Enterprise‑Ready PoE+ Connectivity & Fiber Uplinks — Cisco CBS350‑48FP‑4G‑CN Delivers High‑Density Power and Performance with Advanced Security and Layer 3 Functionality
Product Description
The Cisco CBS350‑48FP‑4G‑CN is a high‑density managed Gigabit Ethernet switch from the Cisco Business 350 Series, designed for business and enterprise environments that demand reliable PoE power delivery and advanced network control. With 48 PoE+ capable Gigabit ports and a generous 740 W PoE budget, this switch can power numerous networked devices — from IP cameras and phones to wireless access points — while simplifying deployment and reducing cabling complexity.
Model Type: Managed Gigabit Ethernet Switch (Layer 2/Basic Layer 3)
Category: Cisco Business 350 Series High‑Density PoE+ Managed Switch
Key Features
• 48 × 10/100/1000 Mbps Gigabit PoE+ Ports – All 48 access ports support IEEE 802.3af/at PoE+, providing up to 740 W total PoE power budget to power devices like VoIP phones, wireless access points, IP cameras, and more without external injectors.
• 4 × 1 Gbps SFP Uplink Ports – Dedicated fiber uplinks for backbone connections, aggregation, or uplinking to core switches with flexible media options.
• High Switching Capacity & Performance – 104 Gbps non‑blocking switching capacity with ~77.38 Mpps forwarding performance, delivering smooth traffic handling for business networks.
• Advanced Layer 2 & Basic Layer 3 Features – Supports VLANs, link aggregation (LAG), STP/RSTP/MSTP, static IPv4/IPv6 routing, RIP v2, PBR, and CIDR for flexible traffic segmentation and inter‑VLAN routing.
• Robust Security & QoS – Includes ACLs, IEEE 802.1X authentication, DHCP snooping, IP/MAC port security, dynamic ARP inspection, storm control, and QoS with traffic prioritization for voice/video/data.
• Energy‑Efficient & Managed Operation – Supports IEEE 802.3az Energy Efficient Ethernet to reduce power consumption; management via Cisco Business Dashboard, web GUI, CLI, SNMP, RMON, Telnet, SSH, and RESTful options.
• Rack‑Mountable Design – A 1U rack form factor with internal power supply makes this switch ideal for wiring closets, server rooms, and structured cabling racks in business environments.
