Cisco CBS350-48FP-4X Ethernet Switch — 48-Port PoE+ Smart Managed Switch for Small Offices

The Cisco Business 350 Series CBS350-48FP-4X Ethernet Switch is designed to deliver reliable, secure, and scalable connectivity for small offices and branch environments. Built to simplify deployment without sacrificing enterprise-grade features, this smart managed switch combines robust Layer 2+ capabilities with a rich set of security and management tools. With 48 PoE+ capable ports and four high-speed uplinks, the CBS350-48FP-4X is ideal for powering IP phones, cameras, wireless access points, and other network devices while keeping performance predictable for critical business applications.

• 48-Port PoE+ connectivity with flexible power delivery — Power a fleet of IP phones, IP cameras, and wireless access points directly from the switch, reducing clutter and simplifying cabling in small office deployments. The CBS350-48FP-4X provides PoE+ on multiple ports to support energy-hungry devices while maintaining stable performance for data traffic.
• High-speed uplinks for scalable growth — Four 10-Gigabit uplinks (SFP+ options) give you ample headroom for uplink aggregation, server access, and rapid data transfers between switches or to a merger with a larger network. This setup supports future-proofing as your office expands.
• Smart Managed features for secure, efficient networks — This Cisco switch pairs an intuitive Web UI with CLI access and Smart Install capabilities, enabling quick deployment, centralized management, and scalable policy enforcement. It includes advanced Layer 2+ features such as VLANs, QoS, link aggregation, and robust security controls to protect your network edges.
• Security‑first design with flexible access controls — Benefit from comprehensive security options including 802.1X authentication, ACLs, DHCP snooping, storm control, and port security. These features help safeguard sensitive data, prevent rogue devices from joining the network, and enforce segment isolation for guest access or department networks.
• Reliability and efficiency built for office environments — Engineered with a sturdy build and energy-conscious operation, the CBS350-48FP-4X minimizes noise and power usage while delivering consistent performance for everyday business workloads. The switch supports features like QoS and traffic prioritization to ensure critical applications—voice, video, and conference collaboration—receive the bandwidth they require.

How to install Cisco CBS350-48FP-4X

• Unbox and inspect the switch for any shipping damage, then connect the unit to a power source and place it in your intended network rack or cabinet.
• Mount the switch securely in a rack or place it on a stable surface, ensuring adequate ventilation to maintain optimal operating temperatures.
• Connect the network backbone to the four 10G SFP+ uplink ports using appropriate fiber or copper modules, depending on your topology and ISP/provider requirements.
• Power on the device and access the management interface using the default discovery method (the switch can be located via its local management interface or through Cisco FindIT for easier onboarding).
• Run the initial setup wizard to configure basic settings: IP address for management, VLAN segmentation (including a dedicated management VLAN), PoE settings, and basic security (802.1X, ACLs). Enable QoS policies to prioritize voice and video traffic and configure link aggregation (LACP) if you plan to connect multiple switches for redundancy or performance.

Frequently asked questions

• What is the Cisco CBS350-48FP-4X best for? — It is ideal for small offices and branches that need a secure, scalable, and affordable managed switch with PoE capability and high-speed uplinks to support IP phones, cameras, wireless access points, and server connections.
