Arista 7250X Series Switches

Arista 7250X Series Switches (Used & Refurbished)
The Arista 7250X Series delivers high-density 10/40GbE switching in a compact 2RU fixed-configuration platform. BrightStar Systems supplies fully tested, used and refurbished 7250X switches backed by our 1-Year In-House Warranty, helping you scale leaf-spine fabrics or aggregation layers at a fraction of new hardware cost.

With up to 64× QSFP+ 40GbE ports that can break out to hundreds of 10GbE connections, the 7250X family is ideal for dense top-of-rack, spine, and middle-of-row deployments in modern data centers running Arista EOS.
Arista 7250X Series Overview
The 7250X Series is a purpose-built 10/40GbE data center switch line designed for dense two-tier architectures. These systems provide wire-speed Layer 2/Layer 3/Layer 4 performance, low latency, and advanced features for software-driven cloud networking, virtualization, and large-scale east–west traffic patterns.

Key features of the Arista 7250X Series include:

Up to 64× QSFP+ 40GbE ports in a 2RU fixed-configuration chassis
Flexible breakout options for 10GbE fan-out (up to hundreds of 10GbE ports per chassis)
Wire-speed Layer 2/Layer 3/Layer 4 forwarding with low, predictable latency
MLAG, ECMP, and VXLAN support for scalable two-tier leaf-spine designs
Redundant hot-swappable power supplies and fans with data-center friendly airflow options

If you are standardizing on Arista in the data center, 7250X switches pair naturally with 7050X Series, 7060X Series, and modular 7500 Series platforms.

FAQ – Arista 7250X Series
Q: What roles are Arista 7250X switches best suited for?
Arista 7250X switches are typically deployed as high-density 10/40GbE spine, leaf, or aggregation switches in two-tier data center designs, especially where many 10GbE servers need to be aggregated efficiently.

Q: How is the 7250X Series different from the 7050X family?
Both are fixed-configuration Arista switches, but 7250X focuses on very high-density QSFP+ 40GbE (with 10GbE fan-out) in 2RU, while 7050X offers a wider mix of 10/25/40/100GbE port combinations in 1RU and 2RU platforms.

Q: Can 7250X ports break out to 10GbE?
Yes. QSFP+ ports on 7250X platforms can be used as native 40GbE or broken out into multiple 10GbE ports using supported fan-out cables, enabling dense 10GbE access while retaining a simpler physical fabric.

Q: Are used Arista 7250X switches suitable for production networks?
Yes. Many customers deploy used and refurbished 7250X hardware in production data centers. Our testing, cleaning, and warranty coverage are designed to make pre-owned 7250X switches a reliable choice.

Q: Does BrightStar Systems buy used Arista 7250X hardware?
Yes. We actively buy used 7250X switches and other Arista platforms. If you are refreshing or decommissioning gear, we can provide bids and handle logistics.

Q: How quickly can you ship Arista 7250X switches?
Lead times depend on configuration and current inventory, but used and refurbished 7250X switches are often available for faster shipment than new hardware. Visit our Request a Quote page for current availability.
