Introduction JHA-P322024CBTH 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-P322024CBTH series is designed for wireless networks, security automation applications. JHA-P322024CBTH 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-P322024CBTH series of automatic identification PoE requirements, speed, duplex, and use Auto Up link TM type of cable.   Features *Use unshielded twisted pair can combine up to four power supply terminal equipment. *Support 24 10/100Base-TX PoE port,2 10/100/1000mbps UP Link,2 Gigabit SFP Fiber Port; *PoE power supply distance 250m. *Support IEEE802.3 af (15.4W) and IEEE802.3 at (30W) PoE standard. *Dynamic LED for easy status at any time for the port to work with the power supply situation. *Through the secondary lightning protection chip design, while avoiding electrostatic induction, circuit isolation protection Plug and Play. *No configuration, power is automatically supplied to the adaptive equipment.    Specification Model 24+2+2 port 250m POE switch(Built-in) Model No. JHA-P322024CBTH PoE Port 1 to 24 port support IEEE802.3af/at UP link port 25th-26th port support 1000Mbps Fiber Port 1000M Fiber port PoE output 15.4W/30W    IEEE802.3af/at PoE whole power ≤400W 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 Switch capability 12Gbps Forwarding Mode Store and forward Forwarding Rate 100Mbps:14880pps 1000Mbps:14800pps 1000BASE-T: 1488095pps/port MAC Address 2K MAC address table Port function Power priority mechanism, fast and forward, MAC automatic learning and aging IEEE802.3X 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 4kg Size 440mm*285mm*55mm(L*W*H)   Dimension   Order Information  Model No. Description of Goods JHA-P322024CBTH 24 Ports 10/100M PoE+2 Uplink Gigabit Ethernet Port+2 Gigabit SFP Fiber Port,build-in power supply,total 400W, 1U Type.
