Dahua DH-PFS3409-4GT-96 9-Port Unmanaged Desktop Switch with 4-Port PoE

System Overview

• • DH-PFS3409-4GT-96 is an unmanaged Hardened PoE Switch with 4× 10/100/1000 Mbps PoE Ports. It provides 4 × 10/100/1000 Mbps Ethernet ports , 4 × 1000 Mbps SFPs and 1 ×10/100/1000 Mbps Ethernet uplink ports . The product is equipped with two types of
    transmission modes (Extend Mode On/Extend Mode Off). It also supports PoE watchdog to avoid manually maintenance and device restart, which can realize the intelligent management and reduce the cost.

Functions

Intelligent PoE

• • Provides control over power consumption and offers real-time monitoring to ensure power supplies receive priority with important ports and to prevent malfunctions caused by changes in power consumption. Supports ultra wide power supplies and is able to adapt to IPC power fluctuations.

BT 90W

• • The red ports support IEEE802.3af, IEEE802.3at, IEEE802.3bt and Hi-PoE standards, with a maximum output power consumption rate of 90W per port. Suitable for powering high-power devices.

PoE Watchdog

• • Adopts the innovative PoE Watchdog. PoE Watchdog can be switched on by dialing or turning on the WEB page switch. It enables the switch to automatically detect port status and restart failed ports to recover connection in case of IPC connection exception. This enables intelligent
    operation and maintenance management in its truest sense, effectively reducing manual maintenance costs.

Long Distance PoE

• • By dialing or enabling long-range transmission on the WEB interface, the transmission distance of a PoE port can be up to 250 m, meeting the requirements of wired transmission (bandwidth reduced to 10 Mbps).

8-pin Assignment PoE Power Supply

• • Supports 8-pin simultaneous power supply (1/2/4/5 positive, 3/6/7/8 negative). Signal lines and idle lines supply power at the same time. Compatibility with IPC is enhanced. Cable loss is reduced. Loading capacity is increased.

Scene

• • The device is applicable for use in different scenarios, including home, office, server farm, and small mall.
