Huawei NE40E-X2

1.1 Overview
The NE40E-X1 is a high-end network device developed by Huawei. This device is based on the
VRP and applies to the access, convergence, and transmission of Metro services.
The NE40E-X1 has great capabilities for network access, Layer 2 switching, and EoMPLS
transmission, and supports a wide range of high-speed and low-speed interfaces. In addition, the
NE40E-X1 supports triple-play of voice, video, and data services and can bear 2G, 3G, and LTE
services simultaneously. The NE40E-X1 can be deployed together with Huawei NE, CX, and
ME series products to build a hierarchical Metro Ethernet network that offers extensive services.
1.1.1 System Hardware Description
By adopting a centralized routing engine and NP forwarding structure, the NE40E-X1 has a
great capacity and can provide diverse services.
The NE40E-X1 has an integrated chassis that can be installed independently. The main parts of
the NE40E-X1 such as MPUs, NPUs, PICs, fan modules, and PSUs are hot-swappable.
Figure 1-1 shows the outline of the NE40E-X1. The NE40E-X1 provides one slot for the NPU
and four slots for PICs. The network process unit on the NE40E-X1 is NPUI-20. All the PICs
switch data with each other through the NPUI-20. The NPUI-20 has a bidirectional data
processing capability of up to 20 Gbit/s.
The maximum interface capacity of the NE40E-X1 is 52 Gbit/s.

1.1.2 System Architecture
The logical architecture of the NE40E consists of the following planes: data plane, control and
management plane, and monitoring plane, as shown in Figure 1-2. The data plane processes and
switches data packets quickly and smoothly; the control and management plane, as the core of
the system, controls and manages the system; the monitoring plane monitors the ambient
operating conditions.
