The Arista DCS-7504N-CH is an empty 7500R modular chassis designed to accept up to two SUP-2 supervisor modules, four line-card slots, and six fabric slots, enabling scalable, high-density data-center interconnects. As a chassis-only unit, AC or DC power supplies are ordered separately, and the fabric slots require dedicated 7500R Fabric modules to provide inter-switch connectivity. This chassis sits within Arista's 7500R family and supports a range of line cards and fabric modules, delivering wirespeed port speeds from 1G to 100G as the installed modules allow.
