MikroTik CRS317-1G-16S+RM 16-Port 10G SFP+ Managed Switch | 1× Gigabit, Dual PSU, 1U Rackmount, 1GB RAM

MikroTik CRS317-1G-16S+RM 16-Port 10G SFP+ Managed Switch

The MikroTik CRS317-1G-16S+RM is a high-density 10 Gigabit managed switch designed for enterprise networks, data centers, server environments, storage infrastructure and high-speed network aggregation. It provides 16 × 10G SFP+ ports and 1 × 10/100/1000 Gigabit Ethernet port for management and network connectivity.

Built around the Marvell Prestera 98DX8216 switching platform, the CRS317 is designed to deliver high-speed Layer 2 switching across all sixteen SFP+ interfaces. It supports both MikroTik RouterOS and SwOS, allowing administrators to choose between a full-featured routing and switching environment or a dedicated switch operating system.

16× 10G SFP+ Ports

The primary feature of the CRS317-1G-16S+RM is its 16 high-speed SFP+ interfaces. Each port supports 10Gbps SFP+ connectivity and can also accept compatible 1.25Gbps SFP modules.

• 16 × 10G SFP+ ports
• Support for compatible 1.25G SFP modules
• 10Gbps fiber connectivity
• DAC and AOC connectivity with compatible cables
• DDMI support for compatible optical modules
• 1 × 10/100/1000 Gigabit RJ45 management port

This high port density allows the CRS317 to connect multiple servers, storage systems, routers, aggregation switches and other 10GbE devices without requiring separate switches for each group of high-speed connections.

High-Density 10G Network Aggregation

With sixteen SFP+ ports, the CRS317-1G-16S+RM can serve as a central 10G aggregation switch in a network architecture. Multiple 10G servers, storage systems and access-layer switches can be connected directly to the SFP+ interfaces.

The remaining Gigabit Ethernet port can be used for management or an additional copper network connection. This makes the switch particularly useful in installations where the majority of network links are based on 10G fiber or direct-attach connectivity.

Wire-Speed Layer 2 Switching

The CRS317 is built around the Marvell Prestera 98DX8216 switch chip. MikroTik’s published non-blocking Layer 2 test results show approximately 158.9Gbps throughput and approximately 317.8Gbps switching capacity with 1518-byte frames under the specified test methodology.

The manufacturer also publishes approximately 161Gbps Layer 1 throughput and 322Gbps Layer 1 switching capacity in its non-blocking test configuration. These are laboratory measurements and actual application performance depends on traffic patterns, packet sizes and enabled features.

RouterOS and SwOS Dual Boot

The CRS317-1G-16S+RM supports both RouterOS and SwOS. The switch can boot into either operating system according to the requirements of the network.

SwOS provides a focused switch-management environment for Layer 2 deployments, while RouterOS provides additional routing and networking functionality. The operating system can be selected through the device configuration.

Advanced Layer 2 Features

The CRS317 supports professional switching features for enterprise and data-center networks.

• IEEE 802.1Q VLAN
• Hardware-based VLAN processing
• Spanning Tree Protocol
• Rapid Spanning Tree Protocol
• Multiple Spanning Tree Protocol
• Link Aggregation Control Protocol (LACP)
• Port isolation
• Port security
• Access Control Lists
• Broadcast storm control
• Port mirroring
• Bandwidth limitation
• IGMP Snooping
• SNMP v2/v3

The switch supports up to 4,000 simultaneous VLANs according to MikroTik’s published product documentation.

10G Fiber and Direct-Attach Connectivity

The SFP+ architecture allows the CRS317 to be deployed with different physical connectivity options. Depending on distance and network design, administrators can use compatible optical SFP+ transceivers, fiber patching, direct-attach copper cables or active optical cables.

For short server-to-switch or switch-to-switch connections inside a rack, compatible DAC cables can provide a practical 10G connection. For longer links, appropriate optical transceivers and fiber can be used.

Dual Redundant Power Supplies

The CRS317-1G-16S+RM includes two AC power inputs and two PSU slots. The redundant power architecture is designed to improve availability in professional network environments.

The device accepts 100–240V AC input and has a maximum specified power consumption of approximately 44W. One PSU can operate the unit while the second provides redundancy.

Passive Cooling with Automatic Fans

The CRS317 uses a large passive cooling system for normal operation. Under elevated temperatures, its redundant fans can automatically activate to maintain appropriate operating conditions.

This hybrid cooling design allows the switch to remain quiet during normal operation while retaining active cooling capability when required. MikroTik specifies a tested ambient operating range of -20°C to +60°C.

1U Rackmount Design

The CRS317-1G-16S+RM is designed for professional rack installations and occupies a standard 1U rack space. The chassis measures approximately 443 × 224 × 44 mm.

Rack ears and required mounting accessories are included, allowing the switch to be installed alongside servers, routers, fiber panels, UPS systems and other rack-mounted network equipment.

10G Server and Storage Networks

The sixteen SFP+ ports make the CRS317 suitable for environments where many servers and storage systems require 10Gbps connectivity.

Typical examples include virtualization clusters, NAS and storage networks, backup infrastructure, high-performance workstations, database servers and private data-center networks.

Enterprise and Data Center Applications

The combination of high-density 10G connectivity, hardware-based switching, VLAN support, LACP, redundant power and RouterOS/SwOS dual boot makes the CRS317 suitable for professional network deployments.

• Data center 10G aggregation
• Enterprise network backbone
• Server aggregation
• NAS and storage networks
• Virtualization infrastructure
• ISP and service-provider networks
• High-speed campus networks
• 10G fiber distribution
• Switch-to-switch 10G aggregation
• Network laboratory environments
• High-performance computing infrastructure

1G Management Port

In addition to its sixteen SFP+ interfaces, the CRS317 includes one 10/100/1000 Gigabit RJ45 Ethernet port. This port is commonly used for management access and can be connected to a conventional copper Ethernet network.

Having a dedicated copper management interface means that the sixteen SFP+ ports can remain available for high-speed network connections.

RouterOS Layer 3 Capabilities

When operated with RouterOS, the CRS317 can provide more than conventional Layer 2 switching. RouterOS enables advanced routing and network-management functionality supported by the hardware and software configuration.

Depending on the deployment, administrators can use features such as VLAN routing, firewall policies, IP routing, network monitoring and other RouterOS functions.
