Introduction JHA-P302016CBMZH series switches provide from one network node uses Cat5 cable simultaneous transmission of data and power, when AC power is not power or take power inconvenient (such as PTZ cameras and WiMAX devices), JHA-P302016CBMZH series is designed for wireless networks, security automation applications. JHA-P302016CBMZH series switches dramatically reduces the cost of wiring the power user, wireless LAN access points, video surveillance cameras and other equipment must be spent to better support the new services and applications, providing users with a higher flexibility and mobility. Advanced self-sensing algorithm only for standard PD terminal equipment power supply, and therefore do not need to worry about damage to private or non-standard PoE PoE equipment. Simple and reliable design, JHA-P302016CBMZH series of automatic identification PoE requirements, speed, duplex, and use Auto Up link TM type of cable.   Features *16*10/100mbps POE port,2*10/100/1000mbps UP Link; *250m Distance;Vlan support *Watchdog function *Supports Quality of Service (QoS) *Support IEEE802.3AF/AT *Whole Power:250W(52V 4.8A), internal power supply; *All port supported by MDI/MDIX auto flip and self negotiation *Support IEEE802.3x flow control for Full-duplex mode and backpressure for Half-duplex mode. *Each port max. power supply reached 30W.   Specification Model 16+2 port 250m POE switch(Built-in) Model No. JHA-P302016CBMZH PoE Port 1 to 16 port support IEEE802.3af/at UP link port 17th-18th port support 1000Mbps PoE output 15.4W/30W    IEEE802.3af/at PoE whole power ≤200W PoE type End-span Power distance ≤250m Network Standard IEEE 802.3、 IEEE802.3u、802.3x、802.3af/at Network Medium 100/1000BASE-TX: 5 class and above non shielded twisted pair Data Distance ≤250m Backplane bandwidth 12Gbps Forwarding Mode Store and forward Forwarding Rate 10BASE-T:14880PPS/port100BASE-tx:14800pps/port 1001000BASE-T:1488095pps/port MAC Address 2K MAC address table Port function Power priority mechanism, fast and forward, MAC automatic learning and agingIEEE802.3X Full-duplex and mode and backpressure for Half-duplex mode Indicator LINK/ACT. 100Mbps;POE Status indicator;   POWER indicator;EXTENDER indicator Working Environment Working Temperature: -10°-- 55°C Input power AC100-240V 50/60HZ Weight 1.3kg Size 202mm*140mm*45mm(L*W*H)   Dimension   Order Information  Model No. Description of Goods JHA-P302016CBMZH 16 Ports 10/100M PoE+2 Uplink Gigabit Ethernet Port, build-in power supply,with VLAN, Watchdog function
