Introduction: These unmanaged switches are Fast Ethernet switch designed for high forwarding network environment such as school, family, SMEs and mini monitoring. It has 5 port 10/100Mbps or 10/100/1000Mbps adaptive Ethernet ports. All ports support wire-speed forwarding and the data rate is up to 100Mbps or 1000Mbps. There is 4K lightning protection to ensure smooth and stable operation. Auto MDI/MDIX is also available. No configuration is required; it will instantly operate as soon as you power it up. Features: 5*100M or 5*1000M Ethernet port with auto-negotiation functionSupport 100M/1000M speed rate,MDI/MDIXSupport IEEE802.3x Flow control and back pressure controlEach port has the complete LED Indicator light Each port supports wire-speed switching ,64~1518 frame length can reach the wire speedSupport multicast to avoid network congestionSupport 5-16V voltage inputSupport 4K lightning protection of whole device.Require no configuration and will instantly operate as soon as you power it upUse low-power consumption chips,only 2.5W in full load conditions Specification: StandardsIEEE802.3 10Base-TIEEE802.3u 100Base-TX/FXIEEE802.3x Flow controlEthernet PortConnector: RJ45Data Rate: 10/100M or 10/100/1000MDistance: 100mUTP Type: UTP-5E or higher levelPerformanceProcessing Type: Store and ForwardTransmission Mode: half/full-duplex with auto-negotiation function MAC Table Size: 1KBuffer Space: 448KBack bandwidth: 1GTime Delay: 150sPowerPower type: external power supplyInput Voltage: AC100V240V 50/60HzConnector: DC SocketWorking Voltage: 5VPower Consumption: 1.8W4WEnvironmentStorage Temperature: -4070Operating Temperature: -1055 Relative Humidity: 5-90% ( no condensation)Physical CharacteristicsDimension: 100×52×28mmWeight: 0.30kgColor: Black
