Huawei CE128000 Series Switch PDC-2200WC DC Power Module. Functions of the PDC-2200WC
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 overvoltage, 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
In this protection state, the power module is turned off and stops supplying power. When the system recovers from output overvoltage, the power module cannot automatically resume power supply.
The OUTPUT indicator shown in Figure 2 is off.
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.
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.
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.
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.

PDC-2200WC FAQ
Q1: Which Huawei devices does the PDC-2200WC support? How compatible is it?
A1: It mainly adapts to Huawei CE8800, CE7800, and CE6800 series mid-to-high-end switches. Its size and power supply interface are perfectly matched, with 100% compatibility. It can be directly plugged in and used.
Q2: What are the advantages of -48V high-voltage DC input? Can it be connected to ordinary AC power?
A2: High-voltage DC power supply has lower energy consumption and higher security, adapting to professional data center architectures. This module only supports -48V DC input and cannot be directly connected to ordinary AC power. It needs to be used with a high-voltage DC power supply system in the data center.
Q3: How is redundancy deployment achieved? Will a single module failure affect equipment operation?
A3: It supports 1+1, 2+1, and other redundancy modes, with automatic collaborative work between modules. After a single module fails, the remaining modules instantly take over power supply, ensuring seamless equipment operation and uninterrupted service. The faulty module can be replaced later.
