DH-PFS4218-16ET-240 16 Port PoE Smart Management Swtich 240W
DH-PFS4218-16ET-240 is a dedicated PoE switch for security industry, which is different from general switch. PoE management function realizes power control and real-time port consumption display. It’s widely used in surveillance project. DH-PFS4218-16ET-240 also provides 250 meters long distance PoE transmission and ‘orange port’ for Hi-PoE powered device.
Two of the uplink ports support a self-adaptive 10/100/1000 Mbps RJ-45 port or a 1000 Mbps optical port.
The switch features intelligent PoE power consumption management to help keep the power and data flowing, even when the switch experiences a power fault. Intelligent PoE monitors the power consumption of the connected devices, and in the event of large power fluctuations, the switch shuts down one port at a time rather than shutting down all ports. Unlike typical switches that shut down all ports as once, this switch shuts down the highest number port first, then the next highest number until the switch detects the power consumption is below the PoE budget. Green PoE can power on and power off according to time strategy. It can also realize PoE legacy support.
The red port supports the IEEE802.3bt and the Hi-PoE standards. The maximum power consumption is 90W.
The switch employs an innovative PoE watchdog function that automatically detects a network port failure and restarts network communication on the port. This functionality avoids manual maintenance and network restarts, saving time and reducing costs.
