Hardware modules of the S6700 refer to the SCU (Switch Control Unit), power supply, and
The SCU is fixed on the Huawei S6700. Each S6700 has one SCU.
The SCU is responsible for packet switching and device management. It integrates multiple functional modules, namely, the main control module, switching module, and interface module.
The main control module implements the following functions:
Functioning as an agent of the user to manage the system and monitor the system
performance according to instructions of the user, and report the running status of the
device to the user
Monitoring and maintaining the interface module and switching module on the SCU
The switching module, also called the switching fabric, is responsible for packet exchange,
multicast replication, QoS scheduling, and access control on the interface module of the SCU.
The switching module adopts high performance chips to implement line-speed forwarding and fast switching of data with different priorities.
The interface module provides Ethernet interfaces for accessing Ethernet services.
