## Long description

The Cisco Business 350 Series Switches are a family of affordable managed Ethernet switches designed for small offices. The CBS350-48T-4G model provides 48 Gigabit Ethernet ports and modular uplink options, combining manageability, security features, and compact design to form a reliable building block for small office networks. The series supports IPv4 and IPv6, offers advanced Layer 3 static routing, and includes Power over Ethernet (PoE/PoE+) options on select models to power IP phones, wireless access points, and surveillance devices over a single cable.
Advantages
The CBS350-48T-4G delivers a balance of affordability and functionality with managed L2/L3 features, advanced security management, and a straightforward dashboard for simplified setup and configuration. It supports automated voice deployment using LLDP-MED and Cisco discovery protocols, offers IPv6 readiness with USGv6/IPv6 Gold certification, and provides compact form factor options that suit wiring closets and open office environments.
Suitable for
Small office networks requiring 48 Gigabit Ethernet ports
Deployments needing managed switching with L2 and static L3 routing
Environments using IP telephony, wireless access points, or IP surveillance (PoE/PoE+ models)
Networks transitioning to IPv6 while maintaining IPv4 support
Key specifications
Model: CBS350-48T-4G (Managed L2/L3 switch)
Ports: 48 × Gigabit Ethernet (10/100/1000) RJ-45
Uplinks: 10G-capable uplink ports
MAC address table: 16,000 entries
Standards: IEEE 802.1w, 802.3ad, 802.3z, 802.3ab, 802.3u, 802.3, 802.1s, 802.1D
PoE/PoE+ support: available on PoE models (802.3af/802.3at)

How to use
Install the switch in a standard rack or on a flat surface according to the installation guide. Connect Ethernet devices to the RJ-45 ports and configure the switch via the intuitive web dashboard, CLI, or management tools. For voice deployments, enable LLDP-MED and the Cisco voice discovery features to automatically assign voice VLAN and QoS settings to connected IP phones. Configure static Layer 3 routes to segment traffic between VLANs and offload internal routing from the network router.
Usage recommendations
Place the switch in a temperature-controlled environment and ensure adequate ventilation. For PoE deployments, verify the selected model’s total PoE budget before connecting multiple powered devices. Keep firmware updated and use VLANs and QoS to prioritise voice and critical traffic.
