DC input voltage is provided through J1 and J3. This board supports a dual power source in sharing mode and redundant mode. If the power supplies are in redundant mode, make sure the main power supply is connected to J1 and a backup power supply is connected to the J3 connector.
The minimum PSE port voltage is 44 VDC for Type 1, 50 V for Type 2 and Type 3, and 52 V for Type 4. The maximum DC voltage at VPWR is 57 V for all types. During evaluation, choose the appropriate DC power supply for the different type environment.
