If a switch uses 1150 W power modules, it is recommended that the switch be installed in an 800 mm or deeper standard cabinet. If the switch is installed in a 600 mm deep cabinet, the rear door of the cabinet cannot be closed.


Table 5-70 describes the functions of a 1150 W AC PoE power module.

Table 5-70 Functions of a 1150 W AC PoE power module



PoE power supply

Provides a maximum of 785.4 W PoE power.

Input protection

Provides protection against input overcurrent and input undervoltage.

Output protection

Provides protection against output overvoltage, output overcurrent, and output short-circuit.

Overtemperature protection

When the temperature of the power module exceeds a specified threshold (70°C), the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.

Hot swapping



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.

Table 5-71 Description of indicators on a 1150 W AC PoE power module panel






  • The AC power input is abnormal, for example, no AC input power, AC input overvoltage, or AC input undervoltage occurs.
  • The AC power output is abnormal, for example, output undervoltage or overtemperature occurs.

Steady on: The AC power input is in the normal range.

Blinking: The AC power output is abnormal, for example, overvoltage, overcurrent, or short circuit occurs.
