Cisco CBS350X-24T-4X Business 350X Series 24-Port Gigabit Non-PoE Fully Managed Layer 3 Switch, Global Standard Version, 4 Dedicated 10G SFP+ High-Speed Uplink Slots (4X = four 10G fiber uplinks, distinct from 4G 1G SFP uplink models), Dual-Stack IPv4/IPv6 Dynamic Routing, Enhanced True Stacking, 1RU Rackmount Mid-Density Gigabit Access 10G Uplink Aggregation Switch

2. Official Product Overview

The Cisco CBS350X-24T-4X is an upgraded mid-density non-PoE enterprise-class fully managed Layer 3 switch within the Cisco Business 350X high-performance switch portfolio, an enhanced variant of the standard CBS350 series with optimized hardware throughput, faster stacking performance and upgraded thermal architectureCisco.

Model suffix breakdown:

• T: 24×10/100/1000BASE-T Gigabit copper access ports, zero PoE power delivery
• 4X: Four independent dedicated 10G SFP+ fiber uplink ports for high-bandwidth 10-Gigabit backbone backhaul, clearly separated from 4G variants equipped with only 1G SFP uplink interfaces.

Designed for medium enterprise office access layers, multi-floor building wiring closets, retail back-office data networks, and NAS storage aggregation environments without PoE-powered endpoints. Compared with base CBS350 and entry-level CBS250 smart switches, the CBS350X delivers enhanced enterprise-grade managed capabilities: high-speed true single-IP stacking (up to 4 CBS350X units with faster stack interconnects), dynamic RIPv2 Layer 3 routing, comprehensive anti-spoofing security suite, sFlow traffic analytics and complete multicast traffic control.

This copper-only Gigabit access switch optimizes standard office data transmission for desktop workstations, POS terminals, standalone Wi-Fi 6/6E wireless access points and centralized storage servers, while four standalone 10G SFP+ slots provide high-speed redundant fiber uplinks to core network switches for cross-building long-distance interconnection.

It features 24 Gigabit RJ45 data ports plus 4 dedicated 10G SFP+ fiber uplink slots, offering 24 copper access interfaces + 4×10G high-speed uplink ports for scalable fiber backbone deployment. Powered by an upgraded high-performance ARM processor with 512MB DRAM and 256MB flash memory, it delivers 128 Gbps non-blocking switching capacity and 95.23 Mpps wire-speed forwarding rate for 64-byte frames, equipped with an enhanced 1.5MB shared dynamic packet buffer to eliminate congestion under bulk office file transfers, multi-stream IP surveillance backhaul and cross-site enterprise video conferences. Optimized variable-speed multi-fan thermal cooling ensures stable 24/7 continuous rack operation in office equipment rooms, retail server racks and campus wiring closets.
