Dahua DH-PFS4212-8GT-96 8 Port POE Switch

System Overview

• The device is a layer-2 commercial switch. It provides high-performance switching engine and large buffer memory to ensure smooth video stream transmission. With a full-metal and fanless design, the device features great heat dissipation capability on the shell surface, and
• is able to work in the environment from –10 °C to +55 °C. It adopts EMC (Electro Magnetic Compatibility) protection design, which meets the Class B standard. With Telnet, WEB management, SNMP (Simple Network Management Protocol) and other functions, the device can be remotely managed. The device 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-10 °C to +55 °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.

Intelligent PoE

• Provides control over power consumption and offers real-time monitor- ing 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.

Fast Loop Convergence

• Supports ERPS protocol to provide loop protection. Convergence time can be no more than 50 ms when a link disconnection occurs.

Scene

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