The ET1D2SFUA000 provides the data plane for the entire system. The data plane provides high-speed and non-blocking data channels for service switching between service modules.
The ET1D2SFUA000 consists of the following functional modules:
Switching module: functions as the data plane and provides high-speed service channels for service switching.
Local clock module: provides the working clock for the chips of the switching module, management module, and monitoring module on the ET1D2SFUA000.
Power supply module: provides power supply for the ET1D2SFUA000.
Function
Description
Basic functions
The ET1D2SFUA000 is core of data switching on the S12704, S12708 and S12712.

Load balance
If a device is equipped with multiple SFUs, these SFUs forward traffic simultaneously. When one SFU becomes faulty, traffic on the SFU is automatically switched to other SFUs. However, if all the other SFUs are fully loaded, services on the faulty SFU will be interrupted.
Hot swapping
Supported
NOTICE:
Before removing a running SFU, hold down the OFL button on the SFU until the OFL indicator turns red.

ET1D2MPUA000 FAQ
Q1: What are the core advantages of this main control unit? Is it suitable for low-budget basic scenarios?
A1: The core advantages are stable basic control, high cost-effectiveness, easy deployment, and low power consumption; the cost is only half that of a dual-redundant main control unit, and its functions match basic control requirements, making it very suitable for small and medium-sized networks with low budgets.
Q2: Which S9700 models does it support? Can it directly replace the old basic main control unit?
A2: It is compatible with Huawei S9703/S9706 basic switches; it can directly hot-swap replace the old basic main control unit of the same series without downtime, and automatically adapts to existing service boards after replacement, without affecting service operation.
Q3: Is stability guaranteed compared to a dual-redundant main control unit?
A3: Optimized stable control logic for basic scenarios, with a low failure rate, meeting over 90% of the stable operation requirements of small and medium-sized networks; for higher reliability, link redundancy design can be used.
Q4: Is installation and configuration complex? Is professional personnel required?
A4: Simple installation, supports hot-swapping; equipped with a simple wizard and fault prompts, combined with Huawei's basic management tools, even non-professionals can quickly complete the deployment, and the operation and maintenance threshold is low.
