What is PoE

  Power over Ethernet is a mechanism for supplying power to network devices over the same cabling used to carry network traffic. PoE allows devices that require power (PD) and supply the power (PSE) over existing infrastructure without needing to upgrade it. This feature can simplify network installation and maintenance by using the switch as a central power source for other network devices.

What is PoE - 802.3af Standard in Brief

      802.3af, also known as Power over Ethernet, defines a way to build Ethernet power-sourcing equipment and powered terminals. The specification involves delivering unshielded twisted-pair wiring. 48 volts of DC power over It works with existing cable plant, including Category 3, 5, 5e or 6. The technology supports a point-to-multipoint power distribution architecture, parallel to the data network.

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 lost left 12.95W) 802.3af power sourcing equipment contains a detection mechanism to prevent sending power to noncompliant devices.

What is PoE – What is PSE

     PSE – Power Sourcing Equipment The PSE is the equipment that provides power to PDs. The PSE’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.

802.3af defines two types of power source equipment: Endpoint and Mid span.

Endpoint refers to an Ethernet switch with embedded Power over Ethernet technology. Midspan devices are usually placed between legacy switches and the powered devices.

With PoE injector built in, ED’s PoE switch products are perfect solution for Endpoint applications. 5

What is PoE – What is PD

  

PD – Powered Device

A PD is a device that is either drawing power or requesting power from PSE.

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, allocated 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 0 1 2 3 4

PoE Technology In The Future 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) New standard may have approve by year 2009 with the enhancement mentioned above.

With new standard apply 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.
