The Arista DCS-7280SR2A-48YC6-F is a fixed 1U data center switch with
48 × 25G SFP28 ports and 6 × 100G QSFP28 uplinks, built on Arista’s
EOS software for high-performance leaf and spine deployments. BrightStar Systems supplies
fully tested DCS-7280SR2A-48YC6-F switches backed by our
1-Year In-House Warranty
, helping you scale 25/100G networks at a fraction of new hardware cost.
Ideal for high-density 25G leaf, collapsed leaf/spine, and
border leaf roles, this platform supports advanced features like VXLAN, EVPN,
rich telemetry, and automation to simplify cloud-scale operations.
The DCS-7280SR2A-48YC6-F belongs to the Arista 7280R Series of fixed systems,
offering deep buffers, large routing scale, and wire-speed performance for modern leaf/spine,
IP fabric, and edge routing designs. With 48 × 25G access ports plus
6 × 100G uplinks, it delivers flexible connectivity for bare-metal servers,
hyperconverged infrastructure, and storage workloads.
Front-to-back (F) airflow, hot-swappable components, and field-proven EOS software make this
platform a reliable choice for production data centers requiring predictable latency, rich
automation APIs, and seamless integration with orchestration tools.

The DCS-7280SR2A-48YC6-F uses front-to-back (F) airflow, making it
a natural fit for data centers with cold aisles at the front of the rack and hot aisles at the rear.
If you operate a back-to-front (R) airflow environment, our team can help you select the correct airflow
variant or alternative 7280R models to match your cooling design.
The DCS-7280SR2A-48YC6-F supports a wide range of 25G and 100G optics and DACs, allowing you to
mix short-reach, long-reach, and breakout connections in the same chassis. Commonly used options include:
BrightStar Systems can also help you bundle compatible optics and DACs with your switch
purchase to simplify deployment and reduce overall project cost.
