Huawei NE40E-X16 Overview

System Overview

The Huawei NE40E series adopt a centralized routing engine and distributed forwarding architecture. This helps to provide rich and flexible service and to perform large-capacity forwarding.

The Huawei NE40E-X16 has an integrated chassis, with main components which all support hot swapping.

The NE40E-X16 supports all the Line Processing Units (LPUs) on the former NE40E, but the Main Processing Units (MPUs) and Switch Fabric Units (SFUs) are new.

The NE40E-X16 has 16 LPU slots. The switching capacity of the entire system is 12.58 Tbit/s.

System Architecture

The NE40E-X16 adopts system architecture. In this architecture, the data plane, management and control plane, and monitoring plane are separated. This design helps to improve system reliability and facilitates upgrading of each plane separately.

System Features

The NE40E-X16 provides the following system features:
  • Unblocked switching network that can be upgraded, with switching capacity at the Tbit/s level
  • Distributed hardware-based forwarding and fast service deployment
  • Compact structure to increase interface density
  • Normalized design of system components
  • Separation of the control channel, service channel, and monitoring channel to ensure non-blacking control channels and monitoring channels
  • Carrier-class high reliability and manageability
  • Shielding at the modular level to meet ElectroMagnetic Compatibility (EMC) requirements
  • Hot-swappable boards, power modules, and fans
  • U-shaped air channels to improve system heat dissipation
  • Distributed power supply to enhance power supply capability for a single chassis
  • Support for 200 mm (7.87 in.) fans
  • MPUs in 1:1 backup mode
  • SFUs in load balancing mode
  • Backup for key components such as power modules, fan modules, clocks, and management buses
  • Protection against incorrect of boards
  • Queries about alarm prompts, alarm indications, running status, and alarm status of the voltage and ambient temperature
