DAHUA 24 PORT 24FE POE+2G SWITCH
The DH-PFS4226-24ET-240 is a fantastic layer-two managed PoE switch with 24 100 Mbps PoE ports and 2 gigabit uplink combo ports, providing a full load of 240W. Its all-metal design ensures excellent heat dissipation and low power consumption, making it perfect for operating in environments from –10°C to +55°C.
Not only that, but this product also boasts powerful network management functions supported by a CLI, iLinksView, web, and SNMP-based network management software. Experience the ultimate in network management with this amazing PoE switch!
Uplink Combo Port
Two of the uplink ports support a self-adaptive 10/100/1000 Mbps RJ45 port or a 1000 Mbps optical port
Intelligent PoE
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.
BT 90W
The red port supports the IEEE802.3bt and the Hi-PoE standards. The
maximum power consumption is 90W.
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.
Long Distance PoE
Long-distance PoE transmission extends the maximum transmission
distance to 250 m (from 100 m), but reduces transmission speed to a
maximum of 10 Mbps (from 1000 Mbps).
Various Operating Environments
The switch is designed to operate in severe environments and in
temperatures ranging from –10°C to +55°C (14°F to 131°F). The switch
includes a professional-grade surge protection circuit that offers 4
kV (common mode) and 2 kV (differential mode) all-port lightning
protection. This protection reduces damage to the network from a
lightning storm. The switch meets the Class B EMC standard and is
suitable for residential, commercial, and light-industrial applications.
