Managed L2 Gigabit Ethernet Switch Cisco CBS220-48P-4X-EU
The Cisco CBS220-48P-4X-EU is a managed L2 Gigabit Ethernet switch with 48 PoE-capable Gigabit RJ-45 ports and four 10G uplink ports. Designed for rack mounting, it offers a switching capacity of 176 Gbit/s and an 8192-entry MAC address table, supporting IEEE networking standards including 802.3af and 802.3at for powering devices over Ethernet. The white chassis and managed feature set make it suitable for small and medium business networks that require reliable connectivity and PoE support.
The CBS220-48P-4X-EU provides centralized management, PoE/PoE+ support on 48 ports, and 10G uplinks to integrate with higher-capacity cores. Its managed L2 feature set and compliance with common IEEE standards simplify interoperability and increase network uptime. Rack-mount design and a substantial switching capacity enable stable performance for converged data, voice, and video traffic.
Mount the Cisco CBS220-48P-4X-EU in a standard 19-inch rack using the included brackets. Connect uplink ports to your aggregation or core switch using 10G-capable cables and connect edge devices to the RJ-45 Gigabit ports. Configure VLANs, PoE settings, and L2 features through the switch's management interface or dashboard according to your network design. Verify firmware is up to date and monitor PoE power budgets when connecting multiple powered devices.
When deploying PoE devices, calculate the total PoE power draw to ensure the switch’s power budget meets your needs. Separate voice, data, and management VLANs for improved security and reliability, and use the 10G uplinks for aggregation to maintain sufficient bandwidth for converged traffic.
