Advantages Of PoE+Switches

- Sep 27, 2019-

(1) Higher power: PoE + switches can provide up to 30W power per port, while PoE switches can provide up to 15.4W power per port. The minimum power available on the power supply equipment of the PoE switch is 12.95W per port, while the minimum power available on the PoE + switch is 25.5W per port.

(2) Compatibility is stronger: PoE and POE + switches distribute power levels from 0-4 according to how much power they need. When a power supply device is connected to a power supply device, it supplies its category to the power supply device so that the power supply device can provide the correct power for it. The first layer, second layer and third layer devices need very low power, low power and medium power respectively, while the four-layer (PoE+) switches need a lot of power and can only be compatible with PoE + power supply devices.

(3) Further cost reduction: It is simpler for PoE + to work with ordinary Ethernet interfaces using standard cabling (Cat 5), so there is no need for "new lines". This means that existing network wiring infrastructure can be utilized without the need to run high-voltage AC power or separate power connections for each embedded switch.

(4) More powerful: PoE + uses only CAT5 (which has eight internal wires, compared with four CAT3 wires), which reduces the possibility of impedance and power consumption. In addition, PoE + allows network administrators to provide greater functions, such as providing new remote power diagnostics, status reporting and power management for power supply devices (including remote power cycle for embedded switches).

The above is the difference between PoE switch and PoE + through the introduction above, you should understand the difference between the two. In short, PoE switches and PoE + switches can supply power for network switches such as network cameras, AP and IP telephones, and have high flexibility, stability and anti-EMI capability.
