2. Official Product Overview

The Cisco CBS350-24XTS is a pure 10-Gigabit hybrid copper-fiber fully managed enterprise Layer 3 switch within Cisco Business 350 global portfolio. The suffix XTS stands for mixed 10G Twisted-pair copper + 10G SFP+ fiber ports, all interfaces run at 10G speed, no Gigabit-only access ports, no PoE support. It is designed for medium enterprise high-performance workstation aggregation, media production studios, multi-building campus 10G fiber backbone, optical storage aggregation and high-bandwidth surveillance core environments without PoE power requirements.

Distinct from entry CBS250 smart switches, CBS350 delivers complete enterprise-grade managed capabilities: dynamic RIPv2 Layer 3 routing, true single-IP stacking (up to 4 units), comprehensive anti-spoofing security suite, sFlow traffic analytics and full-featured multicast control. This all-10G hybrid switch eliminates bandwidth bottlenecks, supporting 10G copper low-latency workstations and long-distance 10G single/multi-mode fiber interconnection between buildings and remote server rooms.

It features 12×10GBase-T RJ45 copper access ports + 12×dedicated 10G SFP+ fiber access ports, total 24×10G wire-speed interfaces, no separated uplink slots — all ports are universal 10G ports for flexible access, aggregation and stacking link deployment. Powered by an 800MHz ARM processor with 512MB DRAM and 256MB flash memory, it delivers 480 Gbps non-blocking switching capacity and 357.14 Mpps wire-speed forwarding rate for 64-byte frames, equipped with a 3MB shared dynamic packet buffer to eliminate congestion under 8K video editing, bulk multi-TB storage transfers and mass 10G multi-camera streaming traffic. Optimized triple variable-speed fan cooling ensures stable 24/7 continuous rack operation in core data rooms and media production racks.
