Arista 7280E Cloud Scale Switches - Refurbished, Used, and New
Arista 7280E switches are 1RU deep-buffer switches for data center leaf, aggregation and WAN edge roles where traffic bursts would overflow a shallow-buffer switch. Each 7280SE model pairs 48 SFP+ ports at 10G with high-speed uplinks: 40G QSFP+ on the 7280SE-64, 100G QSFP100 on the 7280SE-68 and 100G MXP on the 7280SE-72. All three run Arista EOS and ship with front-to-back (F) or back-to-front (R) airflow. NetworkTigers sells 7280E switches, power supplies and fan modules refurbished, used and new. Every unit is tested before it ships so it works when it arrives.

Which 7280E do I need?
The 48 SFP+ ports are the same on every model, so choose by uplink. The 7280SE-64 gives four 40G QSFP+ uplinks, which suits a 40G spine or breakout to more 10G links. The 7280SE-68 gives two 100G QSFP100 uplinks for a 100G spine using standard QSFP28 optics and cables. The 7280SE-72 gives two 100G MXP ports, a multi-speed port that uses a 24-fiber MPO connector and can run as 100G, as 40G links or as a group of 10G links, which suits a site already cabled for MPO. Then pick airflow: F pulls air in at the port side and out past the power supplies, R does the reverse. Fans and power supplies must match the switch suffix. Power supplies and fans are sold separately so you can choose AC or DC and the number you want for redundancy.
Frequently asked questions
What does deep buffer mean on a 7280E?
Each port has a large packet buffer, far larger than a typical leaf switch, so the switch absorbs bursts of traffic, such as many servers sending to one uplink at once, instead of dropping packets. That is why the 7280E is used for storage, backup and WAN-facing links.
Can I mix F and R units in one rack?
Physically yes, but one of them will blow hot air into your cold aisle. Standardize on the suffix that matches the rack, and if you must change direction, swap all fans and power supplies to the other suffix as a set.
