Why buy Arista from XS Network Tech?
From pre-sales consultation to same-day dispatch, we make Arista procurement fast and hassle-free. Our sales and logistics team serves government departments, data centres, and service providers sourcing new, used, and EOL Arista hardware globally so you're never stuck waiting on a distributor. All used units tested and backed by a 12-month warranty.
-
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.
