NC2244GPE is 28-port PoE unmanaged switch series that supports up to 24*10/100M PoE ports, 2*10/100/1000M ports and 2*1000M SFP ports.
24*10/100M ports support PoE+, conforming to IEEE 802.3af/at standard, single port PoE power up to 30W.
It provides three modes, Extend, Default and VLAN, to adapt to various complex environments.
At the same time, support PoE Auto-check function, which is specially designed to solve the problems of equipment frozen.
It can automatically detect the frozen PD equipment and restart the ports’ output of PSE, and restart the PD device. It greatly reduces the maintenance difficulty of engineering.
It supports the PoE usage rate indication, which is convenient to show the consumption of PoE power.
It has a high anti-interference ability, the product supports 6KV surge protection, and 6KV contact / 8KV air ESD protection.
It supports wall hanging and desktop installation, reliable and durable, and can be used in security network video monitoring, network engineering and other occasions.
This switch series contain 450W and 300W power module, two versions to choose.
