The Cisco CBS220-48P-4G is a managed network switch designed to provide reliable connectivity and power for your business network. This Layer 2 switch features 48 Gigabit Ethernet ports with PoE+ (802.3at) support, offering a substantial 382W power budget to power devices like IP phones and wireless access points. Four additional SFP Gigabit Ethernet ports provide flexible uplink options. With a switching bandwidth of 104 Gb/s and a forwarding rate of 74.38 Mpps, it efficiently handles network traffic, while security features like DoS attack prevention and RADIUS authentication help protect your network. Its fan-based cooling system operates at a quiet 34.8 dB, making it suitable for various office environments.
For home use, a simple unmanaged Gigabit switch is all you need to expand your router's ports. Buy a managed switch or a switch with PoE only if you are running security cameras, access points, or complex VLAN setups. Available from $777.99.
Basic unmanaged network switches use negligible power and have zero maintenance costs. PoE (Power over Ethernet) and large managed switches use more electricity but are still relatively cheap to run.
Common Failure Modes
Switches are solid-state devices with high reliability. When they fail, it is usually due to lightning strikes/power surges blowing individual ports or the internal power supply dying.
