This switch supports PoE (Power over Ethernet) technology, allowing compatible devices to be powered directly via network cables, simplifying the deployment of IP cameras, wireless access points, and other equipment in professional settings. Its white plastic housing measures 20 x 14.3 x 4 cm, making integration into various spaces easy without sacrificing durability. It operates with a maximum power consumption of just 10 W, ensuring efficiency and low operating costs. Equipped with a 400 MHz processor and 128 MB internal memory, managed by RouterOS L5, a system known for advanced network configuration and management. Compliant with IEEE 802.3af and 802.3at standards, it ensures compatibility with a wide range of devices and business solutions. The operating range supports temperatures from -20 to 60 °C, making it a reliable choice even in demanding industrial environments. It also includes a power adapter and operates with an input voltage between 18 and 57 V DC, adding installation versatility. In summary, the Mikrotik CRS112-8P-4S-IN is the ideal solution for small and medium businesses seeking advanced connectivity, energy efficiency, and easy management for their professional networks.
CRS112-8P-4S-IN is an eight Gigabit RJ45 port PoE switch, that offers different power output options: autosensing 802.3af/at PoE/PoE+ and Passive PoE, and four SFP ports provide optical fiber connectivity options to support uplinks of up to 1 Gbps. CRS112-8P-4S-IN is equipped with 12 independent switching ports. 28 V 3.4 A power supply is already included in the box. There is secondary DC jack on the back of the enclosure that supports 48-57 V power supply (not included, can be purchased separately). CRS112-8P-4S-IN can power 802.3af/at devices if 48-57 V DC input is used (unit will automatically detect and provide correct power to devices). Max current is 1 A per port if input voltage is 18-28 V, 450 mA if 48-57 V. Total limit is 2.8A@24V and 1.4A@48-57V. PoE-Out is passed over mode B 4,5 (+) and 7,8 (-) pins
