Huawei S12700 ET1D2MPUBC00 Main Processing Unit B (Optional Clock)
The ET1D2MPUBC00 can be installed in slots 13 and 14 of an S12710 chassis.
Functions of the ET1D2MPUBC00
The ET1D2MPUBC00 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 ET1D2MPUBC00 consists of the following functional modules:
Control module: functions as the control plane and management plane for the ET1D2MPUBC00 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 ET1D2MPUBC00.
Device management and monitoring module: provides functions of a controller area network (CAN) bus module to monitor the ET1D2MPUBC00 and manage the CAN bus modules of LPUs.
Power supply module: provides power supply for the ET1D2MPUBC00.
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 ET1D2MPUBC00, perform an active/standby switchover.

ET1D2MPUBC00 FAQ
Q1: What are the core advantages of this main control unit? Is it suitable for small to medium-sized networks with limited budgets?
A1: The core advantages are dual redundancy for high reliability, cost-effectiveness, basic scalability, and intelligent operation and maintenance; the cost is moderate, eliminating the need to pay excessive fees for redundancy, making it ideal for small to medium-sized networks with limited budgets.
Q2: Which S9700 models does it support? Can it directly replace the old main control unit of a single-controller switch?
A2: It is compatible with the entire Huawei S9703/S9706/S9712 series; it can directly hot-swap the old single-controller unit without downtime, and automatically adapts to existing service boards after replacement, quickly achieving dual redundancy upgrades.
Q3: Does dual redundancy deployment require additional software configuration or a license?
A3: No additional configuration is required. Redundancy is automatically enabled after inserting the second main control unit, and it is compatible with the existing S9700 series switch system. No additional license purchase is required.
Q4: How does its energy consumption and scalability compare to other dual-redundant main control units of the same level? A4: Single main controller power consumption ≤65W, saving 25% more energy than similar products; supports expansion of 8 service boards, meeting more than 90% of the expansion needs of small and medium-sized networks, balancing scalability and practicality.
