Frequently Asked Questions
What is a 48-port Gigabit Ethernet switch used for?
A 48-port Gigabit Ethernet switch like the 5420M-48T-4YE provides centralized connectivity for enterprise networks, connecting multiple devices such as servers, workstations, and access points. The combination of 48 standard ports and 4 high-speed SFP28 uplinks makes it ideal for edge deployments requiring both broad device connectivity and high-capacity backbone links.
What is MACsec and why does it matter?
MACsec (Media Access Control Security) is a Layer 2 security protocol that encrypts and authenticates data at the link layer. The 5420M-48T-4YE's MACsec capability protects against man-in-the-middle attacks and unauthorized access, making it essential for organizations with strict security compliance requirements in campus and data center environments.
Can the Extreme Networks 5420M-48T-4YE be stacked with other switches?
Yes, the 5420M-48T-4YE features 2 x SFP-DD stacking ports that enable seamless multi-switch stacking. This allows organizations to create larger logical switch fabrics, simplifying management and improving redundancy across enterprise network deployments.
What uplink options does this switch provide?
The switch includes 4 x 1/10/25Gb SFP28 uplink ports that support flexible bandwidth scaling. These ports can operate at 1Gb, 10Gb, or 25Gb speeds, providing high-speed connectivity to core network infrastructure, storage systems, or upstream aggregation switches.
