## Long description

The Mikrotik CRS320-8P-8B-4S+RM is a rack-mount Gigabit Ethernet switch with integrated Power over Ethernet (PoE) support. It provides 17 Gigabit Ethernet ports including eight standard PoE (802.3af/at) ports, eight PoE++ (802.3bt) ports, a dedicated management Ethernet port, four 10G SFP+ uplink ports and a console port. The switch includes a hot-swappable 600 W power supply with an expansion slot for an additional PSU to increase total power capacity.
Advantages
The CRS320-8P-8B-4S+RM supplies up to 90 W per PoE port on 802.3bt ports and supports hardware-offloaded Layer-3 routing and VLAN filtering thanks to a high-performance Marvel switch chip. Its PoE++ capability and 17 Gigabit ports simplify cable management by reducing the need for external power adapters. The device is rack-mountable and designed for stable, continuous operation with a removable power supply and optional PSU expansion.
Suitable for
Hotel and hospitality networks requiring centralized PoE power
Conference halls and office buildings with PoE cameras, LED displays and lighting
Multi-floor and high-rise installations where centralized power management is needed
