Cisco CBS250-48T-4X Business 250 Series 48-Port Gigabit Non-PoE Smart Managed Switch, 4×10G SFP+ High-Speed Uplink Slots, Dual-Stack IPv4/IPv6 Layer 3 Static Routing, Fanless 1RU Rackmount High-Density 10G Aggregation Switch

2. Official Product Overview

The Cisco CBS250-48T-4X is a high-density non-PoE premium smart switch within the Cisco Business 250 Series, identified by the "-4X" suffix which stands for four 10-Gigabit SFP+ uplink ports. It is engineered for medium-to-large enterprise main distribution wiring closets, campus core networks, storage aggregation nodes and bandwidth-intensive office environments without PoE-powered endpoints. It delivers enterprise-grade wire-speed switching, complete Layer 2 feature toolkit, native dual-stack IPv4/IPv6 Layer 3 static routing, robust multi-layer security and intuitive unified web management, providing future-proof 10G high-bandwidth uplink aggregation for bulk file sharing, multi-stream 4K video, centralized storage access and cross-building interconnections.

This non-PoE model features 48×10/100/1000BASE-T copper RJ45 data ports plus 4 independent dedicated 10G SFP+ uplink slots, backward compatible with standard 1G SFP transceivers to support flexible migration between Gigabit and 10-Gigabit fiber/copper links. Powered by an 800MHz ARM CPU, 512MB DRAM and 256MB flash memory, it delivers 176 Gbps switching capacity and 130.94 Mpps wire-speed forwarding rate for 64-byte frames, equipped with a large 3MB shared dynamic packet buffer to eliminate congestion under heavy concurrent multi-user traffic loads.
