Introduction JHA-P31208CBMH 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-P31208CBMH series is designed for wireless networks, security automation applications. JHA-P31208CBMH 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-P31208CBMH series of automatic identification PoE requirements, speed, duplex, and use Auto Up link TM type of cable. Features *8*10/100mbps POE port,2*10/100/1000mbps UP Link,1 Gigabit SFP Fiber Port; *250m Distance;Vlan support *Watchdog function *Supports Quality of Service (QoS) *Support IEEE802.3AF/AT *Whole Power:120W, 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.
