Frequently Asked Questions
What makes the Extreme Networks 4120 ideal for Wi-Fi deployments?
The 24-port multi-gigabit PoE switch provides dedicated high-speed connectivity for multiple access points while delivering 90W PoE power to each port, eliminating the need for separate power infrastructure. Its 720 Gbps throughput ensures Wi-Fi traffic is never bottlenecked at the wired layer.
Can this multi-gigabit PoE switch support IoT and legacy devices simultaneously?
Yes. The 4120-24MW-4Y supports 10/100/1000/2.5G speeds on all 24 ports, allowing it to accommodate both modern multi-gigabit IoT sensors and traditional 1Gbps devices on the same switch without performance degradation.
How does ExtremeCloud IQ management simplify network operations?
ExtremeCloud IQ provides cloud-based centralized management, enabling IT teams to monitor, configure, and troubleshoot the switch remotely. This reduces on-site management overhead and provides real-time visibility into network health and device connectivity.
What are the uplink options for connecting to core network infrastructure?
The switch includes four 1/10/25Gb SFP28 ports and two 100Gb QSFP28 ports, providing flexible uplink choices. Organizations can use 25Gb SFP28 for cost-effective high-speed connections or 100Gb QSFP28 for maximum bandwidth to core switches and data center infrastructure.
