Switch Gerido Cisco CBS220-48T-4G

The Cisco CBS220-48T-4G is a managed Layer 2 Gigabit Ethernet switch with 48 Gigabit RJ-45 ports and four SFP+ / uplink ports, designed for small business networks that require predictable performance, security, and centralized management. Rack-mountable at 1U and offering a switching capacity of 104 Gbit/s with an 8192-entry MAC address table, this switch supports common enterprise networking standards and Power over Ethernet options for converged data, voice, and wireless deployments.

Advantages

The CBS220-48T-4G delivers straightforward management via the Cisco Business Dashboard and mobile app, enabling simplified deployment, monitoring, and lifecycle operations. It offers PoE/PoE+ compatibility for powering access points and IP devices, industry-standard protocols for interoperability, and a compact 1U rack design that fits small office environments while providing the performance and security features expected in business-class networks.

Suitable for

• Small office networks with limited IT staff
• Converged deployments carrying data, voice (IP telephony), and video
• Wireless access point backhaul with PoE/PoE+ power requirements
• Environments requiring VLANs, link aggregation, and basic layer‑2 security (802.1x)

How to use

Install the CBS220-48T-4G in a standard 19-inch rack using the included mounting brackets and connect power. Use the Cisco Business Dashboard or mobile app to perform initial setup, create VLANs, configure QoS, enable 802.1x authentication, and set up PoE priorities for connected devices. Connect switches to uplinks via the SFP/SFP+ ports for aggregation or to upstream routers. Monitor port status, bandwidth usage, and device health through the dashboard for ongoing management.

Recommendations

For stable converged networks, plan VLAN segmentation for voice, video, and data, enable QoS for delay-sensitive traffic, and allocate PoE/PoE+ power budgets before deploying APs, IP phones, or cameras. Regularly back up configurations via the Cisco Business Dashboard and keep firmware updated to maintain security and compatibility.
