DCS-7280CR3K-32P4-R is a fixed-configuration 1RU Arista 7280R3K switch/router designed for high-throughput data center and service provider environments. This model provides a mixed high-speed interface profile and is built for deployments that require rear-to-front airflow (-R).
As part of the 7280R3K platform, this system is optimized for large routing tables and is commonly deployed at the fabric edge and aggregation layers where scale, throughput, and predictable forwarding performance are required.
The DCS-7280CR3K-32P4-R is typically deployed in environments that require both high-speed connectivity and increased routing scale. Common use cases include large-scale data center fabrics, service provider aggregation, and routing-intensive edge deployments where airflow direction must align with rack design.
If your rack airflow direction requires the opposite cooling orientation, see the front-to-rear airflow variant:
