Arista 7500 Series Switches

Arista 7500 Series Switches (Used & Refurbished)
The Arista 7500 Series delivers high-performance, modular 10/40/100GbE switching for large data centers, cloud environments, and service provider cores. BrightStar Systems supplies fully tested, used and refurbished 7500 chassis, line cards, and supervisor modules backed by our 1-Year In-House Warranty, helping you scale core, spine, and aggregation layers at a fraction of new hardware cost.

With options for 4-slot, 12-slot, and 16-slot chassis and a broad portfolio of 10/40/100GbE line cards, the 7500 family is ideal for environments that need high port density, deep buffers, and a flexible, modular architecture built on Arista EOS.
Arista 7500 Series Overview
The 7500 Series is Arista’s flagship modular switching platform, designed for non-blocking performance, high availability, and scalable multi-terabit fabrics. Chassis support redundant supervisors, fabric modules, and power supplies, while line cards cover a range of 10GbE, 40GbE, and 100GbE options for data center, core, and DCI roles.

Key features of the Arista 7500 Series include:

Modular chassis options with up to 12 or 16 line card slots (model-dependent)
High-density 10GbE, 40GbE, and 100GbE line cards with deep buffers
Non-blocking, multi-terabit switching capacity with low, predictable latency
Redundant supervisors, fabric modules, and power supplies for high availability
Arista EOS with advanced routing, EVPN-VXLAN, and automation features

If you are building a large-scale leaf-spine fabric or core network, Arista 7500 chassis can sit at the spine, core, or border, working alongside fixed 7000-series platforms such as the 7050X, 7060X, 7260X, and 7280 Series.

FAQ – Arista 7500 Series
Q: What roles are Arista 7500 switches best suited for?
Arista 7500 switches are typically deployed as modular core, spine, or large aggregation platforms in data center and service provider networks, where high port density and routing scale are required.

Q: How is the 7500 Series different from fixed 7000-series switches?
The 7500 family uses a modular chassis with interchangeable line cards, supervisors, and fabric modules, allowing you to scale capacity and port types over time. Fixed 7000-series switches are compact and cost-effective but lack the same modular expansion options.

Q: Are used Arista 7500 chassis and line cards suitable for production networks?
Yes. Many customers deploy used and refurbished 7500 hardware in production. Our testing, cleaning, and warranty coverage are designed to make pre-owned 7500 chassis and line cards a reliable option.

Q: Does BrightStar Systems buy used Arista 7500 hardware?
Yes. BrightStar Systems actively buys used 7500 chassis, line cards, and spares. If you are decommissioning or refreshing, we can provide bids and handle logistics.

Q: Can Arista 7500 be used in EVPN-VXLAN fabrics?
Yes. Depending on software and line card capabilities, Arista 7500 systems can function as spine, core, or border devices in EVPN-VXLAN designs. Our team can help validate feature support for your use case.

Q: How quickly can you ship Arista 7500 hardware?
Lead times depend on configuration and inventory, but used and refurbished 7500 chassis and line cards are often available for faster shipment than new equipment. Request a quote for current availability.
