Extreme Networks ExtremeSwitching 5420M 24-Port PoE++ Switch

Overview

The Extreme Networks 5420M-24W-4YE is a 24-port Gigabit Ethernet switch designed to deliver robust PoE++ power and advanced Layer 3 control for edge and aggregation network layers. It supports a total power budget of 1440 W, allowing each copper port to provide up to 60 W, which is ideal for powering Wi-Fi access points, PTZ security cameras, VoIP phones, and digital signage without the need for additional power injectors. With flexible uplink options including four SFP28 ports supporting 1, 10, or 25 Gigabit speeds and two SFP-DD ports for stacking, this switch offers scalable performance for growing network environments.

Key features

• Power over Ethernet Plus Plus (PoE++) on all 24 copper ports to support high-power devices directly from the switch
• Flexible uplink speeds with four SFP28 ports that accept 1, 10, or 25 Gigabit optics for diverse network demands
• Stacking capability with two SFP-DD ports allowing up to eight switches to be combined, providing a high aggregate bandwidth of 328 Gbps
• Advanced Layer 3 features enable routing at the edge, supporting larger VLAN counts and efficient traffic segmentation
• Security enhanced by MACsec encryption to protect sensitive data on links between access points and switches
• Management options include a familiar command-line interface (CLI) and remote tools for streamlined network administration
• Rack-mountable design fits standard 19-inch racks, simplifying installation in existing network cabinets or server rooms
