overviewrouterboard rb750gr3 is a full gigabit routerboard. it is an improved alternative routerboard rb750gl. it is ideal for internal company or home network based on gigabit elements. like rb750gl comes complete with housing and repsus.routerboard can be powered using a classical jack and poe (this is intended port 1, other ports support poe).mikrotik routeros fully supports ipv6 network and in its current form are implemented following characteristics:?? static address allocation and routing?? router advertisement daemon (the address autoconfiguration)?? dynamic routing: bgp +, ospfv3 and ripng protocol?? firewall (filter, mangle, address lists)?? dns?? 6in4 (sit) tunnels?? telnet?? ping?? traceroute?? web proxy?? sniffer tools and fetchtechnical specificationscpu nominal frequency: 880 mhzcpu core count 2threads: 4size of ram: 256mb10/100/1000 ethernet ports: 5poe in: yessupported input voltage: 6-30 vpcb temperature monitor: yesvoltage monitor: yesswitch chip model: qca8337-al3c-rdimensions: 113x89x28mmlicense level: 4operating system: routeroscpu: qca9556-r4amax power consumption: 4 wstorage type: flashstorage size: 16mbconector usb: yes! warning!manufacturer mikrotik does not warrant the equipment damaged by overvoltage. the equipment must be adequately protected against induced surges or electrostatic voltage peaks on the power line. outdoors, use only shielded cabling (ftp/sftp) and drive properly grounded through the integrated grounding member or using ethernet surge protection).
