Table 2 describes the functions of a 240 W AC power module.

**Table 2** Functions of a 240 W AC power module
Function	Description
System power supply and PoE power supply	The power module supports a maximum of 20 W system power and 220 W PoE power.
Input protection	The power module provides protection against input overvoltage, input undervoltage, and input overcurrent.
Output protection	The power module provides protection against output overvoltage, overcurrent, and short-circuit.
Overtemperature protection	When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.

No.	Name	Description
1	3-pin AC/DC input power socket	Connects the power module to an external power supply system using a power cable with a 3-pin plug. NOTE: The customer needs to prepare the power cable. The recommended conductor diameter of the power cable is 1.0 mm².
2	Four 2-pin DC output power sockets	Connects the power module to a switch using a power cable with a 2-pin plug. NOTE: The customer needs to prepare the power cable. The recommended conductor diameter of the power cable is 1.0 mm².
3	Output indicator (DC 56 V)	Steady on: The power output is normal. Blinking green: The power module is in the output overvoltage or overcurrent protection state. Off: The power output is abnormal or the power module is faulty.
