Can I still buy discontinued Arista models?
Yes. We carry end-of-life (EOL) Arista switches that are no longer available through other channels. We stock models from the 7050, 7280, 7500, and 7800R3 series. If you're expanding an existing fabric or need a like-for-like replacement without reconfiguring your entire stack, sourcing the same EOL model is often the most cost-effective decision.
