Cisco CBS250-16T-E-2G Business 250 Series 16-Port Gigabit Non-PoE Smart Managed Switch, 2 Combo Gigabit SFP/RJ45 Uplink Ports, EU Power Version, Layer 3 Static Routing, Fanless 1RU Rackmount Data Switch
2. Official Product Overview
The Cisco CBS250-16T-E-2G belongs to the Cisco Business 250 Series cost-effective smart switches, designated as EU regional variant (-E suffix for European power standard). It targets small-to-medium businesses, branch offices, retail back offices and wiring closets without PoE-powered terminals, delivering enterprise-grade switching performance, full Layer 2 functions, native Layer 3 static routing, multi-layer security and user-friendly web management at budget-friendly cost. This non-PoE model is optimized for data-only networks including PCs, network printers, NAS storage, separate-powered wireless APs and POS terminals.
It equips 16×10/100/1000BASE-T copper RJ45 data ports plus 2 dual-purpose Gigabit combo uplink ports (each supports either RJ45 copper or SFP fiber transceiver), totaling 18 Gigabit Ethernet interfaces. Powered by an 800MHz ARM processor, 512MB DRAM and 256MB flash memory, it delivers 36 Gbps switching capacity and 26.78 Mpps wire-speed forwarding rate for 64-byte frames, supporting smooth concurrent file transfer, video conferencing and surveillance data streaming without congestion.
