Description
DH-PFS4226-24ET2GF-360
The
Dahua DH-PFS4226-24ET2GF-360 24-port Managed Desktop Gigabit 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 24 PoE ports, the switch offers two (2) gigabit uplink combo ports with a PoE budget of 360 W. The switch also delivers powerful network management functions including CLI, iLinksView, and Web and network management software based on SNMP. The switch is housed in a sealed, metal case that offers low power consumption.
