2.4.1 Introduction to the Data Plane

NPUs are key parts on the CX600-X2-M8 and are responsible for network processing and data
exchange between PICs and NPU-50s.
The procedure for data processing is as follows:

Description
If the indicator is steady green, it indicates that the fan module works
normally.
The indicator is off when the fan module is unregistered, powered
off, or has a hardware fault.
If the indicator is steady red, it indicates that the fan module fails.
The IP packets sent from PICs and NPU converge at a convergence module.
The NP processes the IP packets.
The TM module performs traffic management on the IP packets.
