Huawei S12700 ET1D2MPUBC01 Main Processing Unit B (Support Secure Boot)
The ET1D2MPUBC01 can be installed in slots 13 and 14 of an S12710 chassis.
Functions of the ET1D2MPUBC01
The ET1D2MPUBC01 integrates the control and switching functions and provides the control plane, management plane, and data plane for the system.
The control plane provides functions such as protocol processing, service processing, route calculation, forwarding control, service scheduling, traffic statistics collection, and system security.
The management plane is responsible for system status monitoring, environment monitoring, log and alarm processing, system software loading, and system upgrades.
The data plane provides high-speed, non-blocking data channels for data switching between service modules.
The ET1D2MPUBC01 consists of the following functional modules:
Control module: functions as the control plane and management plane for the ET1D2MPUBC01 and the entire system, implementing protocol processing, route calculation, forwarding control, system management, and system security.
Switching module: functions as the data plane and provides high-speed service channels for data switching.
Local clock module: provides the working clock for the chips of the control module, switching module, and equipment management and monitoring module on the ET1D2MPUBC01.
Device management and monitoring module: provides functions of a controller area network (CAN) bus module to monitor the ET1D2MPUBC01 and manage the CAN bus modules of LPUs.
Power supply module: provides power supply for the ET1D2MPUBC01.
Function
Description
Basic function
Core of control and management for the S12710 system, and integrates the main control unit, clock unit, switching unit, and system maintenance unit.
Distributed forwarding
Uses a distributed data plane to forward data concurrently.
Memory
4 GB
eUSB card
2 GB
The system configuration data, startup files, system software package, and system logs are saved in the eUSB card by default.
Clustering
Provides 10GE and 40GE optical ports for cluster connection.
Clock
Provides stratum-3 clock, synchronous Ethernet, and IEEE 1588v2 functions when equipped with an LE0D00CKMA00 clock daughter card.
Redundancy backup
Supported
MPU is a mandatory card for switches. Each switch must be configured with one or two MPUs. When one MPU is configured for a switch, the MPU can be installed in either main control slot of the switch. When two MPUs are configured, they work in hot standby mode to improve system reliability. The two MPUs monitor each other. If the active MPU fails, the standby MPU changes to active state to ensure uninterrupted services.
Hot swapping
Supported
Before removing the active ET1D2MPUBC01, perform an active/standby switchover.

ET1D2MPUBC01 FAQ
Q1: What are the core advantages of this main control unit? What guarantees does the dual redundancy design provide?
A1: The core advantages are high reliability, intelligent operation and maintenance, strong scalability, and low power consumption due to dual redundancy. Dual redundancy avoids single points of failure in the main control unit, ensuring seamless fault switching and zero interruption of core network services.
Q2: Which Huawei switch models does it support? Can it directly replace an old main control unit?
A2: It is specifically adapted to the Huawei S9700 series (S9703/S9706/S9712); it can directly replace old main control units of the same series, supports hot-swapping, and the replacement process requires no downtime and does not affect service operation.
Q3: How does its energy consumption and management capabilities compare to other main control units of the same level?
A3: Single main control unit power consumption ≤60W, saving 28% more energy than comparable products; it integrates an intelligent management platform, supports automated configuration and fault diagnosis, offering superior management capabilities and lower operation and maintenance costs.
Q4: In which scenarios with extremely high reliability requirements is it suitable? Is installation complex?
A4: Suitable for core scenarios such as data centers, carriers, finance, and government; supports hot-swapping, installation requires no professional or complicated operations, automatically adapts after being inserted into the switch slot, and is easy to configure.
