The MikroTik CRS320-8P-8B-4S+RM is MikroTik's first high-power 802.3bt PoE++ rackmount switch, specifically designed to eliminate external power injectors in modern commercial setups, hotels, stadiums, and high-rise smart buildings. Driven by a Marvell Prestera 98DX226S switch chip paired with a dual-core 800 MHz ARM processor and 256 MB RAM, it efficiently manages demanding network topologies, VLAN filtering, and hardware-offloaded Layer 3 routing without performance loss.
The switch features a versatile port configuration consisting of 8x Gigabit PoE ports (802.3af/at delivering up to 30W per port), 8x Gigabit PoE++ ports (802.3bt delivering up to 90W per port) to power resource-intensive equipment like heated outdoor 4K security cameras, digital advertising displays, and PoE lighting systems, alongside an independent Gigabit management port and 4x 10G SFP+ fiber ports for high-bandwidth backhaul. It is built inside a heavy-duty 1U steel enclosure equipped with a default 600W hot-swappable AC power supply unit and an open PSU expansion slot to increase the PoE budget up to 1150W.
Comprehensive Key Features
High-Power PoE++ (802.3bt) Ports: Equipped with 8x 802.3bt Type 3/4 PoE++ ports capable of supplying up to 90W per port alongside 8x 802.3af/at PoE ports (30W per port).
High-Bandwidth Fiber Uplinks: Includes 4x 10G SFP+ optical slots for rapid data trunking and core network interconnection.
