Cisco CBS350-8P-E-2G Full English Product Description

1. Short Sales Title (For Quotation & E-commerce Listing)

Cisco CBS350-8P-E-2G Business 350 Series 8-Port Gigabit PoE+ Fully Managed Switch, EU Regional Power Version, 67W Total PoE Budget, 2 Gigabit SFP/RJ45 Combo Uplinks, Dynamic IPv4/IPv6 Layer 3 Routing, True Stackable, Fanless 1RU Compact Rackmount PoE Switch

2. Official Product Overview

The Cisco CBS350-8P-E-2G is the EU regional variant of CBS350-8P-2G fully managed Layer 3 switch within Cisco Business 350 portfolio. The suffix "-E" stands for European standard power cord and EU compliance certifications, designed exclusively for European small offices, compact retail back offices, mini branch wiring closets and low-density PoE deployments.

Distinct from CBS250 smart switches, CBS350 delivers enterprise-grade full managed capabilities including dynamic Layer 3 routing, true stacking, comprehensive anti-spoofing security, sFlow monitoring and advanced multicast control. This PoE+ model integrates data transmission and PoE power supply in one compact 1RU unit, eliminating external power injectors for low-power Wi-Fi access points, entry-level VoIP phones and compact IP surveillance cameras.

It features 8 IEEE 802.3at PoE+ Gigabit RJ45 ports plus 2 dual-purpose Gigabit combo uplink ports (each supports RJ45 copper or SFP fiber transceiver), offering 10 total Gigabit Ethernet interfaces for flexible short copper or long-distance fiber uplink expansion. Equipped with internal power supply delivering a 67W total PoE budget, it supports standard low-power PoE endpoints without power overload risks.

Powered by high-performance ARM processor with 512MB DRAM and 256MB flash memory, it provides 20 Gbps non-blocking switching capacity and 14.88 Mpps wire-speed forwarding rate for 64-byte frames, paired with a 1.5MB shared packet buffer to avoid congestion under concurrent file sharing, video conferencing and surveillance streaming. Fanless passive cooling ensures silent deployment in offices, shops and classrooms.
