What’s the Power Supply Configuration of Huawei S6700 Switch

On a S6700-EI switch, one or two power modules can be configured.

When two power modules are used, they work in 1+1 backup mode to provide power for the device. In the versions earlier than V200R005C00, the AC and DC power modules cannot be configured on the same device, while in V200R005C00 and later versions, they can be configured on the same device.

Figure 1

shows the power supply connections of dual DC power modules. After DC power is transmitted to the PWR module, the PWR module provides -53 V output voltage, and the motherboard provides power for the entire device.

Figure 2 shows the power supply connections of dual AC power modules. After AC power is transmitted to the PWR module, the PWR module provides -53 V output voltage, and the motherboard provides power for the entire device.

What’s the advantages of Huawei S6700 Series Switch Regarding Access Performance

Large-capacity, High-density 10 Gbit/s Access To provide sufficient bandwidth for users, many servers use 10G network adapters, especially servers in data centers. The Huawei S6700 Series Switch can be used in data centers to provide high forwarding performance and 10GE ports. The S6700 (Huawei S6720-32C-SI-AC) has the highest density of 10GE ports and largest switching capacity among counterpart switches. Each S6700 (Huawei S6720S-26Q-EI-24S-AC) provides a maximum of 48 line-speed 10GE ports. Ports of the S6700 support 1GE access and 10GE access and can identify optical module types, minimizing the return on investment and allowing users to deploy service flexibly. Huawei S6700 Series Switch has a large buffering capacity and uses advanced buffer scheduling mechanism to ensure non-block transmission of high traffic volume in data centers.

Hardware Information of Huawei S6700 Switch

For the version mappings, appearance and structure, port description, indicator description, power supply configuration, heat dissipation, and specifications of Huawei S6700 Switch, see the S6700 Hardware Description - Chassis. The below picture shows the logical structure of hardware modules of the switch.

Hardware modules of the Huawei S6700 Switch refer to the SCU (Switch Control Unit), power supply, and fan.

SCU The SCU is fixed on the Huawei S6700 Switch . 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.

Main Control Module

The main control module implements the following functions: Processing protocols 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.

Switching Module

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.

Interface Module

The interface module provides Ethernet interfaces for accessing Ethernet services.

Cards The Huawei S6700 Switch supports service cards. Service cards allow flexible networking and provide cost-effective and customized solutions. NOTE Among S6700 series switches, only S6720-EI/S6720S-EI supports service cards. Huawei S6720-30C-EI-24S-AC
