Cisco CBS350-8P-2G Full English Product Description
1. Short Sales Title (For Quotation & E-commerce Listing)
Cisco CBS350-8P-2G Business 350 Series 8-Port Gigabit PoE+ Fully Managed Switch, 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-2G is an enterprise-class fully managed PoE switch within the Cisco Business 350 Series, designed for small offices, compact branch wiring closets, retail back offices and small surveillance deployments that require integrated data transmission and PoE power delivery. Unlike CBS250 smart switches, the CBS350 platform delivers robust full Layer 3 dynamic routing, true stacking, comprehensive anti-spoofing security, advanced multicast control and professional traffic management, ideal for unified voice, video, data and wireless SMB networks.
This mid-low power PoE model is equipped with 8 IEEE 802.3at PoE+ Gigabit RJ45 ports plus 2 dual-purpose Gigabit combo uplink ports (each supports either RJ45 copper or SFP fiber transceiver), delivering a total of 10 Gigabit Ethernet interfaces for flexible short-distance copper or long-distance fiber uplink expansion. It features an internal power supply providing a 67W total PoE budget, supporting standard PoE endpoints such as low-power Wi-Fi access points, entry-level IP phones and compact IP cameras without external power injectors.
Powered by a high-performance 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 file transfers, video conferencing and surveillance streaming. The fanless passive cooling design enables silent deployment in offices, shops and classrooms without acoustic noise.
