The MikroTik 8-Port Gigabit Ethernet 802.3af/at PoE Switch with 4x SFP ports is a versatile, high-performance PoE network switch designed to simplify modern business and retail networking. Ideal for New Zealand offices, hospitality venues, and multi-device retail environments, it delivers fast Gigabit connectivity while powering compatible devices over Ethernet to reduce cabling and tidy up installations. With a practical mix of copper ports and SFP uplinks, it’s a smart choice for reliable LAN expansion, IP camera deployments, VoIP phones, and wireless access points.

  • Power and data over one cable: Supports IEEE 802.3af/at PoE to power devices like access points, IP cameras, and VoIP phones while keeping installations neat and efficient.

  • Fast, dependable Gigabit performance: Eight Gigabit Ethernet ports help maintain responsive connections for POS systems, staff devices, and bandwidth-heavy applications.

  • Flexible uplinks with 4x SFP: Four SFP ports provide fibre or uplink options for longer runs and cleaner network design between cabinets, floors, or buildings.

  • Practical scalability for growing sites: A strong fit for expanding networks where reliable PoE switching and efficient connectivity are essential.

This switch 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.

A 28V 3.4 A power supply is already included in the box and there is secondary DC jack on the back of the enclosure that supports an optional 48-57 V power supply for power redundancy (order SKU: PS28V3.4A)

Then 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
