Introduction JHA-P40104BMH 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-P40104BMH series is designed for wireless networks, security automation applications. JHA-P40104BMHseries 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 equipment. Simple and reliable design, JHA-P40104BMHseries of automatic identification PoE requirements, speed, duplex, and use Auto Up link TM type of cable.   Features *4*100/1000mbps POE port;1*100/1000mbps UP Link port; *100m Distance *Supports Quality of Service (QoS) *Support IEEE802.3AF/AT, Support Vlan. *Watchdog function *Whole Power:72W, internal power supply *All port supported by MDI/MDIX auto flip and self negotiation *Supply 4 100/1000Mpbs adaptive high speed forwarding data packet non-lost port. *Support IEEE802.3x flow control for Full-duplex mode and backpressure for Half-duplex mode. *Each port max. power supply reached 30W.   Specification Product 4+1 Port POE Switch (Built-in) Model JHA-P40104BMH POE Port 1 to 4 support IEEE802.3AF/AT Standard UP link port 5th port support 1000Mbps Output Power 15.4W/30W    IEEE802.3af/at Power Pin Both 1/2+、3/6- and 4/5+7/8- Whole Power ≤72W 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 12Gbps Forwarding Mode Store and forward Forwarding Rate 100BASE-tx:14800pps/port1000BASE-T: 1488095pps/port MAC Address MAC address table 2K 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 1.5kg Size 202mm*140mm*45mm(L*W*H)   Dimension Order Information  Model No. Description of Goods JHA-P40104BMH 4 Ports 10/100/1000M PoE + 1 Uplink Gigabit Ethernet Port,build-in power supply,with VLAN
