The Extreme Networks 7520 Series Campus Core Switch (part number 17721) is a modular campus core switch in a 3U rack form factor. It supports 25G and 100G port speeds and uses a modular switching architecture, giving network teams a core platform for aggregating traffic across a campus network.
Protocol support includes Ethernet, IPv4, IPv6 and MPLS, and the switch is managed through ExtremeCloud IQ. For resilience, it supports dual power supplies and dual fan trays. Maximum power consumption is rated at 4000 W, and the specified operating temperature range is 0–40°C.
This switch is suited to the core layer of campus and enterprise networks, where high-speed uplinks, redundant hardware components and centralised management are required in a rack-mounted data or network room environment.
