PFS4218-16ET-240 | 16-port 100 Mbps + 2-port Gigabit Managed PoE Switch

DH-PFS4218-16ET-240 is a type of layer-two managed PoE switch. It provides 16 100 Mbps PoE ports and 2 gigabit uplink combo ports. The full load is 240W. 250m PoE Watchdog 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. With all metal design, the product has good heat dissipation and low power consumption, which can work in environments from –10°C to +55°C. The product owns powerful network management functions. Network management system supports CLI, iLinksView, web and network management software based on SNMP.
