Product overview

The Mikrotik CRS320-8P-8B-4S+RM is a high-performance managed PoE++ switch engineered for enterprise deployments requiring extensive power delivery to networked devices. This switch combines 16 Gigabit Ethernet ports with four 10G SFP+ fiber uplinks, delivering 4.6Tbps Layer 2 switching capacity and non-blocking throughput. The device provides 963W total PoE output across two port groups: ports 1-8 support IEEE 802.3af/at (up to 30W per port), while ports 9-16 support IEEE 802.3bt (up to 90W per port). Built on a dual-core ARM 800MHz processor with 256MB RAM and 32MB Flash storage, it runs RouterOS v7 with full Layer 2 switching and VLAN filtering capabilities. The switch includes intelligent PoE controller, three cooling fans, and operates across 100-240V AC input with maximum 1150W power consumption when dual PSUs are installed. Ideal for powering IP cameras, wireless access points, VoIP systems, and industrial IoT devices in data centers, campuses, and edge deployments.
