MikroTik CRS317-1G-16S+RM 16-Port 10GbE SFP+ Layer 3 Switch

The MikroTik CRS317-1G-16S+RM is a rack-mountable, Layer 3 managed switch engineered for high-density 10GbE fiber deployments. Driven by the 98DX8216 switching chip and a dual-core ARM 32-bit CPU running at 800 MHz, the unit delivers wire-speed switching performance across all sixteen SFP+ ports regardless of Ethernet frame size. Hardware-based Spanning Tree Protocol and Link Aggregation (LACP) extend enterprise-grade resiliency and port-channel flexibility to demanding network environments. Dual redundant AC power supplies and a passive cooling chassis—augmented by two auto-activating redundant fans for elevated ambient conditions—ensure continuous availability in data center and high-density edge deployments. The device runs MikroTik RouterOS (License 6) or SwitchOS, providing a familiar, feature-rich management experience for network engineers already invested in the MikroTik ecosystem.

Key features & benefits

• Wire-Speed 10GbE on All 16 SFP+ Ports — The 98DX8216 next-generation switching chip sustains line-rate throughput across every SFP+ port at any Ethernet frame size, eliminating bottlenecks in high-throughput aggregation or core switching roles.
• Layer 3 Switching Capability — Full Layer 3 feature support enables inter-VLAN routing and advanced traffic management directly on the switch, reducing reliance on dedicated router hardware in tiered network architectures.
• Hardware-Based STP and LACP — Spanning Tree Protocol and Link Aggregation Control Protocol are offloaded to hardware, delivering deterministic loop protection and bonded uplinks without taxing the CPU.
• Dual Redundant Power Supplies — Two independent AC inputs spanning 100–240 V provide power redundancy, protecting against single-supply failures in mission-critical environments.
• Adaptive Passive and Active Cooling — The passively cooled chassis keeps acoustics low under normal loads; two redundant fans activate automatically when ambient temperatures rise, maintaining reliability up to 60°C.
• Dedicated 1GbE Copper Management Port — An out-of-band 10/100/1000 Ethernet copper port isolates management traffic from production data planes, simplifying access control and troubleshooting.
• RouterOS / SwitchOS Dual Operating System — Operators can run RouterOS License 6 for full router-feature depth or SwitchOS for a streamlined switching-focused interface, giving teams flexibility to match their operational workflows.
• RJ45 Serial Console Port — A dedicated serial console port enables direct CLI access for initial provisioning, firmware recovery, or out-of-band management without dependency on the network.
