Arista Networks, Inc. DCS-7500R-36CQ-LC Line Card

Arista DCS-7500R-36CQ-LC is a 36-port line card for Arista’s 7500R modular data-center switches, delivering 36 independent 100GbE QSFP100 ports for high-density uplinks in large-scale deployments. It supports mixed-speed environments, enabling 10G/40G/100G connectivity within a single 7500R chassis and delivers wirespeed forwarding across all ports. As part of the 7500R family, the card is designed to plug into the chassis to scale core and aggregation fabrics in data centers that require substantial port density and high throughput. This model is documented by Arista as a 7500R Series 36-port, 100GbE QSFP100 wirespeed line card, and Arista’s end-of-sale advisory notes a replacement pathway with the DCS-7500R2-36CQ-LC.
