MicroTik Cloud Router Switch CRS309-1G-8S+IN is a very compact yet powerful network switch. It has eight SFP+ sockets, supporting up to 10 Gb/s in each of them, giving a total switching capacity of 162 Gb/s and a total unblocked capacity of 81 Gb/s.
The device also has a dual-core 800 MHz processor, 512 MB RAM, an Ethernet port with power input PoE, a serial port RS232, a ground terminal and is capable of dual boot (choose the operating system you prefer, RouterOS or SwOS). The first option allows you to use a powerful Layer2 switch, while the second allows for advanced Layer3 configuration.

RouterBOARD is a hardware platform from MikroTik, which is a line of routers with RouterOS operating system. Almost all models of RouterBOARD devices can be powered via Ethernet (PoE) and have a connector for external power source.
MikroTik RouterOS is the operating system of the router and software that allows the PC or Mikrotik RouterBoard to be a dedicated router.
PoE allows you to use a single cable for power and data transmission, saving you money on purchasing and dragging cables for network devices and VoiP phones.
