Dahua DH-PFS4204-2GT-DP 4-Port Gigabit Industrial Swicth with 2-Port Gigabit PoE (Managed)
System Overview
-
- The device is a layer-2 switch. Equipped with high performance switching engine and large buffer memory, it features low transmission delay and high reliability. The solid and sealed all-metal case design and efficient surface heat dissipation make it can work in the environment from –40 °C to +75 °C. The protection for power input end overcurrent, overvoltage and EMC can effectively resist the interference from static electricity, lightning, and pulse. Redundant power supply guarantees stable operation for the system. With Telnet, WEB management, SNMP
and other functions, the device can be remotely managed. It can directly connect to iLinks-View.

Functions
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-diatance 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).
Red Port 90W
-
- The red ports support IEEE802.3af, IEEE802.3at, Hi-PoE and IEEE802.3bt standards, with a maximum output power consumption rate of 90W per port. Suitable for powering high-power devices.
Wide Operating Temperature
-
- Supports working in temperatures between -40 °C to +75 °C. It has built-in professional mine-proof circuits, which effectively reduce the impact of thunderstorms on network systems and improves system robustness, allowing it to readily adapt to harsh environments.
Redundant Power Supply
-
- Redundant power supply ensures that the device is still powered when one power port malfunctions, vastly improving device reliability.
Scene
-
- The device is applicable for use in different scenarios, including corridors and offices.
Fast Loop Convergence
-
- Supports ERPS protocol to provide loop protection. Convergence time can be no more than 50 ms when a link disconnection occurs.
