Arista Cognitive Campus CCS-720D Series Switches

The Arista CCS-720D Series encompasses seven campus access switch models across 1G and 2.5G downlink configurations in 24- and 48-port form factors. PoE variants (the 720DP models) deliver 30W per port at 1G (802.3at) or 60W per port at 2.5G (802.3bt), covering the power requirements of standard IP phones, Wi-Fi 6 access points, and higher-wattage Wi-Fi 7 APs from a single access switch tier. The 720DT and 720DF non-PoE models provide data-only access switching for environments where endpoint power is not a requirement, with the 720DF-48Y offering 48 ports of 1G SFP fibre access combined with 4× 25G uplinks for fibre-to-the-desk or distribution aggregation scenarios.

All 720D models are built around dual 1+1 redundant AC power supplies and N+1 hot-swap fans, ensuring that a single component failure does not disrupt access switching in floors or wings of a building where a redundant switch is not cost-justified at the access tier. Four 10G SFP uplinks (or four 25G SFP uplinks on the 720DF-48Y) connect to the distribution or aggregation layer over standard structured cabling or fibre. Arista EOS runs as a common software binary across the 720D, 720XP, and 750X families, meaning that a network administrator deploying 720D switches at access and 750X modular switches at campus core manages both tiers with the same CLI, API surface, and telemetry pipeline.
