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.
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.
