If something is incorrect t I apologize. Please reach out if you have any questions of concerns and I will do my best to clarify. Thanks for checking us out! The Intellinet Network Solutions 5-Port Gigabit Ethernet PoE+ Switch passes both data and electrical power to a number of PoE-compatible devices via standard Cat5e or Cat6 network cables. Equipped with five Gigabit Ethernet ports – four of which are high-power PoE+ PSE ports – this switch can power wireless LAN access points and bridges, VoIP phones, IP video cameras and more while delivering network speeds of up to 1000 Mbps. Power over Ethernet 802.3at The Intellinet Network Solutions 5-Port Gigabit Ethernet PoE+ Switch supports the IEEE 802.3at protocol and can inject up to 30 watts of power per port. IEEE802.3af- or IEEE802.3at-compliant devices attached to the switch require no additional power, which eliminates the time and expense of electrical rewiring and minimizes the unsightly clutter caused by power supplies and adapters in awkward places such as ceilings and walls. Any mix of PoE and non-PoE devices is supported, and thanks to its short circuit, overload and high-voltage protection function, your equipment is well-protected. Green Ethernet Technology More often than not, a network switch does not utilize all of its ports at all times. Normally, when a computer, notebook, network printer or other network device powers down, the switch continues to consume the same amount of power as if it were active. To overcome this waste of energy, the Intellinet Network Solutions 5-Port Gigabit PoE+ Switch employs the new energy-efficient IEEE 802.3az technology, which detects link status to all connected devices and reduces the power usage of ports that are not in use. To facilitate maximum network performance, the Intellinet Network Solutions switch adjusts power output based on the length of the network cable that is connected to a particular port. Total PoE budget for this switch is 60 watts. Per-port average power distribution is 15 watts; maximum per-port power usage cannot exceed 30 watts. 5-Port (4 x PSD Ports, 1 x 10/100 RJ45 Port) Gigabit PoE+ Switch, 60 Watt Power Budget, Desktop.
