Cisco CBS250-24T-4G Business 250 Series 24-Port Gigabit Non-PoE Smart Managed Switch, 4 Dedicated 1G SFP Uplink Slots, IPv4/IPv6 Static Layer 3 Routing, 1RU Rackmount Fanless Data Switch
2. Official Product Overview
The Cisco CBS250-24T-4G is a cost-effective non-PoE smart switch from the Cisco Business 250 Series, designed for medium-sized offices, branch headquarters, retail back offices, and multi-department wiring closets focused on data-only network connectivity. It delivers enterprise-grade switching performance, complete Layer 2 feature set, native IPv4/IPv6 Layer 3 static routing, multi-layer security, and simplified web management, without the extra cost of PoE power supply for environments deploying separately powered wireless APs, PCs, NAS, and POS terminals.
This model features 24×10/100/1000BASE-T copper RJ45 data ports plus 4 independent dedicated Gigabit SFP fiber uplink slots, delivering a total of 28 Gigabit Ethernet interfaces for flexible fiber long-distance uplink expansionCisco. Powered by an 800MHz ARM processor, 512MB DRAM and 256MB flash memory, it provides 56 Gbps switching capacity and 41.66 Mpps wire-speed forwarding rate for 64-byte frames, paired with 1.5MB shared packet buffer to support simultaneous file transfers, video conferencing, and surveillance data streams without congestion.
