Specifications and Compatible Tools

The 7280R-16C delivers 100G/400G ports, 480Gbps per slot, 1200W power, and 48V DC voltage. It supports 1200W per slot, 48V DC, and 100Gbps per port. Compatible tools include Arista CloudVision 2.1 (2022) and Arista Telemetry 4.0. Avoid using with part number XYZ-12345, which is incompatible due to firmware conflicts. 2026-era testing shows that 7280R-16C units require firmware 4.7.1 or higher for optimal performance. Ensure compatibility with existing network management systems by cross-referencing model numbers.

What to Check Before Buying a Used 7280R-16C in 2026

Test power supply units with a multimeter: Output must be 1200W ±5% at 48V DC. Units failing this threshold are unsuitable.
Verify firmware version: Must be 4.7.1 or higher (2026 standard). Older versions risk compatibility with Arista CloudVision 2.1.
Inspect for physical damage: No cracks, corrosion, or burn marks on PCBs. Reject units with visible wear on fan blades.
Conduct a port integrity test using a network analyzer: 2026 benchmarks require 99.99% packet loss rate and 100Gbps throughput.
Check lifecycle metrics: Units over 5 years old may have degraded capacitors. Replace electrolytic capacitors if capacitance drops below 80% of rated value.

FAQ

Q: What’s the difference between used and refurbished 7280R-16C units?
A: Used units are pre-owned with no warranty, while refurbished units include full factory testing, firmware upgrades, and a 12-month warranty.

Q: Can I use 7280R-16C with Arista CloudVision 2.1?
A: Yes, but only if firmware is updated to 4.7.1 or higher. Units with firmware below 4.7.1 will fail to sync with CloudVision 2.1, causing 2026-era network management issues.

Q: How does the 7280R-16C compare to the 7280R-32C?
A: The 7280R-16C has 16 ports vs. 32 in the 7280R-32C. Both support 100G/400G, but the 7280R-32C requires 2026-era firmware for full compatibility with Arista Telemetry 4.0.

Q: Are there any 2026-specific risks with used 7280R-16C units?
A: Yes. 2026 decommissioned units may have firmware conflicts with newer Arista tools. Always verify firmware versions and request a 2026-era compatibility report before purchase.
