The MikroTik CRS310-1G-5S-4S+IN is a compact cloud router switch designed to handle high-speed data traffic in professional network environments. It features a versatile port configuration, including four 10G SFP+ ports for high-bandwidth uplinks and five 1G SFP ports, complemented by a single Gigabit Ethernet port for management or local connectivity. Under the hood, an ARM v7 CPU and 256 MB of RAM support advanced networking tasks, such as Layer-3 routing and hardware-offloaded VLAN filtering, which ensures efficient traffic management without taxing the processor. This device is housed in a white metal chassis measuring 200 x 166 x 44 mm, making it suitable for both desktop placement and 1U rackmount installation. Its robust build allows it to operate in extreme environments, with a temperature range from -40°C to 70°C. For flexible power options, it supports PoE-in via the IEEE 802.3af/at standard, while a reset button and LED indicators help you monitor and maintain the system easily. Weighing 2900g, it provides a stable and reliable foundation for administrators who need a dense concentration of fiber ports in a small form factor.
