POE POE+ POE++

        1.Running power concurrent to data over structured telecommunications cabling
        2.Power can be injected by the Ethernet switch (end-span), or Power can be injected by a device inserted into the telecommunications channel (mid-span)

ADVANTAGES

        1.Simplified infrastructure management
        2.Lowered power consumption
        3.Reduced operational costs for application such as VoIP
        4.Improved safety due to separation from the building’s main AC power ring
