Arista 7050Q 40G Leaf Switches - Refurbished, Used, and New
Arista 7050Q and 7050QX switches are 1U 40G leaf and spine switches running Arista EOS, built around QSFP+ ports that run at 40G or break out to 4x 10G. The 7050Q-16 pairs 16 QSFP+ ports with 8 SFP+ ports; the 7050QX-32 and 7050QX-32S carry 32 QSFP+ ports, with the 32S adding 4 SFP+ ports; the 7050QX2-32S is the later revision of the 32S. Each model ships in front-to-back (-F) or back-to-front (-R) airflow. NetworkTigers sells 7050Q and 7050QX switches and their rack kits refurbished, used and new. Every unit is tested before it ships so it works when it arrives.

Which 7050Q do I need?
Count the 40G links you need today and the 10G links you want to break out. The 7050QX-32 and 32S give 32 QSFP+ ports; with breakout cables each becomes 4x 10G, so one switch can serve a rack of 10G servers with a few ports left at 40G for uplinks. The 7050Q-16 is the smaller box for a 16-port 40G aggregation layer or a mixed 10G/40G edge, with 8 native SFP+ ports so you do not need breakout for a handful of 10G links. Choose 32S over 32 if you want native SFP+ ports for management or a couple of 10G uplinks. Then match airflow to the rack: -F draws air in at the port side, -R at the power supply side, and the fans and power supplies in the switch must be the same direction. Power supplies and fans are sold separately on some listings, so check what is installed, and check whether a rack kit is included since the 2-post and 4-post kits are separate parts.
Frequently asked questions
What is the difference between the 7050QX-32S and the 7050QX2-32S?
The QX2 is the later hardware revision of the same port layout, with the same 32x QSFP+ and 4x SFP+ front panel. Buyers standardizing a row usually stay on one revision so spares and EOS images line up.
Can every QSFP+ port on a 7050QX be broken out to 4x 10G?
Most can, but the exact number of breakout-capable ports and the resulting 10G port count depend on the model and the EOS release, so give us your planned port map and we will confirm it before you order.
Will a 7050QX work as a 100G switch?
No. The QSFP+ ports are 40G. For 100G QSFP28 ports look at the 7050X3 line linked above.
