CBS350-8S-E-2G Front Panel

2. Official Product Overview

The Cisco CBS350-8S-E-2G is the EU regional fiber-only fully managed Layer 3 switch within Cisco Business 350 portfolio, marked with suffix "-E" for European standard power cord and EU CE/RoHS compliance certifications. The "S" designation stands for dedicated Gigabit SFP fiber ports (no copper RJ45 access ports), engineered exclusively for European fiber aggregation scenarios, small optical wiring closets, remote building interconnection, fiber SAN access and CCTV fiber backhaul deployments without PoE endpoints.

Distinct from CBS250 smart switches and copper-based CBS350-8T/8P/8FP models, this all-fiber access variant delivers enterprise-class full managed capabilities including dynamic Layer 3 routing, true stacking, comprehensive anti-spoofing security, sFlow traffic monitoring and advanced multicast control. It provides pure fiber connectivity for long-distance inter-building links, fiber NAS storage and fiber-connected IP cameras, eliminating copper cabling distance limitations.

It features 8 dedicated Gigabit SFP fiber access slots plus 2 dual-purpose Gigabit combo uplink ports (each supports either RJ45 copper or SFP fiber transceiver), offering 10 total Gigabit Ethernet interfaces for flexible mixed fiber/copper uplink expansion. Powered by a high-performance 800MHz ARM processor with 512MB DRAM and 256MB flash memory, it delivers 20 Gbps non-blocking switching capacity and 14.88 Mpps wire-speed forwarding rate for 64-byte frames, paired with a 1.5MB shared dynamic packet buffer to eliminate congestion under concurrent fiber-transmitted surveillance streams, bulk file transfers and cross-site video conferences. Fanless passive cooling ensures zero-noise silent deployment in equipment rooms, office wiring closets and retail server rooms.
