Best Price for Modem Voip - Fast Delivery 120W Internal Power Supply IEEE802.3af/at 4 Port Ethernet Switch POE – HDV

Description:

HDV-4GE POE+2GE UP-ND is a standard PoE powered Ethernet switch designed and developed by HDV optical communication equipment. It adopts the latest high-speed Ethernet switch chip and ultra-high backplane bandwidth design. It has strong data processing capabilities and improves smooth data transmission performance.Supports 4*10/100/1000Mbps Ethernet RJ45 ports with PoE function and 2*10/100/1000Mbps Ethernet uplink RJ45 ports, each port supports auto rollover function (Auto MDI / MDIX).Among them, 4 ports with PoE function, all support IEEE 802.3af / at standard PoE power supply, which can be used as a power supply device for Ethernet. The maximum power supply of a single port is 30W and the maximum power of the whole machine is 120W. It can automatically detect and identify the IEEE 802.3af / at standard Powered equipment.Powered by a network cable, it supports 250 meters of long-distance transmission and supports priority mechanism power supply.

Features:
• Port Performance
Provide 4*10/100/1000Mpbs RJ45 adaptive high-speed forwarding data port;
Provide 2 * 10 /100/1000Mpbs RJ45 uplink port;
Each port supports MDI / MDIX automatic rollover and auto-negotiation, and supports IEEE 802.3x full-duplex flow control and Backpressure half-duplex flow control;
• PoE Power Performance
4 * 10 /100/1000Mpbs RJ45 port supports PoE + power supply, meeting the requirements of PoE power supply in security monitoring, teleconference system, wireless coverage and other scenarios;
