Arista 7250QX Aggregation Leaf Switches - Refurbished, Used, and New
Arista 7250QX switches are 2RU, 64-port 40G QSFP+ aggregation and leaf switches for data center spine-leaf fabrics, running Arista EOS. Each QSFP+ port can run at 40G or break out to 4x 10G, so one DCS-7250QX-64 can serve as a dense 10G leaf, a 40G aggregation layer, or a mix of both. The switch comes in two airflow versions, front-to-back (-F) and back-to-front (-R), with matching power supplies and fan modules. NetworkTigers sells 7250QX switches, PWR-1100AC power supplies and FAN-7002 fan modules refurbished, used and new, and every unit is tested before it ships so it works when it arrives.

Which Arista 7250QX do I need?
Airflow decides everything on this platform. Pick -F if the QSFP+ ports face the cold aisle and exhaust goes out the power supply side, which is the usual data center layout, and -R if the ports face the hot aisle. The chassis, both power supplies and all fan modules must share the same direction, so a DCS-7250QX-64-F takes PWR-1100AC-F supplies and FAN-7002-F fans. Arista color-codes the handles, red for front-to-back and blue for back-to-front, so a mismatch is easy to spot. Power supplies and fans are sold separately so you can build the redundancy you want; a full switch runs two supplies. Then plan your ports: each QSFP+ port runs a 40G optic or DAC, or a breakout cable to four 10G links, so 64 ports can become up to 256x 10G leaf ports. Match the optics and cables to the reach between racks.
Frequently asked questions
Is the 7250QX the same as the 7260QX?
No. They share the same power supplies and fan modules, but the 7260QX is a different switch generation with a different port layout. Check the exact DCS part number on the listing against what your fabric already runs.
Can I use a 7250QX as a 10G top-of-rack switch?
Yes. With QSFP+ to 4x SFP+ breakout cables, each 40G port becomes four 10G server links, which makes the 7250QX a dense 10G leaf with 40G uplinks left over for the spine.
Does the switch ship with power supplies and fans installed?
Each listing states what is included. If you need a complete, redundant switch, tell us the airflow direction and we will put together the chassis, two supplies and a full set of fans.
