Dahua DH-PFS4218-16GT2GF-240 16-Port Gigabit Managed PoE Switch

System Overview

• • DH-PFS4218-16GT2GF-240 is a type of layer-two managed PoE switch. Itprovides 16 gigabit PoE ports and 2 gigabit uplink combo ports. The full load is 240W. With high switching performance and reliability, the product features large cache and low transmission delay, which supports access of Ultra HD video. With all metal design, the device 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.

Functions

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.

Scene

• • Applicable to small and micro-scale monitoring networks such as office desktops, schools, hotels, supermarkets and hospitals.
