Arista 7050 Series Switches (Used & Refurbished)
The Arista 7050 Series delivers wire-speed 10/40GbE and 1/10GBase-T switching in compact 1RU data center platforms. BrightStar Systems supplies fully tested, used and refurbished 7050 switches backed by our 1-Year In-House Warranty, helping you build or expand 10GbE and 40GbE fabrics at a fraction of new hardware cost.
With options for SFP+ 10GbE access (7050S), 1/10GBase-T copper access (7050T), and high-density 40GbE (7050Q), the 7050 family is ideal for data center leaf, ToR, and aggregation roles that need predictable performance and Arista EOS features without moving up to newer 7050X platforms.
Arista 7050 Series Overview
The Arista 7050 Series focuses on 10GbE and 40GbE connectivity in a compact 1RU form factor. 7050S models provide SFP+ access with QSFP+ uplinks, 7050T models deliver 1/10GBase-T server access, and 7050Q models offer dense 40GbE ports that can break out into multiple 10GbE links. All run Arista EOS for consistent Layer 2/Layer 3 features and automation.
Key features of the Arista 7050 Series include:
Up to 52 or 64 10GbE ports in a 1RU chassis (model-dependent)
Choices of SFP+ 10GbE, 1/10GBase-T copper, and QSFP+ 40GbE interfaces
Wire-speed Layer 2/Layer 3/Layer 4 switching with low, predictable latency
Shared packet buffer architecture for bursty data center traffic
Compact 1RU designs with hot-swappable power supplies and fans
If you’re building a broader Arista environment, many customers pair 7050 Series switches with higher-scale or newer-generation platforms such as the 7050X Series, 7060X Series, or 7280 Series.

FAQ – Arista 7050 Series
Q: What roles are Arista 7050 switches best suited for?
Arista 7050 switches are typically deployed as 10GbE and 40GbE leaf, ToR, or aggregation switches, connecting server racks and uplinking into higher-speed spine or core tiers.
Q: How is the 7050 Series different from the 7050X family?
The 7050 Series focuses on 10GbE and 40GbE using SFP+, 10GBase-T, and QSFP+ interfaces. The 7050X family is a newer generation with additional models and support for higher speeds such as 25GbE and 100GbE, but it is a distinct product line with different part numbers.
Q: Are used Arista 7050 switches suitable for production networks?
Yes. Many customers deploy used and refurbished 7050 switches in production data centers. Our lab testing, cleaning, and warranty coverage are designed to make pre-owned 7050 hardware a reliable option.
Q: Do you buy used Arista 7050 hardware?
Yes. BrightStar Systems actively buys used 7050 switches and other Arista platforms. If you are decommissioning or refreshing, we can provide bids and help you recover value from surplus gear.
Q: What optics and cables are supported on 7050 ports?
Depending on the model, 7050 switches support a mix of SFP+ 10GbE, QSFP+ 40GbE, and DAC/AOC cables. 7050T models use 1/10GBase-T copper with QSFP+ or SFP+ uplinks. We can help you select supported optics for your deployment.
Q: Can I mix Arista 7050 with other Arista 7000 Series switches?
Yes. It is common to use 7050 switches alongside 7050X, 7060X, 7170, and 7280 platforms within the same EOS-based network.
Q: How quickly can you ship Arista 7050 switches?
Lead times vary by configuration and inventory, but used and refurbished 7050 switches are often available for faster shipment than new hardware. Request a quote for current availability.
