Description

The Arista DCS-7280PR3-24-F is a 1RU fixed data centre switch router from the 7280R3 Series, built around 24 x 400GbE OSFP ports and 9.6 Tbps of wire-speed throughput. A 16 GB deep packet buffer and Arista EOS make it well suited to large-scale data centre spine, internet peering and carrier edge deployments. This SKU ships with front-to-rear airflow and two AC power supplies.

Breakout cabling provides up to 96 x 100G, 192 x 50G or 192 x 25/10G ports for flexible port density. The FlexRoute engine carries full internet routing tables in hardware, while EVPN/VXLAN, MPLS and Segment Routing support modern overlay and WAN-edge designs. Hot-swappable redundant power supplies and fans, together with latency monitoring and precision timing, support demanding production environments.
