The MikroTik RB5009UG+S+IN is a powerful router designed for demanding network environments that require high throughput and stability. At its core, it features a Marvell Armada quad-core ARMv8 processor clocked at 1.4 GHz, supported by 1GB of DDR4 RAM and 1GB of NAND storage, ensuring smooth operation even under heavy loads. Connectivity is extensive, offering seven standard Gigabit Ethernet ports, one 2.5 Gigabit Ethernet port for faster wired connections, and a 10G SFP+ cage for high-speed fiber uplinks. A USB 3.0 Type A port is also available for expanding functionality. Its physical design is focused on efficiency and durability, with a black chassis that doubles as a heat-sink to keep the CPU and switch-chip cool without needing active fans. Measuring 220 x 125 x 22 mm and weighing 945 g, the device is compact yet sturdy, and it can be mounted in a rack where four units fit into a single 1U space. It supports a wide operating temperature range from -40 °C to 60 °C, making it reliable in various environments. Powering the unit is flexible, as you can use the DC jack, a 2-pin terminal, or PoE-in via the first Ethernet port following the IEEE 802.3af/at standard.
