## Summary description

The Mikrotik CRS320-8P-8B-4S+RM is a network switch with 17 Gigabit Ethernet ports and Power over Ethernet capabilities. It supports IEEE 802.3af and IEEE 802.3at standards, making it ideal for powering devices over the network. Designed for rack mounting, it offers reliable performance for various networking needs.

## Long description

The MikroTik CRS320-8P-8B-4S+RM is a rack-mount Gigabit Ethernet switch with 17 RJ-45 ports and Power over Ethernet (PoE) functionality. It implements full 802.3af/at/bt standards, provides a built-in hot-swappable 600 W power supply with an expansion slot for an additional PSU, and includes four 10G SFP+ fiber uplink ports and a console port. The switch uses a Marvel switching chip capable of hardware-offloaded Layer-3 routing and VLAN filtering, designed to support demanding PoE deployments in hotels, conference halls, offices and high-rise buildings.
Advantages
The CRS320 delivers up to 90 W per port on 802.3bt PoE++ ports and combines 802.3af/at and 802.3bt support in a single unit, reducing the need for separate DC power adapters. With 17 Gigabit Ethernet ports (eight standard PoE ports, eight PoE++ ports and one management port), four 10G SFP+ uplinks, a reliable Marvel switch chip and a hot-swappable 600 W PSU plus an expansion slot for increased total power, the switch offers robust power capacity and flexible connectivity for complex installations.
Suitable for
 Powering high-consumption PoE devices such as 4K security cameras with heaters
 PoE-powered LED advertising screens and lighting fixtures
 Network distribution in hotels, conference centers and office buildings
 Rack-mounted deployments requiring multiple 10G uplinks
Key specifications
 Model: MikroTik CRS320-8P-8B-4S+RM (MPN CRS320-8P-8B-4S+RM)
 Ethernet ports: 17 × Gigabit RJ-45 (ports #1–#8 PoE-out 802.3af/at, #9–#16 PoE++ 802.3bt, +1 management port)
 Fiber uplinks: 4 × 10G SFP+
 PoE power per port: up to 90 W on 802.3bt ports
 Included PSU: 600 W hot-swappable (expansion slot for additional PSU, total up to 1150 W possible)
 Chipset: Marvel switching chip with hardware-offloaded Layer-3 routing and VLAN filtering
 Standards: IEEE 802.3af, IEEE 802.3at, IEEE 802.3bt (full implementation)
How to use
Install the CRS320 in a standard 19" rack using the provided mounting hardware. Connect your uplink to one of the 10G SFP+ ports and attach devices to the Gigabit RJ-45 ports; the switch will negotiate PoE with compatible Powered Devices. Use the dedicated management port or the console port to perform initial configuration and to set up VLANs or Layer-3 routing. If higher total PoE capacity is required, install an additional compatible PSU in the expansion slot to increase the available power up to the rated maximum.
Usage recommendations
Only connect fully compliant 802.3af/at/bt Powered Devices where possible. While the CRS320 can power some compatible devices that claim 802.3af/at/bt compatibility, avoid certain grounding scenarios described in the official MikroTik Help pages to prevent issues. Refer to the manufacturer documentation for safe installation and grounding practices.
