Arista 750X Series Modular Campus Switches

The Arista 750X Series consists of two modular campus switch chassis, the CCS-758-X3 (8-slot, 10RU) and the CCS-755-X3 (5-slot, 7RU), delivering up to 1.6 Tbps and 1.15 Tbps of switching capacity respectively. Each chassis accepts interchangeable line cards across five form factors, spanning 1G, 2.5G, 5G, and 10G copper downlinks with PoE power levels of 30W, 60W, and 90W per port. The CCS-758-X3 accommodates up to 384 ports and the CCS-755-X3 up to 240 ports, giving network architects a single modular platform that scales from small-to-medium core deployments to high-density enterprise distributions.

Each chassis houses two supervisor modules in a 1+1 Active/Standby arrangement with sub-second stateful failover, eliminating single points of failure at the campus core. Supervisors carry a Quad-Core x86 processor, 16 GB of RAM, 120 GB of SSD storage, and either 2× 100G QSFP or 4× 25G SFP uplink ports for spine or aggregation connectivity. Hot-swap power supplies (ten for the CCS-758-X3 and six for the CCS-755-X3), combined with N+1 hot-swap cooling fans, ensure that no maintenance operation requires a planned downtime window. Arista EOS runs as a common binary across the platform, providing a consistent operational model whether managing a single 755 chassis or a large multi-site 750X estate.
