Arista announced end of sale for the 7050SX3-48YC8 and the 7050SX3-48C8 on July 1, 2026. The last day to order is December 31, 2026. Arista's notice sets the end of software bug fixes at December 31, 2029 and the end of support and hardware replacement at December 31, 2031.
The 7050SX3-48YC8 is a 48 port 25G switch with 100G uplinks. The successor has almost the same name with a C on the end, so it is worth reading the part number twice on any quote.

What the dates mean
Arista's end-of-sale notices give a last day to order and a date on which support ends. A switch does not stop working on either date. What changes is who stands behind it: after the support date there are no new software fixes and no hardware replacement from the maker.
The part number also carries an airflow letter, -F or -R. See airflow suffixes explained.
The replacement the maker names
Arista's notice names the DCS-7050SX3-48YC8C, DCS-7050SX3-48C8C as the replacements.

What owners do next
- Keep running it. A switch, router or firewall does not stop working on a maker's date. Hold a tested spare of the same part number so a failure is a swap and not an outage. See the Arista 7050X3 listings.
- Buy more of what you already run. Matching hardware keeps one software image, one set of optics and one spares pool across the site.
- Sell what you retire. When the replacement goes in, send us the list and we will quote the pull.
Every unit we ship is tested in-house first and carries our warranty. If the part number you need is not listed, request a quote and we will check the warehouse.
