Sustain critical edge connectivity with the Extreme Networks 5320-16P-4XE, a 16-port PoE+ switch built for access-layer deployments that need power, uplink flexibility, and security in one chassis. It delivers 16 10/100/1000Base-T PoE+ ports for endpoint power, plus 4 1 GbE SFP ports that are upgradeable to 10G SFP+ for higher-capacity uplinks when the network grows. MACsec capability helps protect traffic across the wired edge, making this model a strong fit for environments where access security is part of the design standard. The fixed AC power supply simplifies deployment, while the fan-based design supports sustained operation in business and campus closets. Compared with basic PoE switches, this model gives infrastructure teams more headroom at the uplink layer and a stronger security posture without moving to a larger chassis. For organizations standardizing on secure, managed access switching, the 5320-16P-4XE is built to support the devices that cannot go dark.
