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.

LE0MPSA08 FAQ
Q1: Which Huawei switches is this power module compatible with? Does it support hot-swapping?
A1: It is exclusively compatible with the entire Huawei S9300 series (S9303/S9306/S9310/S9312, etc.); it supports hot-swapping and can be replaced online without interrupting device operation.
Q2: What scenarios is the 800W power supply suitable for? What are its advantages compared to higher power supplies?
A2: It is suitable for S9300 light to medium load scenarios (2-6 service boards), edge data centers, branch offices, etc.; its advantages are precise power matching, lower cost, and adaptability to environments with limited power supply, resulting in higher cost-effectiveness.
Q3: What is the input voltage range? Does it support redundant power supply?
A3: The input voltage is compatible with AC 100-240V/DC -48V, adapting to different data center power supplies; it supports N+1 redundancy mode to improve power supply reliability.
Q4: How do I determine if I need to select this 800W power module? Is the installation complicated?
A4: When the S9300 is equipped with 2-6 service boards, the power supply in the data center is limited, or an old 800W power supply needs to be replaced, it is recommended to choose this option; no professional tools are required for installation, just insert it directly into the S9300 power supply slot.
