Frequently Asked Questions
What is a multi-gigabit PoE switch and why do I need one?
A multi-gigabit PoE switch delivers data and power over a single cable to networked devices. The 4120-48MW-4Y's 2.5G ports support modern high-bandwidth devices like 4K IP cameras, Wi-Fi 6 access points, and IoT sensors while eliminating separate power infrastructure. This reduces installation costs and simplifies network design.
Is the Extreme Networks 4120-48MW-4Y suitable for government procurement?
Yes. The 4120-48MW-4Y is TAA compliant, meeting Trade Agreements Act requirements for government and regulated sector purchases. This certification ensures the switch meets domestic content and sourcing standards required by federal agencies and institutions.
How does cloud management simplify network operations?
The cloud-managed architecture enables centralized policy deployment, real-time monitoring, and remote troubleshooting across multiple switches from a single dashboard. This reduces on-site management overhead and accelerates network provisioning for distributed deployments.
Can I stack multiple 4120-48MW-4Y switches together?
Yes. The 4120-48MW-4Y supports stackable configurations with up to 6 units connected via the 2x 100G QSFP28 stack ports. Stacking simplifies management by treating multiple switches as a single logical entity while maintaining individual port density.
