Overview:

MikroTik CRS320-8P-8B-4S+RM 16 Port Gigabit PoE++ Cloud Router Switch
The MikroTik CRS320-8P-8B-4S+RM is a high-power managed PoE++ switch designed for networks that need reliable power delivery, high-speed uplinks and efficient cable management. With support for 802.3af, 802.3at and 802.3bt PoE standards, it can provide up to 90W per port for demanding devices such as security cameras, LED lighting, wireless access points and other network equipment. Four 10G SFP+ ports provide fast fibre uplink connectivity, while hardware-offloaded Layer 3 routing and VLAN filtering help the switch handle demanding network workloads.

Description:

The CRS320-8P-8B-4S+RM brings high-power PoE++ to business, industrial and commercial networks in a rackmount design. Instead of running separate power cables and adapters to every powered device, compatible equipment can receive both network connectivity and electrical power through Ethernet.

Eight Gigabit Ethernet ports support 802.3af/at PoE output, while another eight Gigabit Ethernet ports support 802.3bt PoE++ for higher-power equipment. An additional Gigabit Ethernet port is available for management, giving the switch a total of 17 Gigabit Ethernet ports. Four 10G SFP+ ports allow high-bandwidth fibre uplinks to the network core or other switches.

The CRS320 is particularly well suited to environments such as hotels, offices, conference facilities, high-rise buildings and security installations. It can supply up to 90W per PoE++ port, making it suitable for equipment that requires more power than conventional PoE can provide.

The included 600W power supply provides substantial capacity, while a second PSU slot allows the available power budget to be expanded to as much as 1150W when additional capacity is required. The PSU is also hot-swappable, helping simplify maintenance in installations where network availability is important.

Features:

High-Power PoE++ for Demanding Devices
The CRS320-8P-8B-4S+RM is MikroTik's first switch with full 802.3af/at/bt PoE support. This makes it possible to consolidate network connectivity and power delivery through a single Ethernet connection.

Potential applications include:

• 4K security cameras with built-in heating elements
• High-power wireless access points
• PoE-powered LED lighting
• Digital and LED advertising displays
• Commercial and industrial network equipment
• Hotel and conference room installations

With up to 90W available from a PoE++ port, the switch can power devices that exceed the limits of standard PoE and PoE+.

17 Gigabit Ethernet Ports and 10G SFP+ Uplinks
Connectivity is built around 17 Gigabit Ethernet ports. Ports 1 through 8 provide 802.3af/at PoE output, while ports 9 through 16 support 802.3bt PoE++. The additional Gigabit Ethernet port can be used for management.

For faster network connections, four 10G SFP+ ports are included for fibre or compatible high-speed uplinks. A dedicated console port is also available for management and configuration.

Power Capacity and Rackmount Design
A 600W power supply is included, providing the capacity needed for high-power PoE deployments. The CRS320 also includes a second PSU slot, allowing the total power output to be increased to up to 1150W with the appropriate additional power supply.

The rackmount format makes the switch suitable for structured network cabinets and professional installations where space, cable organisation and centralised power delivery are important.

Hardware-Accelerated Networking
At the centre of the CRS320 is a Marvell switch chip designed to handle demanding network traffic efficiently. Hardware acceleration supports functions such as VLAN filtering and Layer 3 routing, helping reduce processing overhead while maintaining strong network performance.

This makes the switch suitable not only for powering devices but also for managing more advanced network configurations in business and infrastructure environments.

Designed for Cleaner Cable Management
One of the main advantages of the MikroTik CRS320 is the reduction in separate power cabling. Compatible PoE devices can receive power directly through their network cables, reducing the need for individual DC power adapters and helping create a cleaner installation.

This is particularly useful in offices, hotels, conference venues, security systems and larger buildings where multiple powered network devices are installed throughout the premises.

802.3af, 802.3at and 802.3bt Compatibility
The CRS320 supports the full 802.3af/at/bt PoE standard and is intended for fully compliant Powered Devices. It can support compatible MikroTik equipment and other compliant PoE devices, although certain grounding configurations should be considered when using devices described as only "802.3af/at/bt-compatible".

The included hot-swappable PSU adds another practical advantage for professional deployments, allowing the power supply to be replaced without requiring the entire switch to be removed from service.

MikroTik CRS320-8P-8B-4S+RM for Professional Networks
For installations that require high-power PoE, 10G uplinks and advanced network management, the MikroTik CRS320-8P-8B-4S+RM provides a centralised solution. Its combination of 802.3bt PoE++, 10G SFP+ connectivity, hardware-accelerated switching, Layer 3 routing and expandable power capacity makes it a strong choice for demanding business and infrastructure networks.
