Introduction JHA-P420016BMH 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-P420016BMH  series is designed for wireless networks, security automation applications. JHA-P420016BMH 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-P420016BMH 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 16 10/100/1000Base-TX PoE port and 2 1000Base-FX(SFP Slot) *PoE power supply distance 100m, 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, Supports Quality of Service (QoS). *No configuration, power is automatically supplied to the adaptive equipment.   Specification PoE Feature IEEE802.3af, IEEE802.3at power with international standards PoE Parameters (Per Port) IEEE802.3af 15.4W IEEE802.3at 30W Maximum Power IEEE802.3af standard: 250W Power Line Pair Data lines 12, 36, optional spare line for 45, 78 UTP Port Parameters UTP Port: RJ45 Cable Type: Cat 5 (UTP), Cat 6 or higher Transmission distance: 100m Protocol Standards IEEE802.3i 100Base-TIEEE802.3u 100Base-TXIEEE802.3x Flow ControlIEEE802.3afIEEE802.3at Performance Specification Store and Forward Backplane Bandwidth: 52Gbps (Non-blocking) Packet Forwarding Rate: 1.19Mpps Transmission Mode: full / half duplex adaptive Addressing: 48-bit MAC address Address Database Size: 1000 MAC addresses Buffer Memory: 96Kb Delay: For 100Base-TX transmission data, 64-byte data frame delay does not exceed 20 microseconds LED Indicator Per port: speed, link indicator Per Device: Power light, PoE work lights Certification CE, FCC, RoHS Dimension 312*185*46mm ( L * W * H ) Weight 2.9KG Working Environment Operating Temperature: -10~55℃ Operating Humidity: 5%~90% Storage Temperature: -10~55℃ Storage Humidity: 5% to 90% non-condensing Certification CE, FCC, RoHS Warranty 3-years   Dimension   Order Information Model No. Description of Goods JHA-P420016BMH 16 Ports 10/100/1000M PoE Port+2 Gigabit SFP Fiber Port,build-in power supply, total:250W
