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.
Wire-speed 10GbE copper switching with full Arista EOS intelligence — professionally tested and backed for life.
This refurbished Arista DCS-7048T-A delivers 48 ports of 1/10GBASE-T copper connectivity in a compact 1RU form factor, purpose-built for high-density data center access, top-of-rack, and enterprise aggregation deployments. Each unit is professionally tested, reset to factory defaults, and fully cleaned before shipment. Available in Front-to-Back (-F) and Back-to-Front (-R) airflow configurations to align with your data center cooling architecture.The DCS-7048T-A achieves up to 960 Gbps of non-blocking switching capacity and up to 714 Mpps forwarding throughput via a cut-through architecture that keeps latency consistent across all workloads. Four 10GbE SFP+ uplink ports provide flexible fiber aggregation. Running Arista EOS, the platform supports an advanced Layer 2 and Layer 3 feature set including MLAG, VXLAN, OSPF, BGP, IS-IS, sFlow, LANZ, DANZ, ACLs, and QoS — giving network teams the automation and telemetry capabilities of a modern programmable fabric. Redundant, hot-swappable power supplies and fan modules ensure carrier-class availability.
WhaleyComm has served 5,000+ enterprise customers over 25+ years, and the DCS-7048T-A at this price point represents exceptional value for organizations seeking proven Arista performance without new-hardware cost. Certified under ISO 9001, R2v3, e-Stewards, and UNEDA, every unit we ship meets the same operational standard we have maintained since day one.

Ideal Use Cases
Top-of-Rack Server Access
The 48 copper 1/10GBASE-T ports make the DCS-7048T-A an ideal top-of-rack switch for directly connecting servers with standard copper cabling, eliminating the cost of SFP+ NICs across the rack.
Data Center Leaf Switch
With 960 Gbps non-blocking capacity and native VXLAN and EVPN support under Arista EOS, this switch fits naturally as a leaf node in a spine-leaf fabric architecture.
Enterprise Aggregation
The four 10GbE SFP+ uplinks enable high-throughput aggregation of access-layer traffic, making this switch well-suited for enterprise wiring closets and campus distribution layers that demand full Layer 3 routing.
High-Density 10GbE Copper Consolidation
Organizations transitioning servers from 1GbE to 10GbE copper can consolidate connectivity into a single 1RU switch without recabling infrastructure, preserving existing Cat6A investments.
Automated and Programmable Network Fabrics
Arista EOS provides a consistent, programmable operating environment with support for telemetry tools such as LANZ and DANZ, making this switch a strong choice for teams running network automation and streaming analytics workflows.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The only difference is airflow direction. The -F variant moves air Front-to-Back, which suits hot-aisle/cold-aisle data center layouts where cool air enters the front of the rack. The -R variant moves air Back-to-Front for the reverse configuration. All ports, performance specs, and features are identical between the two.
Yes. Running Arista EOS, the DCS-7048T-A supports VXLAN, BGP EVPN, OSPF, IS-IS, and MLAG, making it capable of participating in modern overlay and underlay fabric designs without a software upgrade or additional licensing beyond standard EOS.
Yes. The 48 copper ports support both 1GbE and 10GbE connections, while the four SFP+ uplink ports accept standard 10GbE fiber transceivers. This allows flexible connectivity between copper server access and fiber uplinks to spine or aggregation layers.
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.
