Indicator/Button
Description
FAN indicator When the indicator is steady green, it indicates that the fan module
works normally.
When the indicator is off, it indicates that the fan module is

1.4 Data Plane
1.4.1 Introduction to the Data Plane
As key parts of the NE40E-X1, Network Processing Units (NPUs) are responsible for data
processing and data switching between Physical Interface Cards (PICs) and NPUIs.
The procedure for data processing is as follows:
1. The IP packets sent from PICs and 2x10G interfaces on an NPU converge at a convergence
module.
2. The Network Processor (NP) processes the IP packets.
3. The Traffic Management (TM) module performs traffic management on the IP packets.
4. The Fabric Interface Chip (FIC) performs IP packet switching.
