Support the most power-hungry edge devices without adding external injectors or separate power infrastructure. The Extreme 5520-48W provides 48 Gigabit Ethernet ports with 802.3bt PoE delivering up to 90 W per port, making it suitable for advanced wireless access points, PTZ cameras, thin clients, and other high-draw endpoints. For organizations standardizing on dense access switching, that level of per-port power changes what can be deployed at the edge. This switch is built for enterprise environments where security and expansion matter. MACsec capability helps protect traffic in transit, while the platform includes 2 stacking/QSFP28 positions, an unpopulated VIM slot, and 3 fan modules. Two unpopulated modular PSU slots give teams a path to higher availability and serviceability without replacing the chassis. Choose this model when you need more than basic PoE. The 5520-48W is designed for access layers that carry both power and performance requirements, especially where future expansion, secure connectivity, and operational resilience justify a higher-capacity switch platform.
