Huawei W2PSA2230 2200 W AC Power Module, can be installed in card slot on S7703, S7706, S7712 switch.
Functions and Features
Function
Description
Input protection
Input undervoltage protection
In this protection state, the power module is turned off and stops supplying power. When the system recovers from input undervoltage, the power module can automatically start supplying power again.
Input overcurrent protection
In this protection state, the power module is turned off and stops supplying power. The power module cannot automatically start supplying power again and needs to be replaced.
Output protection
Output overvoltage protection
In this protection state:
If output overvoltage is caused by the power module itself, the power module stops supplying power. When the system recovers from output overvoltage, the power module cannot automatically start supplying power again.
If output overvoltage is caused by increase of the input voltage received from the external power source, the power module stops supplying power. When the system recovers from output overvoltage, the power module can automatically start supplying power again.
Output overcurrent protection
In this protection state, the output current is limited to a certain value. When the system recovers from output overcurrent, the power module can automatically start supplying power again.
Output short-circuit protection
In this protection state, the power module supplies power intermittently, and the output current is limited to a range. When the system recovers from output short-circuit, the power module can automatically start supplying power again.
Overtemperature protection
When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.
Hot swapping
The power module is hot swappable.

W2PSA2230 FAQ
Q1: Is this power module compatible with Huawei S6730-S48X6C switches? Is an additional adapter required?
A1: Fully compatible! No additional adapter is needed. Simply insert it into the switch's power slot. It is compatible with the device's native power supply logic and is plug-and-play.
Q2: How does the "hot-swap" function work? What precautions should be taken when replacing a faulty power supply?
A2: Supports hot-swapping! Press and hold the anti-misinsertion clip to directly remove the faulty module and insert the new module. The replacement process takes less than 1 minute, and the service is unaware of the change. An anti-static wrist strap must be worn during operation.
Q3: What are the core differences between this and Huawei's 2000W power module (such as ES1D2PS00P00)? How to choose?
A3: The core differences lie in power and compatible scenarios: The W2PSA2230 (2200W) has higher power and is suitable for high-load, fully-equipped devices; the 2000W model is suitable for medium-to-low load scenarios. For full-load service slots, select 2200W; for normal loads, select 2000W.
