【Introduction】 19 PORTS GIGABIT UPLINK 100M ETHERNET POWER SWITCH (POE SWITCH), USING HIGH-QUALITY HIGH-SPEED NETWORK IC AND THE MOST STABLE POE CHIP, POE PORT SUPPORT 802.3AF AND 802.3AT STANDARD BOTH, THIS SERIES OF POE SWITCH CAN BE 10/100M ETHERNET THE NETWORK PROVIDES A SEAMLESS CONNECTION, AND THE POE POWER PORT CAN AUTOMATICALLY DETECT AND POWER THE POWERED DEVICES THAT COMPLY WITH THE IEEE802.3AF OR IEEE802.3AT STANDARDS. THE NON-POE DEVICE INTELLIGENTLY DETECTS NO POWER AND ONLY TRANSMITS DATA. POE IS POWER OVER ETHERNET, WHICH REFERS TO THE TRANSMISSION OF DATA SIGNALS TO SOME IP-BASED TERMINALS (SUCH AS IP PHONES, WIRELESS ACCESS APS, NETWORK CAMERAS, ETC.), BUT ALSO PROVIDES DC POWER FOR THIS DEVICE. TECHNOLOGY, THESE DEVICES THAT RECEIVE DC POWER ARE CALLED POWERED DEVICES. 【MAIN FEATURES】 16*10/100M POE ports + 2* 10/100/1000M Ethernet Uplink ports+1* Gigabit SFP Uplink Port； Comply with IEEE 802.3, IEEE 802.3u, IEEE802.3ab ,IEEE802.3z IEEE802.3x standards； Ethernet port supports 10/100M adaptive； Flow control mode: full-duplex adopts IEEE 802.3x standard, half-duplex adopts Back pressure standard； Support port auto flip (Auto MDI/MDIX)； Automatically supplied to adaptive devices； Panel indicator monitoring status and help failure analysis； Support for VLAN mode, OFF mode and Extend mode； Compatible with 1 U rack installation 【Application Environment】 Metro Optical Broadband Network: Data network operators such as telecommunications, cable TV, and network system integration,etc. Broadband private network: Suitable for financial, government, oil, railway, electric power, public security, transportation, education and other industries Multimedia transmission: Integrated transmission of images, voice and data, suitable for remote teaching, conference TV, videophone and other applications Real-time monitoring: Simultaneous transmission of real-time control signals, images and data
