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.

W2PSD2201 FAQ
Q1: Which devices is this power module compatible with? Does it support hot-swapping?
A1: Compatible with Huawei S/E series switches, enterprise servers, storage devices, etc., and compatible with standard power supply slots; supports hot-swapping, allowing for online replacement or expansion without interrupting device operation.
Q2: What scenarios is the 2200W power suitable for? What are its advantages compared to ordinary power supplies?
A2: Suitable for high-load scenarios such as enterprise core server rooms and small to medium-sized data centers; its advantages include sufficient power, wide voltage compatibility, support for multi-mode redundancy, and reliability and adaptability far exceeding ordinary power supplies.
Q3: What is the input voltage range? What is the conversion efficiency?
A3: Supports AC 100-240V input voltage, adapting to complex power supply environments; conversion efficiency ≥92%, highly efficient and energy-saving, reducing data center energy costs.
Q4: How do I determine if I need to upgrade this power module? Is installation complicated?
A4: When the device indicates insufficient power supply, insufficient power after adding high-load devices, or when it is necessary to improve power supply reliability, it is recommended to upgrade; no professional tools are required for installation, just insert it directly into the standard power supply slot.
