2. Official Product Overview

The Cisco CBS250-24T-4X is a premium non-PoE smart switch from Cisco Business 250 Series, distinguished by four 10-Gigabit SFP+ uplink ports (the "-4X" suffix stands for 4×10G SFP+), designed for medium enterprises, branch core wiring closets, data storage networks and bandwidth-heavy office environments without PoE endpoints. It delivers enterprise-grade wire-speed switching, complete Layer 2 feature toolkit, native dual-stack IPv4/IPv6 Layer 3 static routing, comprehensive multi-layer security and intuitive web management, providing future-proof 10G uplink expansion for high-throughput data transmission such as large file sharing, 4K video streaming and multi-user cloud access.

This non-PoE model integrates 24×10/100/1000BASE-T copper RJ45 data ports plus 4 independent dedicated 10G SFP+ uplink slots, supporting both 10Gbps and 1Gbps transceivers for flexible migration between Gigabit and 10-Gigabit fiber/copper uplinks. Powered by an 800MHz ARM processor, 512MB DRAM and 256MB flash storage, it delivers 68 Gbps switching capacity and 50.95 Mpps wire-speed forwarding rate for 64-byte frames, equipped with 1.5MB shared dynamic packet buffer to eliminate congestion under heavy concurrent data loadsCisco.
