MikroTik CRS320-8P-8B-4S+RM – High-Power PoE++ Managed Switch
MikroTik CRS320-8P-8B-4S+RM is a professional 1U rackmount managed switch designed for high-power PoE deployments, enterprise networks, surveillance infrastructure, wireless access points, VoIP devices and other Ethernet-powered equipment. It combines 16 Gigabit Ethernet ports with PoE-Out and 4× 10G SFP+ ports for high-speed fiber uplinks and network aggregation.
The CRS320-8P-8B-4S+RM is MikroTik’s high-power PoE++ switch, supporting standard IEEE 802.3af, 802.3at and 802.3bt PoE standards. Eight Ethernet ports support 802.3af/at PoE-Out, while another eight ports support 802.3bt PoE-Out, making the switch suitable for powering a wide range of network devices from a centralized rack location.
16× Gigabit Ethernet Ports with PoE-Out
The switch provides 16× 10/100/1000 Mbps Gigabit Ethernet ports. All 16 copper Ethernet ports support PoE-Out, allowing compatible powered devices to receive both network connectivity and electrical power through a single Ethernet cable.
- Ether1–Ether8: IEEE 802.3af/at PoE-Out
- Ether9–Ether16: IEEE 802.3bt PoE-Out
- Ethernet speed: 10/100/1000 Mbps
- PoE management: Smart PoE controller
This port arrangement makes the CRS320 particularly useful for deployments combining conventional PoE devices with higher-power PoE++ equipment.
802.3af/at/bt PoE++ Support
One of the key features of the MikroTik CRS320-8P-8B-4S+RM is its high-power PoE capability. The switch supports 802.3af, 802.3at and 802.3bt, allowing it to power compatible devices such as wireless access points, IP cameras, VoIP phones and other PoE-enabled network equipment.
MikroTik specifies up to 963W total PoE output power. The maximum output current is specified at 17.82A, while the maximum per-port output is up to 560mA for 802.3af/at ports and up to 1667mA for 802.3bt ports under the specified input conditions. Actual available power depends on the power supply configuration and connected-device requirements.
Important: the total PoE budget should not be confused with the maximum power available from an individual port. The connected devices and their PoE class determine the power they can draw.
4× 10G SFP+ Fiber Uplinks
For high-speed backbone and aggregation connectivity, the CRS320 includes 4× 10G SFP+ ports. These interfaces support compatible 1G, 2.5G and 10G SFP/SFP+ modules depending on the selected transceiver and network configuration.
The SFP+ ports can be used for fiber uplinks to core switches, servers, aggregation switches, storage networks or other high-bandwidth network infrastructure. Using fiber uplinks can also help separate high-volume backbone traffic from the Gigabit access layer.
Designed for Enterprise and Surveillance Networks
With 16 Gigabit PoE ports and four 10G SFP+ uplinks, the MikroTik CRS320-8P-8B-4S+RM can serve as an access or aggregation switch for networks where multiple powered devices need to connect to a centralized rack.
Typical applications include:
- Enterprise PoE access networks
- IP surveillance and CCTV deployments
- Wi-Fi 6 and Wi-Fi 7 access point installations
- VoIP and IP telephony networks
- High-power PoE++ infrastructure
- ISP and WISP access networks
- Campus networking
- Industrial Ethernet deployments
- Network aggregation with 10G fiber uplinks
- Server and storage network connectivity
RouterOS v7 with SwOS Dual-Boot Support
The CRS320-8P-8B-4S+RM runs RouterOS v7 and can also be configured to boot into SwOS. MikroTik documentation specifies RouterOS version 7 or above, with dual-boot to SwOS available through the RouterOS menu.
RouterOS provides the broader MikroTik networking environment, including advanced switching, VLAN, routing, firewall and management capabilities. SwOS provides a simpler switch-focused management interface for deployments where advanced RouterOS functionality is not required.
Layer 3 Hardware Offloading
The CRS320 uses the Marvell 98DX226S switch chip and supports Layer 3 hardware offloading for supported RouterOS functions. Hardware offloading allows eligible traffic and routing operations to be handled by the switch chip, reducing CPU involvement for those functions.
The actual performance of a configured network depends on the selected features, routing design, packet sizes, traffic patterns and RouterOS configuration.
High-Capacity Internal Power System
The CRS320 is designed around a high-power AC power architecture to support its substantial PoE budget. The unit accepts 100–240V AC input and is supplied with a 636W hot-swappable IEC power supply. A second matching hot-swappable power supply can be installed for increased power capacity and redundancy.
MikroTik specifies maximum power consumption of approximately 36W without connected PoE devices. Under maximum load, consumption can reach approximately 600W with one PSU and up to 1150W with the additional PSU configuration.
1U Rackmount Design
The CRS320-8P-8B-4S+RM uses a standard 1U rackmount form factor, making it suitable for professional network racks and server rooms. Rackmount ears are included for installation in a compatible rack enclosure.
The device is intended for indoor installation and should be placed in a dry, properly ventilated environment. MikroTik specifies an IP20 enclosure and an operating temperature range of approximately 0°C to +60°C in its current quick guide.

MikroTik CRS320-8P-8B-4S+RM for CCTV and IP Cameras
The CRS320 is suitable for centralized PoE distribution in IP surveillance networks. Its 16 Gigabit PoE-Out ports can provide network connectivity and power to compatible IP cameras, while the four 10G SFP+ ports can provide high-speed uplinks toward the core network or recording infrastructure.
For surveillance deployments, the actual PoE requirement should be calculated based on the camera models, IR illumination, heaters, motors and other connected accessories. The total PoE requirement should remain within the available switch power budget.
MikroTik CRS320 for Wi-Fi Access Points
The high PoE capacity of the CRS320 makes it suitable for powering professional wireless access points. Standard 802.3af/at devices can be connected to the first eight PoE ports, while compatible 802.3bt devices can use the higher-power PoE++ ports.
This can simplify enterprise Wi-Fi deployments by reducing the need for separate power adapters and individual power cables at every access-point location.
10G Fiber Uplink for High-Bandwidth Networks
The four 10G SFP+ interfaces allow the CRS320 to connect to high-speed network infrastructure. A typical architecture can use Gigabit PoE ports for edge devices and 10G SFP+ ports for uplinks toward a core switch, server, storage system or aggregation layer.
Actual 10G link performance depends on the SFP+ module, fiber or DAC cable, connected equipment and network configuration.
