Description

The Arista 7280R3 Series 7280SR3K-48YC8A is a 1RU fixed-configuration data centre switch router built for leaf, spine and internet-peering roles. It runs Arista EOS and suits 25/100G fabrics, edge routing that needs large route tables, and deep-buffer or low-latency workloads.

The front panel provides 48 SFP ports supporting 1G, 10G and 25G, plus 8 QSFP100 uplinks. Throughput is 2 Tbps with 4 GB of packet buffer and latency from 3.8 us. As a 7280R3K model it uses the FlexRoute engine to handle over 5M IPv4 routes. The A variant adds an eight-core x86 control-plane CPU with 64 GB of system memory and a 120 GB SSD. This SKU has front-to-rear airflow and ships with the FLX software licence, which sets it apart from other 7280R3 variants.

Power comes from hot-swappable PWR-511 supplies in a 1+1 redundant configuration, with a typical draw of 162 W and a maximum of 338 W. The 48 downlinks accept 1G, 10G and 25G SFP optics and DACs, and the 8 uplinks accept 40G and 100G QSFP optics, with exact support depending on the EOS version and transceiver chosen.
