NC3244PGM(4GS)-450 is a 28-port full gigabit managed PoE switch series that supports up to 24*10/100/1000M PoE ports and 4*1000M SFP ports. 24*10/100/1000M ports support PoE+, conforming to IEEE 802.3af/at standard, single port PoE power up to 30W.
Power failure: if the PD device is disconnected from the network, the POE switch will quickly (usually within 300~400ms) stop the power supply for the PD device, and repeat the test process to check whether the cable terminal is connected to the PD device.A complete POE system includes two parts: PSE, Power Sourcing Equipment and PD, Power Device. POE switch is one of PSE devices.It supports L2 management, such as QoS, VLAN, MSTP, Multi-brocast, ports management and PoE management.
It has a high anti-interference ability, the product supports 6KV surge protection, and 6KV contact / 8KV air ESD protection.
PSE device is the device that powers the Ethernet client device and is the administrator of the entire POE Ethernet power supply process.It supports wall hanging and desktop installation, reliable and durable, and can be used in security network video monitoring, network engineering and other occasions.The PD device is the client of the POE system that receives the PSE load powered.
