Dahua - DH-PFS4218-16ET2GF-240 - 16-Port PoE Desktop Managed Fast Ethernet Switch ( IEEE802.3bt 90W PoE)
Part number:
DH-PFS4218-16ET2GF-240
Price:

The 16-port managed desktop switch is designed for field transmission applications and for high-definition video. The switch is equipped with a high-performance switching engine, a large buffer, low transmission delay, and high reliability. In addition to the 16 PoE ports, the switch offers two (2) gigabit uplink combo ports with a PoE budget of 240 W. The switch also delivers powerful network management functions including CLI, iLinksView, and Web and network management software based on SNMP.

 

The switch supports IEEE 802.3bt technology that delivers 90 W via a PoE port and drives high-power infrastructure for smart building systems, safe cities, thin clients, and many more applications. With this standard, the switch can power IT and IoT devices that demand increased power consumption resulting in lower installation and wiring costs.
