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-7280SR-48C6-R is a purpose-built data center switch from Arista's 7280R series, engineered for high-performance spine-leaf and campus core deployments. Equipped with 48x 10GbE SFP+ access ports and 6x 100GbE QSFP uplink ports, this switch provides the port density and uplink bandwidth required to support modern virtualized environments, storage networks, and high-performance computing clusters.The 7280SR series leverages Arista's EOS (Extensible Operating System), a single consistent image that enables advanced automation, programmability, and telemetry. EOS supports robust APIs including eAPI and NETCONF, making this switch an excellent fit for DevOps-driven and intent-based networking environments.
The '-R' suffix denotes a rear-to-front airflow configuration, supporting hot-aisle/cold-aisle data center cooling architectures. This makes it straightforward to integrate into existing data center infrastructure without disrupting thermal management designs.
Purchasing this unit as Refurbished through WhaleyComm allows enterprises to deploy proven, high-capacity switching infrastructure at a fraction of new hardware costs. Every Refurbished unit is inspected and tested to ensure operational readiness before shipment. This is an ideal solution for organizations scaling network capacity, building out lab environments, or refreshing aging infrastructure without overextending capital budgets.
With support for L2 and L3 features, VXLAN, and advanced routing protocols, the DCS-7280SR-48C6-R is a versatile platform suited for a wide range of enterprise and service provider use cases.

Ideal Use Cases
Data Center Leaf Layer Deployment
The DCS-7280SR-48C6-R is well-suited as a leaf switch in a spine-leaf data center fabric, providing 48x 10GbE server-facing ports with high-bandwidth 100GbE uplinks to spine switches. This topology supports scalable east-west traffic patterns common in virtualized and containerized workloads.
Network Capacity Expansion
Organizations needing to add high-density 10GbE switching capacity to an existing infrastructure can deploy this unit without a full network redesign. The 6x 100GbE uplinks ensure adequate bandwidth headroom when aggregating traffic from downstream access switches or servers.
Lab and Pre-Production Environments
The cost-effective Refurbished pricing makes this switch an attractive option for building out network test labs, staging environments, or training infrastructure. Teams can work with production-equivalent hardware and EOS software without the capital outlay of new equipment.

The Arista DCS-7280SR-48C6-R runs Arista EOS, ensuring compatibility with the broader Arista 7000 series switching portfolio for consistent spine-leaf fabric deployments. It supports standard SFP+ transceivers (10GBASE-SR, 10GBASE-LR, 10GBASE-T via adapter) on access ports and QSFP transceivers (100GBASE-SR4, 100GBASE-LR4) on uplink ports. The switch integrates with Arista CloudVision for centralized network management, automation, and telemetry. EOS compatibility spans standard routing protocols (BGP, OSPF, IS-IS) and overlay technologies including VXLAN, ensuring interoperability in multi-vendor environments. Compatible with standard 19-inch rack enclosures in a 1RU form factor.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The '-R' suffix designates rear-to-front airflow, also referred to as port-side exhaust. This means cool air enters from the port side and exits the rear of the switch, which aligns with hot-aisle/cold-aisle data center cooling conventions.
This switch runs Arista EOS (Extensible Operating System), a single consistent OS image that supports advanced automation, eAPI programmability, NETCONF, and integration with network management platforms such as Arista CloudVision.
WhaleyComm provides a standard 90-day warranty on this Refurbished Arista DCS-7280SR-48C6-R, covering hardware defects and operational failures. Extended warranty options may be available — contact WhaleyComm for details.
Arista EOS includes a compatibility mode that can support select third-party transceivers, though Arista-branded or qualified optics are recommended for full feature support and stability. Please verify transceiver compatibility with your specific EOS version before deployment.
