Function
Description
Indicator Status
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 resume power supply.
The Input indicator shown in Figure 2 is blinking green.
Input overvoltage 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 resume power supply.
The Input indicator shown in Figure 2 is blinking green.
Input overcurrent protection
In this protection state, the power module is turned off and stops supplying power. The power module cannot automatically resume power supply.
The Input indicator shown in Figure 2 is off.
Output protection
Output overvoltage protection
If output overvoltage is caused by the power module itself, the power module is turned off and stops supplying power. The power module cannot automatically resume power supply.
If output overvoltage is caused by increase of the input voltage received from the external power source, the power module is turned off and stops supplying power. When the system recovers from output overvoltage, the power module can automatically resume power supply.
If output overvoltage is caused by the power module itself, the Output indicator shown in Figure 2 is off.
If output overvoltage is caused by increase of the input voltage received from the external power source, the Output indicator shown in Figure 2 is steady green.
Output current limiting 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 resume power supply.
The Output indicator shown in Figure 2 is steady green. When the output voltage is lower than 44 V DC, the Output indicator is off.
Output short-circuit protection
In this protection state, the power module supplies power intermittently, and the output current is limited within a range. When the system recovers from output short-circuit, the power module can automatically resume power supply.
The Output indicator shown in Figure 2 is off.
Overtemperature protection
When the temperature of the power module ranges from 55°C to 75°C, the output current reduces linearly as the temperature increases. The Output indicator is steady green.
When the temperature exceeds 75°C, the power module stops supplying power. When the temperature falls below 75°C, the power module can automatically resume power supply. The Output indicator is off.
When the temperature of the power module ranges from 55°C to 75°C, the Output indicator shown in Figure 2 is steady green.
When the temperature exceeds 75°C, the Output indicator shown in Figure 2 is off.
Hot swap
The power module is hot swappable.
-
Heat dissipation
The power module has its own fans, which use a front-to-back airflow design.

PAH-3000WA FAQ
Q1: Which Huawei devices does the PAH-3000WA support? How compatible is it?
A1: It mainly supports Huawei CE9800 and CE8800 series high-end switches. The size and power supply interface are perfectly matched, with 100% compatibility. It can be used simply by plugging and unplugging.
Q2: How is redundancy deployment achieved? Will a single module failure affect device operation?
A2: It supports multiple redundancy modes such as 1+1 and 2+1, with automatic coordination between modules. In the event of a single module failure, the remaining modules instantly take over power supply, ensuring seamless device operation and uninterrupted power supply.
Q3: Is there any energy waste with the 3000W power output? What is the specific performance of the conversion efficiency?
A3: Power is output on demand, with no load redundancy waste; the conversion efficiency is ≥94%, maintaining high energy efficiency within a 20%-100% load range, significantly reducing data center energy costs.
