Introduction JHA-P420024BTH 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-P420024BTH series is designed for wireless networks, security automation applications. JHA-P420024BTH 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-P420024BTH 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 10/100/1000Base-TX PoE port and 2 1000Base-FX(SFP Slot) *PoE power supply distance 100m.Supports,Watchdog function *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, Quality of Service (QoS). *No configuration, power is automatically supplied to the adaptive equipment.    Specifications:   Product 24+2 Port SFP Port POE Switch (Built-in) Model JHA-P420024BTH POE Port 1 to 24 support IEEE802.3AF/AT Standard Fiber Port 1000M fiber port Output Power 15.4W/30W    IEEE802.3af/at Power Pin Both 1/2+、3/6- and 4/5+7/8- Whole Power ≤400W POE Protocol IEEE 802.3af/IEEE 802.3at POE Type End-span Power Distance ≤100m Network Standard IEEE 802.3、 IEEE802.3u、802.3x、802.3af/at Network Medium 10/100BASE-TX:5 class and above non shielded twisted pair Data Distance ≤100m Switch Capability 56Gbps Forwarding Mode Store and forward Forwarding Rate 100BASE-tx:14800pps/port1000BASE-tx:1488095pps/port MAC Address MAC address table 16K Port Function Power priority mechanism, fast and forward, MAC automatic learning and agingIEEE802.3X Full-duplex and mode and backpressure for Half-duplex mode LED Indicator Each port occupied 1 LINK/ACT.100Mbps,POE Status Indicator, Whole power indicator Working Environment Working temperature：-10°-- 55°C Weight 3.5kg Size 310mm*182mm*45mm(L*W*H)   Dimension Order Information:  Model No. Description of Goods JHA-P420024BTH 24 Ports 10/100/1000M PoE Port+2 Gigabit SFP Fiber Port,build-in power supply, total:400W
