2.6 Logical Structure

This topic describes the logical structure of the CX320.
The BMC module is a management module that provides power control, system monitoring,
and component upgrade functions. The CPU system module is the controlling core that
processes network protocol packets and enables configurations. The converged switching
module is the data processing core that forwards data between internal data processing
modules and external network devices. PIC cards are hot-swappable and used to expand the
port types and quantity.
