  • Detailed introduction
Dv981-pf/pt-poe switch provides the simultaneous transmission of data and power from a network node using class 5 network and more than class 5 network cables. Its port is used for 10/100mbps connection, in which Poe port can also provide ieee802.3af/at standard power supply. Through detection, only 802.3af/at terminal devices are powered after classification, and there is no need to worry about damaging Poe or non Poe devices of private standards. When the AC power supply is unable to supply power or it is inconvenient to obtain power (such as high-end PTZ cameras and WiMAX devices), the dv981 series is designed for wireless networks and security automation applications. With a compact and flexible design, the dv981 series is an ideal choice for small commercial networks that want to use Poe to deploy wireless access points (APS) and IP based network surveillance cameras economically Dv981 series switches greatly reduce the power wiring costs that users, wireless LAN access points, video surveillance cameras and other equipment must spend, and better support new services and applications, thus providing users with higher flexibility and mobility.
Advanced self sensing algorithms only supply power to standard PD terminal devices, so there is no need to worry about damaging private standard Poe or non Poe devices. In addition, when the POE device is not connected, it will stop power supply. Simple and reliable design, dv981 series automatically identifies the needs, speed, duplex and network cable type using auto uplinktm of Poe.
 
Product features:
 
◆ support the power supply of wireless access points (APS) and network surveillance cameras through Ethernet cables of category 5 and above
◆ when using unshielded twisted pair of category 5 and above, it can supply power to up to 8 terminal devices at the same time
◆ eight standard Poe ports support IEEE802.3af (15.4W) standard and are compatible with ieee802.3at (30W)
◆ nine 10/100mbps adaptive RJ45 ports, and the power supply distance of Poe port is up to 100 meters
◆ comply with IEEE 802.3 10Base-T and IEEE 802.3u 100base TX standards
◆ flow control mode: IEEE 802.3x standard is adopted for full duplex and back pressure standard is adopted for half duplex
◆ support automatic port turnover (auto mdi/mdix), and adopt the exchange mechanism of store and forward
◆ power supply: 120W (POE port 1 ~ 8 ports), single port maximum output 30W
◆ no fan, natural heat dissipation, small, compact, quiet design, suitable for placing on the desktop or wall
◆ plug and play, without configuration, the power supply is automatically supplied to the adaptive equipment
◆ dynamic LED display makes it easy to know the working status and power supply of the port at any time
◆ through the secondary lightning protection chip design, at the same time, avoid electrostatic induction and circuit isolation protection
