HUAWEI Power module
The item was tested by our tech, in good working condition
1 Introduction
The PSR1400-A is a built-in power module with AC input and DC output while the PSR1400-D is a built-in power module with DC input and DC output. The PSR1400-D can provide the device with both system power and PoE power, which can be controlled through separate switches.
Table 1 Features of the PSR1400-A and PSR1400-D power modules
Feature | Description |
Protection functions | Support input under-voltage protection, output over-voltage protection, short-circuit protection, over-current protection, and overheat protection |
Hot swap support | Support hot swap with the power switch turned off while the device is in operation |
1+1 hot backup support | Support 1 + 1 hot backup and current sharing |
Caution:
For a device that supports both AC and DC inputs, you can choose either of the two types of power modules as needed, but do not use both types of power modules in the same device.

Figure 2 Schematic view of the PSR1400-D
The PSR1400-D can provide both system power and PoE power outputs. The switch marked “SYSTEM” is used to control the output of the entire power supply system, while the switch marked “PoE” is used to control the output of the PoE power supply. The RJ-45 port (RS485 compliant) on the right of the PoE power switch is the PoE monitoring port.
The PoE power output can be used both for power supply of PoE-powered devices and for auxiliary power supply of devices that do not support PoE. For details, refer to the corresponding installation manuals.
