How Much Power Does a PoE Power Module Provide?

Power over Ethernet (PoE) refers to power supply over a 10Base-T, 100Base-TX, or 1000Base-T Ethernet cable.

PoE provides power for terminals such as IP phones, access points (APs), portable device chargers, point-of-sale (POS) machines, cameras, and data collectors. These terminals are powered when they connect to the network, so the indoor power supply systems are not required. IEEE 802.3af and IEEE 802.3at are PoE standards defined to provide remote power supply for the devices from different vendors. IEEE 802.3af supports a maximum of 15.4 W power and IEEE 802.3at supports a maximum of 30 W power.

Fixed switch(such as S3328TP-EI-24S-AC)
Fixed switches support 250 W (sales part number 02130878), 500 W (sales part number 02130879), 580 W (sales part number 02130953), and 1150 W(sales part number 02130984) PoE power modules. The actual available power of a 250 W PoE power module is around 120 W (measured 123.2 W). The actual available power of a 500 W PoE power module is around 370 W (measured 369.6 W). The actual available power of a 580 W PoE power module is around 380 W (measured 369.6 W). The actual available power of a 1150 W PoE power module is around 800 W (measured 785.4 W).

A 250 W PoE power module can provide 802.3af full power on 8 interfaces or 802.3at full power on 4 interfaces.

A 500 W PoE power module can provide 802.3af full power on 24 interfaces or 802.3at full power on 12 interfaces.

A 580 W PoE power module can provide 802.3af full power on 24 interfaces or 802.3at full power on 12 interfaces.

A 1150 W PoE power module can provide 802.3af full power on 48 interfaces or 802.3at full power on 26 interfaces.

PoE supports remote power supply over a distance of up to 100 m.
