Why Using Power Over Ethernet With the introduction of Ethernet-enabled devices expanding geometrically, the need to power these devices from standard AC power outlets has become a limiting factor. IP telephones, wireless access points, IP cameras and device servers are examples of devices limited by the need to have an AC power outlet nearby to plug in a DC power adapter. In term of practical issues , power supply installation and wiring adds labor and results in the mess of extra wiring; worst case, the lack of nearby AC power means devices cannot be installed where they are needed.

With the introduction of Ethernet-enabled devices expanding geometrically, the need to power these devices from standard AC power outlets has become a limiting factor. IP telephones, wireless access points, IP cameras and device servers are examples of devices limited by the need to have an AC power outlet nearby to plug in a DC power adapter.

In term of practical issues , power supply installation and wiring adds labor and results in the mess of extra wiring; worst case, the lack of nearby AC power means devices cannot be installed where they are needed.

IEEE 802.3af Standard In response to this need, IEEE developed IEEE802.3af to standardize a system of supplying low voltage power to networked devices via the communications line. Released in mid-2003 , Power over Ethernet (POE). PoE supplies power to network devices over the same standard Category 5e (CAT-5) cabling that carries the data. Devices can be installed wherever structured Ethernet wiring is located, without the need for AC power outlets nearby. The 802.3af specification involves delivering nominal 48 volts ( 36 to 57 VDC in standard ) of DC power over unshielded twisted-pair wiring. The total amount of continuous power that can be delivered to each node is 12.95 watts. (max. load power 15.4W, after counting cable power lost left 12.95W) 802.3af power sourcing equipment contains a detection mechanism to prevent sending power to noncompliant devices.

Power over Ethernet (POE).

PoE supplies power to network devices over the same standard Category 5e (CAT-5) cabling that carries the data. Devices can be installed wherever structured Ethernet wiring is located, without the need for AC power outlets nearby.

The 802.3af specification involves delivering nominal 48 volts ( 36 to 57 VDC in standard ) of DC power over unshielded twisted-pair wiring.

The total amount of continuous power that can be delivered to each node is 12.95 watts. (max. load power 15.4W, after counting cable power lost left 12.95W)

802.3af power sourcing equipment contains a detection mechanism to prevent sending power to noncompliant devices.

PSE and PD(1) In the PoE scheme, two different types of devices are involved: Power Sourcing Equipment (PSE) and Powered Devices (PD). PSEs provide the DC power to PD s. PSEs source up to 12 watts at 48 volts to each PD. A PSE may be an endspan device or a midspan device An endspan device typically is a network switch enabled to provide PoE power on each port. A midspan device is connected in-line to each end device and adds power to the line. A simple device called Injector is explained in coming slide. PD s are PoE-enabled network end devices equipped to accept low voltage power transmitted over structured Ethernet CAT-5 cabling. For non-POE device, a device called Spilitter can be used with POE line

An endspan device typically is a network switch enabled to provide PoE power on each port.

PSE – Power Sourcing Equipment’s main functions are: To search the link section for a PD. Optionally classify the PD. Supply power to the link section. (only if a PD is detected) Monitor the power on the link section. PSE and PD(2) PD – Powered Device : The Power Class of PD : Once a PD is discovered, a PSE may optionally perform PD classification by applying a DC voltage and current to the port, al located power is subtracted from total power budget. Any unclassified PD is considered to be a class 0 device. Class 3 is similar to Class 0 in that it also requests full power, but a Class 3 PD will always draw at least 7W according to the standard, whereas a Class 0 device could draw anything up to full power PD Device like: PoE IP-Cam (5~12W), PoE IP-Phone (3~6W), PoE Wi-Fi access point (4~11W), PoE RFID Reader, PoE door controller, PoE printer server….etc The Power Class of PD Class Usage Maximum Power Levels at Input of Powered Device 0 Default 0.44 to 12.94 1 Optional 0.44 to 3.84 2 Optional 3.84 to 6.49 3 Optional 6.49 to 12.95 4 Reserved Reserved for Future Use

What is PoE Repeater ( or Extender ) Cables in the Ethernet network are limited to 100m in length. Frequently network equipment must be connected over greater distance. POER-201 is the one for the solution. How it works? PoE Repeater POER-201 forwards LAN power via network cable by Power Over Ethernet technology and requires no local power supply to be installed for the purpose. It can also forward Ethernet packets onto connected device such as IP camera, wireless AP or IP phone which embedded with PoE-PD (client PoE). Extending PoE Distance > 100m PoER-201

Daisy-Chaining to longer Distance It’s possible to connect two or more PoER in a chain, with up to 100 meters of cable between each PoER or device. Each extension will have transmission lost + extender power dissipation. The total is less than 3 watts. If you like to link two POER-201 to extend to 300m, the PD power consumption is limited to (15.4 -3 -3 = 7.4 watts )

IEEE802.3at (PoE+) The enhancement of the PoE+ is to increase the amount of power that can be supplied from PSE to the PDs, via the Cat-5, Cat-5e, Cat-6 unshielded twisted pair wiring. The new specification attempts to bring the power supplied up to at least 24 watts . (draft 3.0 proposed; 30W in draft 2.0) With new standard applied, there will have more PD available for PoE applications, eg: Security IP Camera with pan/tilt/zoom capabilities, door controllers, POS terminals, videophones and dual-band wireless access points….etc.
