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

Cisco CBS350-24FP-4G Business 350 Series 24-Port Full PoE+ Gigabit Fully Managed Layer 3 Switch, Global Standard Version, 370W Full PoE Power Budget, 4 Dedicated Gigabit SFP Uplink Slots, Dual-Stack IPv4/IPv6 Dynamic Routing, True Stackable, Fanless 1RU Rackmount High-Density Full PoE Aggregation Switch

2. Official Product Overview

The Cisco CBS350-24FP-4G is the flagship high-power full PoE+ 24-port fully managed Layer 3 switch within Cisco Business 350 global portfolio. The "FP" suffix represents Full PoE+, equipped with a robust 370W total PoE power pool, far exceeding the 195W partial PoE CBS350-24P-4G variant. It supports all 24 copper ports to deliver full 30W IEEE 802.3at PoE+ output simultaneously without power budget restrictions, designed for medium-to-large high-density PoE deployments including campus-wide Wi-Fi 6/6E coverage, mall full PTZ surveillance systems, enterprise unified video VoIP networks and classroom thin client power environments worldwide.

Distinct from entry-level CBS250 smart switches, the CBS350 platform delivers complete enterprise-grade managed capabilities: dynamic Layer 3 routing, true stacking, comprehensive anti-spoofing security suite, sFlow traffic analytics and advanced multicast control. This model integrates data transmission and high-output PoE power supply in one silent 1RU rack unit, eliminating external power injectors for power-hungry PTZ 4K IP cameras, high-output Wi-Fi APs, multi-line video IP phones and IoT monitoring terminals.

It features 24 IEEE 802.3at PoE+ Gigabit RJ45 access ports plus 4 independent dedicated Gigabit SFP fiber uplink slots (4G = 4×1G SFP, not 10G SFP+) for long-distance cross-building or cross-branch fiber interconnection, offering 28 total Gigabit Ethernet interfaces. Powered by a high-performance ARM processor with 512MB DRAM and 256MB flash memory, it delivers 56 Gbps non-blocking switching capacity and 41.66 Mpps wire-speed forwarding rate for 64-byte frames, paired with a large 1.5MB shared dynamic packet buffer to eliminate congestion under concurrent multi-camera 4K streaming, bulk file transfers and multi-user video conferences. Fanless passive cooling ensures zero-noise silent deployment in offices, retail malls and educational facilities.
