Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
The Refurbished Arista DCS-7280CR-48-R is an enterprise-grade, fixed-configuration data center switch built to handle the demands of high-density 100GbE deployments. Part of Arista's 7280 Series, this switch provides 48 front-panel 100GbE QSFP ports alongside 8 additional 40GbE QSFP+ uplink ports, making it an ideal building block for scalable spine-leaf fabric architectures.Powered by Arista's battle-tested EOS (Extensible Operating System), the DCS-7280CR-48-R delivers a consistent, programmable network operating environment with support for advanced automation, streaming telemetry, and open APIs. EOS enables network teams to integrate with modern DevOps workflows and orchestration platforms, reducing operational overhead and accelerating troubleshooting.
The rear-to-front (R) airflow variant supports hot-aisle containment data center designs, ensuring compatibility with standard enterprise cooling architectures. The redundant, hot-swappable power supplies and fan modules minimize planned and unplanned downtime, which is critical for production environments.
Purchasing this unit as Refurbished through WhaleyComm provides organizations with a cost-effective path to deploying proven 100GbE infrastructure. Each unit is inspected and tested prior to shipment, making it suitable for enterprise data centers, colocation deployments, financial services environments, and high-performance computing clusters where budget efficiency and reliability must coexist.
With its combination of port density, forwarding performance, and EOS programmability, the DCS-7280CR-48-R remains a compelling choice for organizations modernizing their network fabric without overspending.

✓
The Arista DCS-7280CR-48-R runs Arista EOS, ensuring compatibility with the broader Arista 7000 Series switch portfolio for consistent multi-chassis and fabric deployments. It supports standard 100GbE QSFP and 40GbE QSFP+ transceivers, including AOC and DAC cabling solutions. EOS's open API architecture enables integration with network automation platforms such as Ansible, Puppet, and Chef, as well as cloud orchestration tools. The switch is compatible with Arista CloudVision for centralized network management, telemetry, and change control workflows. Standard data center cabling infrastructure supporting QSFP/QSFP+ form factors is required for connectivity.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The '-R' designates rear-to-front airflow direction, meaning air flows from the rear of the chassis to the front. This configuration is designed for hot-aisle containment data center setups where cold air is supplied from the front and hot exhaust exits to the rear.
This switch runs Arista EOS (Extensible Operating System), a consistent and programmable network OS that supports advanced features including streaming telemetry, open APIs, and integration with automation and orchestration tools.
Yes, Refurbished units sold by WhaleyComm undergo inspection and basic functionality testing prior to shipment to ensure the hardware is in working order before it reaches your environment.
QSFP ports on Arista 7280 Series switches generally support speed negotiation and can be used with appropriate transceivers or DAC cables for lower-speed connections; however, we recommend verifying specific speed breakout and compatibility requirements with your Arista EOS version documentation before deployment.
