This is an Arista Networks DCS-7800R3-48CQ-LC 7800R3 Series 48-Port 100GbE QSFP Wirespeed Line Card (P/N: DCS-7800R3-48CQ-LC). Designed for Arista's modular 7800R3 Series chassis, this high-performance line card delivers an exceptional 48 ports of 100 Gigabit Ethernet (100GbE), utilizing QSFP (Quad Small Form-factor Pluggable) transceivers. Operating at wirespeed, it ensures line-rate performance across all ports, making it ideal for the most demanding data center spine, core, and super-spine applications. The Front-to-Back Airflow design seamlessly integrates into modern hot-aisle/cold-aisle data center cooling strategies. As a critical component of the 7800R3 series, this line card provides massive scale, advanced Layer 2 and Layer 3 features, deep buffer capabilities, and robust programmability through Arista's EOS (Extensible Operating System). It's an indispensable building block for hyperscale cloud networks, enterprise data centers, and high-performance computing (HPC) environments requiring extreme bandwidth and consistent low latency.
