MikroTik CRS320‑8P‑8B‑4S+RM PoE++ 16-Port Gigabit Switch

The MikroTik CRS320‑8P‑8B‑4S+RM PoE++ 16-Port Gigabit Switch is a powerful Layer 2+ cloud router switch designed for modern enterprise and industrial-grade PoE++ deployments. Featuring 16 PoE-out Gigabit Ethernet ports, including 8 full 802.3bt PoE++ (up to 90W) outputs and 4×10G SFP+ uplink ports, it is ideal for powering power-hungry devices such as PTZ cameras, Wi-Fi 6 APs, LED displays, and smart controllers.

The switch is powered by a robust dual-core ARM CPU, 256 MB RAM, dual-boot OS (RouterOS and SwitchOS), and supports a combined PoE output capacity of up to 963W. With a hot-swappable PSU and optional secondary PSU slot, intelligent fan cooling, and rackmount-ready 1U design, this unit delivers exceptional performance, flexibility, and efficiency for high-demand networks.
