Powerful PoE+ Connectivity with Scalable Uplinks — Cisco CBS350‑24P‑4G‑CN Delivers Managed Gigabit Networking with Enhanced Security, QoS, and Flexible Fiber Integration.
Product Description
The Cisco CBS350‑24P‑4G‑CN is a managed Gigabit PoE+ Ethernet switch in the Cisco Business 350 Series, designed for modern business networks that require robust connectivity, secure management, and power delivery to edge devices. With 24 PoE+ ports delivering a 195 W PoE budget, it simplifies deployments of IP phones, wireless access points, and surveillance cameras without separate power supplies.
Model Type: Managed Gigabit Ethernet Switch (Layer 2/Basic Layer 3)
Category: Cisco Business 350 Series PoE+ Managed Switch
Key Features
• 24 × 10/100/1000 Mbps Gigabit PoE+ RJ‑45 Ports – All 24 downlink ports support IEEE 802.3at PoE+, delivering up to 195 W total PoE budget to power IP phones, wireless access points, cameras, and other PoE devices without external injectors.
• 4 × Gigabit SFP Uplink Ports – Dedicated uplinks for fiber connectivity to backbone switches, aggregation points, or long‑distance links, ensuring flexibility and scalability.
• High Switching Capacity & Performance – 56 Gbps switching capacity and up to 41.66 Mpps forwarding rate for smooth, efficient traffic handling across high‑density networks.
• Advanced Layer 2 & Basic Layer 3 – Support for VLANs, spanning tree (STP/RSTP/MSTP), link aggregation (LAG), and IPv4/IPv6 static routing with policy‑based routing (PBR) and RIP v2 capabilities.
• Robust Security & QoS – Features such as IEEE 802.1x, DHCP snooping, IP Source Guard, dynamic ARP inspection, ACLs, port security, and robust QoS for traffic prioritization.
• Comprehensive Management – Manage via Cisco Business Dashboard, web UI, CLI, SNMP v1/v2/v3, RMON, Telnet, SSH, and USB for configuration backup and image management.
• Energy‑Efficient & Fanless Design – Energy Efficient Ethernet (IEEE 802.3az) reduces power consumption while fanless operation makes this switch ideal for quiet office deployments.
