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.
Professionally tested and reset to factory defaults. Backed by 25+ years of enterprise trust.
This refurbished Arista DCS-7280TR-48C6-R is a 1RU switch router from the Arista 7280R Series, delivering 48 ports of 10GbE RJ-45 copper access and 6 ports of 100GbE QSFP uplinks with rear-to-front airflow. Every unit sold by WhaleyComm is professionally tested, reset to factory defaults, and inspected under our ISO 9001-certified process before it ships. The included rack kit means it is ready to mount straight out of the box.The DCS-7280TR-48C6-R is built on a Virtual Output Queue (VOQ) ASIC platform with 2.16 Tbps of non-blocking switching capacity, a 720 Mpps forwarding rate, and 4 GB of deep packet buffer memory to eliminate head-of-line blocking. A quad-core x86 CPU with 8 GB DRAM runs Arista EOS, giving teams access to full Layer 2 and Layer 3 feature sets including BGP, OSPF, IS-IS, MPLS, EVPN, VXLAN, and 128-way ECMP, as well as built-in automation tools including Zero Touch Provisioning, LANZ, DANZ, sFlow, and CloudVision integration.
At $2,495, the DCS-7280TR-48C6-R delivers enterprise-grade 100G-uplink spine connectivity at a fraction of new-unit pricing — making it a practical choice for data center leaf deployments, campus aggregation, and cloud-edge builds that demand proven hardware without the capital expense of new gear. WhaleyComm has served 5,000+ enterprise customers over 25+ years and stands behind every unit with a Lifetime Warranty.

Ideal Use Cases
Data Center Leaf Switch
The 48 x 10GbE RJ45 copper access ports and 6 x 100GbE QSFP uplinks make the DCS-7280TR-48C6-R a natural fit as a leaf node in leaf-spine architectures, connecting servers and storage while upstreaming to 100G spine switches at line rate.
Campus and Enterprise Aggregation
Full Layer 2 and Layer 3 feature support — including MLAG, OSPF, BGP, and VXLAN — allows this switch to serve as a high-performance aggregation layer in enterprise campus networks that need both copper access density and high-speed uplinks.
Internet Peering and Edge Routing
Arista EOS FlexRoute provides internet-scale routing table support, and the 7280R Series is purpose-built for BGP peering, MPLS, and Segment Routing workloads at the network edge or data center interconnect boundary.
Content Delivery and Storage Networks
The 4 GB VOQ deep packet buffer and low 3.8 µs latency are specifically suited to IP storage and content delivery environments where traffic bursts and in-cast congestion must be absorbed without packet loss.
Network Monitoring and Telemetry Deployments
Built-in LANZ, DANZ, sFlow, and IEEE 1588v2 PTP support make this switch an ideal platform for environments that require granular real-time visibility, precision timing, and traffic analytics without additional overlay tools.
Refurbished Infrastructure Refresh
Organizations upgrading access or aggregation layers can deploy the DCS-7280TR-48C6-R as a certified-refurbished alternative to new hardware, maintaining enterprise-class performance while significantly reducing capital expenditure.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
Yes. The 6 x 100GbE QSFP uplink ports support breakout configurations to 4 x 25GbE or 4 x 10GbE per port, enabling up to 24 additional 25G or 10G connections from those uplink slots. This provides significant port-density flexibility for mixed-speed environments.
The -R suffix denotes rear-to-front airflow, meaning cool air enters from the port side and exhausts from the non-port (fan) side of the chassis. This is the preferred airflow for hot-aisle/cold-aisle data center deployments where switch ports face the cold aisle. If your environment requires front-to-rear airflow, that variant is the DCS-7280TR-48C6-F.
Arista EOS is the native operating system on this platform and runs on the unit. However, certain advanced feature sets and Arista support subscriptions may require separate licensing or service agreements. Contact our engineering team at +1 214 607-4800 or sales@whaleycomm.com to discuss your specific requirements before purchase.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
Every unit goes through our ISO 9001-certified testing process: full power-on diagnostics, port-by-port functionality testing, firmware verification, factory reset, and final inspection. A Certificate of Testing ships with every unit.
