Description

The Arista 7280R3A is a 1RU fixed data centre switch router built for leaf and spine designs, secure internet peering, carrier edge VPN services and IP/MPLS transport. It runs Arista EOS and pairs wire-speed forwarding with a 4 GB deep packet buffer, which suits routing roles where large route tables and bursty traffic are common.

This 7280CR3A-32S variant provides 30 x QSFP100/200 ports plus 2 x QSFP200/QSFP-DD ports, with breakout support for up to 2 x 400G, 18 x 200G, 36 x 100G, 56 x 50G or 56 x 25/10G interfaces. Throughput is 3.6 Tbps (7.2 Tbps full duplex) at 1.35 Bpps, with latency from 3.8 us. It has front-to-rear airflow, 2 x hot-swap AC power supplies in a 1+1 configuration and 3 x hot-swap fans in an N+1 arrangement. Typical power draw is 302 W, with a maximum of 481 W excluding transceivers. The -FLX suffix indicates the bundle includes an Arista FLX-class EOS software licence.

The ports accept QSFP100 and QSFP200 optics and cables, and the QSFP-DD ports support 400G. The switch requires EOS 4.32.1 or later and is managed with CloudVision.
