Deliver high-power access switching where endpoint demands keep rising. The ExtremeSwitching 5520 48-port 802.3bt 90W model combines 48 Gigabit Ethernet PoE ports with support for up to 90 W per port, making it well suited for devices that exceed the limits of standard PoE and PoE+ designs. This switch is built for dense edge deployments that need more than basic connectivity. Stacking support helps simplify expansion and operational consistency across multiple switches, while the inclusion of 2 QSFP28 stacking ports gives the platform a stronger foundation for resilient interconnects. A single unpopulated VIM slot adds room for future interface flexibility, and MACsec capability supports secure transport in environments where traffic protection matters. With 3 fan modules and 2 unpopulated modular PSU slots, the chassis is designed for production use in demanding network closets and distribution areas. TAA compliance also makes it appropriate for procurement environments with sourcing requirements. For teams comparing access switches, this model stands out when endpoint power, operational resilience, and deployment flexibility all need to be addressed in one platform.
