About the MikroTik CRS520-4XS-16XQ-RM 2x 2.5Gb, 4x SFP28 25Gb, 16x QSFP28 100Gb Switch
The MikroTik CRS520-4XS-16XQ-RM delivers exceptional port density with 2x 2.5GbE RJ45 ports, 4x 25G SFP28 ports, and 16x 100G QSFP28 ports across a compact 1U rack form factor. This 22-port configuration achieves an aggregate switching capacity of 1.6 Tbps, positioning the CRS520-4XS-16XQ-RM as a high-performance fabric spine or core switch for modern data centre deployments. MikroTik engineered this system with redundant hot-swap power supplies and redundant hot-swap fans to ensure mission-critical uptime, while the operating temperature range of 0–40°C supports standard data centre environments.
Network architects and data centre engineers select the CRS520-4XS-16XQ-RM when they need ultra-high throughput with flexible port speeds to support both legacy and next-generation infrastructure. The combination of 100G QSFP28 uplinks, 25G SFP28 mid-tier connectivity, and 2.5G management ports enables seamless integration into tiered switching fabrics. MikroTik's comprehensive management protocols—including Telnet, SSH, WinBox, and REST API—allow IT teams to automate provisioning and monitor performance across heterogeneous network stacks. The unit ships with a lifetime hardware warranty, reducing total cost of ownership over extended deployment cycles.

Frequently Asked Questions about MikroTik CRS520-4XS-16XQ-RM 2x 2.5Gb, 4x SFP28 25Gb, 16x QSFP28 100Gb Switch
Does the MikroTik CRS520-4XS-16XQ-RM 2x 2.5Gb, 4x SFP28 25Gb, 16x QSFP28 100Gb Switch support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations before shipping, or provide remote commissioning. Add commissioning to your RFQ.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises at delivery.
Is the warranty global?
Yes — manufacturer hardware warranty is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
