Support demanding edge deployments with the ExtremeSwitching 5420F. This fixed switch combines 8 high-power IEEE 802.3bt 90 W ports with 16 PoE+ ports, giving infrastructure teams the flexibility to connect everything from standard powered devices to higher-draw endpoints that exceed conventional PoE limits. It is a strong fit for modern access layers where endpoint mix and power requirements vary by zone, floor, or building. The platform also includes 4 unpopulated 10G SFP+ slots for uplink design flexibility and MACsec for secure traffic handling across the access edge. Stacking support helps simplify expansion and operational consistency across multiple switches, while the internal fixed PSU and fan design support a deployment model built for always-on network closets. Choose this model when you need more than basic PoE density. It is designed for environments where power headroom, secure uplinks, and access-layer scale justify a higher-spec switch. For teams standardizing on Extreme switching, the 5420F offers a practical way to support mixed-power endpoints without sacrificing uplink options or deployment control.
