1. Short Sales Title (For Quotation & E-commerce Listing)

Cisco CBS350-24XT Business 350 Series 24-Port 10GBase-T Non-PoE Fully Managed Layer 3 Switch, Global Standard Version, 4×10G SFP+/RJ45 Combo Uplink Interfaces, Dual-Stack IPv4/IPv6 Dynamic Routing, True Stackable, 1RU Rackmount Pure 10G High-Density Core Aggregation Switch

2. Official Product Overview

The Cisco CBS350-24XT is a full 10-Gigabit copper non-PoE fully managed enterprise Layer 3 switch in the Cisco Business 350 product lineup. The suffix XT stands for 24×10GBase-T copper access ports (all 10G RJ45, no Gigabit-only ports), with four shared 10G SFP+/RJ45 combo uplink interfaces (all 10G speed, no 1G-only 4G SFP uplinks). Designed for high-bandwidth enterprise core aggregation, multi-building campus fiber backbone, high-performance editing workstations, centralized NAS storage and 10G fiber surveillance backhaul environments without PoE requirements.

Compared with entry-level CBS250 smart switches, CBS350 delivers complete enterprise-grade managed capabilities: dynamic RIPv2 Layer 3 routing, true single-IP stacking (up to 4 switches), comprehensive anti-spoofing security suite, sFlow traffic analytics and full-featured multicast control. This all-10G copper switch eliminates Gigabit bottlenecks for bandwidth-intensive workloads, supporting 10G copper desktop/storage devices and redundant long-distance 10G fiber interconnection via combo SFP+ uplinks.

It features 24×10GBase-T RJ45 non-PoE access ports plus 4 dual-purpose 10G SFP+/RJ45 combo uplink ports, delivering 28 total 10G wire-speed interfaces for fully non-blocking high-speed internal network and cross-building backbone deployment. Powered by an 800MHz ARM processor with 512MB DRAM and 256MB flash memory, it provides 480 Gbps non-blocking switching capacity and 357.14 Mpps wire-speed forwarding rate for 64-byte frames, paired with a large 3MB shared dynamic packet buffer to eliminate congestion under 10G 4K video editing, bulk multi-TB storage file transfers and mass fiber surveillance streaming. Optimized multi-fan cooling ensures stable 24/7 rack operation in core data rooms, media production studios and campus equipment racks.
