Frequently Asked Questions
What is a managed switch and why do I need one?
A managed switch provides advanced network control, monitoring, and security features compared to unmanaged alternatives. The Extreme Networks 5520-48T enables VLAN configuration, quality of service (QoS), port mirroring, and MACsec encryption—essential for enterprise networks requiring security, performance optimization, and detailed traffic visibility.
What does MACsec capable mean?
MACsec (Media Access Control Security) is a Layer 2 security protocol that encrypts and authenticates Ethernet frames. MACsec capable ports on the 5520-48T allow you to implement encrypted point-to-point links, protecting sensitive data from eavesdropping and tampering within your local network.
How do QSFP28 stacking ports work?
The 2 QSFP28 stacking ports enable you to connect multiple 5520 switches together, creating a single logical unit. This stackable switch architecture simplifies management, increases port density, and provides redundancy—ideal for growing networks without replacing existing infrastructure.
Is the 5520-48T suitable for government procurement?
Yes. The TAA (Trade Agreements Act) compliance designation makes this TAA compliant switch eligible for U.S. federal government and regulated sector purchases, meeting procurement requirements for organizations with government contracts.
