Model: CBS220-48T-4X-NA
from $783.95
The Cisco CBS220-48T-4X is a 48-port Gigabit managed network switch designed for robust network connectivity. It features 48 RJ45 Gigabit Ethernet ports, each supporting PoE+ (30W, 802.3at), alongside four 10 GbE SFP+ ports for high-speed uplinks. With a switching bandwidth of 176 Gb/s and a forwarding rate of 130.94 Mpps, this switch is well-suited for expanding and managing network infrastructure in small to medium-sized businesses, offering reliable performance and essential Layer 2 services.
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 $783.95.
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.
