8What is PoE?Power over Ethernet allows Ethernet networked user devices to be powered over the same 4-pair UTP that provides the network signalPower is 48 volt DC, up to 25.5 Watts at the Powered Device (PD) as per the new 802.3at standardCompatible with all networks, up to Gigabit Ethernet which uses all four pairs for transmissionPOE Definition
9PoE (Power Over Ethernet) 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, called Powered Devices (PDs),such as IP telephones, wireless LAN Access Points, and network cameras to receive power in addition to data, 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.POE Ethernet Switch is commonly called: PSE (Power Sourcing Equipment)POE Terms: PSE, PD
10The Advantages of PoE Some of the advantages of PoE include: • A single cable between switch and Powered Device (PD)• No separate power installation/ connection needed for PD's• Simplified installation and space saving• Device placement is not limited to nearby power sources• PD's can be easily moved to wherever there is LAN cabling• Safety - no mains or primary voltages anywhere• A UPS can guarantee power to devices even during power failure• Devices can be shut down or reset remotely• Little configuration or management requiredAdvantages of using POE with Cameras

14How PoE Works? PoE requires little configuration or management. The PSE automatically determines whether a device connected to a port is a powered device or not, and can determine the power class of the device.The PSE can supply up to 25.5 watts of power (at 48 Volts) to the PD device, while at the same time providing standard Ethernet network connectivity.
15Power Device (PD) Discovery The first step for PSE equipment (an Ethernet switch for example) is to ascertain whether a device plugged into a port is a valid Powered Device (PD). No power is sent down the cable until a signature check is completed.The IEEE 802.3at / af standard for device detection involves applying a DC voltage between the transmit and receive wire pairs, and measuring the received current.A PSE will expect to see approximately 25K Ohm resistance and 150nF capacitance between the pairs for the device to be considered a valid PD.A range around these values is specified in the IEEE 802.3ad standard.The PSE will check for the presence of PD's on connected ports at regular intervals, so power is removed when a PD is no longer connected.POE Discovery Standard
16Power Classification- Discovery Once a PD is discovered, a PSE may optionally perform PD classification by applying a DC voltage and current to the port. If the PD supports an optional power classification it will then apply a load to the line to indicate to the PSE the classification the device requires.Any unclassified PD is considered to be a class 0 device.The IEEE 802.3at standard supports delivery of up to Watts per port (at the PD) that may be used to deliver power to PoE devices.The maximum power consumed by a PD, as specified by the standard, is Watts.The PSE (POE Switch Port) provides the 'extra' power (up to 34.2 watts) to compensate for line loss through the copper (resistance). This factor is calculated on a maximum cable length of 100 Meters
17Power Sent Through The Data Cable An Ethernet cable (CAT5 / 5E / 6) has four twisted pairs (8wires), but only two of these are used for data transfer under the af standard.The spare pairs are used. In this case the unused pairs are used to transfer the power.The data pairs are used. Since Ethernet pairs are transformer coupled at each end, it is possible to apply DC power to the centre tap of the isolation transformer without upsetting the data transfer.The IEEE 802.3af standard did not allow both sets of wires to be used, the new 802.3at standard allows their use.Different vendors PSE equipment may use one or other of the methods to supply power depending upon the PoE engineering design.So the PSE applies power to either the spare wires , data wires or both.The PoweredDevice (PD) must be able to accept power from every option depending upon the class of the device.The voltage supplied is nominally 48V, and a maximum of Watts of power is available at the Powered Device. (PD)An isolated DC-DC converter transforms the 48V to a lower voltage more suitable for the electronics in the Powered Device.

20PoE vs. Power Supplied Locally at Device Reduced cabling costs. Adding power circuits at the point of need can be a significant expense, This way one cable provides both power and data. Cameras and access points & sensors can be moved and wired easily.Reliability associated centralized supplied power. Circuit outage at a desk will take out a VOIP set powered locally. Using uninterruptible power supplies (UPS), Voice over IP (VoIP) telephones can now be deployed without worrying about them not functioning during a power outage.
