1. Short Sales Title (For Quotation & E-commerce Listing)
Cisco CBS350-16P-2G Business 350 Series 16-Port Gigabit PoE+ Fully Managed Layer 3 Switch, Global Standard Version, 120W Mid PoE Power Budget, 2 Gigabit SFP/RJ45 Combo Uplinks, Dual-Stack IPv4/IPv6 Dynamic Routing, True Stackable, Fanless 1RU Rackmount Mid-Density PoE Access Switch
2. Official Product Overview
The Cisco CBS350-16P-2G is a global mid-density PoE+ fully managed Layer 3 switch from the Cisco Business 350 product line, designed for small-to-medium enterprise office access layers, retail store unified voice-video networks, campus classroom wiring closets and mid-scale low-to-medium power IP surveillance deployments.
Compared with entry-level CBS250 smart switches, CBS350 delivers complete enterprise-grade managed capabilities, including dynamic Layer 3 routing, true stacking, comprehensive anti-spoofing security suite, sFlow traffic analytics and full-featured multicast control. This PoE model integrates data transmission and PoE power supply in one compact 1RU silent unit, eliminating external power injectors for standard Wi-Fi 6 APs, entry-level PTZ IP cameras and video VoIP phones.
It features 16 IEEE 802.3at PoE+ Gigabit RJ45 access ports plus 2 dual-purpose Gigabit combo uplink ports (each supports RJ45 copper or SFP fiber transceiver), offering 18 total Gigabit Ethernet interfaces for flexible short copper or long-distance fiber uplink expansion. Equipped with an internal power supply delivering a 120W total PoE budget, each port supports up to 30W PoE+ output for mainstream low/medium-power PoE endpoints.
Powered by a high-performance ARM processor with 512MB DRAM and 256MB flash memory, it provides 36 Gbps non-blocking switching capacity and 26.78 Mpps wire-speed forwarding rate for 64-byte frames, paired with a 1.5MB shared dynamic packet buffer to eliminate congestion under concurrent bulk file transfers, multi-stream 4K surveillance and multi-user video conferences. Fanless passive cooling enables zero-noise deployment in offices, retail shops and educational environments.
