Function
Table 6-2 describes the functions of a 1000 W AC PoE power module.
Table 6-2 Functions of a 1000 W AC PoE power module
Function Description
PoE power supply Provides PoE power.
Input protection Provides protection against input overvoltage, input
undervoltage, and input overcurrent.
Output protection Provides protection against output overvoltage,
output overcurrent, and output short circuit.
Overtemperature
protection
When the temperature of the power module exceeds
a specied threshold, the power module stops
supplying power. When the temperature falls into
the normal range, the power module automatically
resumes power supply.
Hot swapping Supported
When a power module enters overtemperature protection state, take measures to lower the
ambient temperature. The power module can automatically start supplying power again
when the temperature falls within the normal range.
