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 density at a fraction of new pricing. Backed by 25 years of enterprise trust.
This refurbished Arista DCS-7148S-F is professionally tested, reset to factory defaults, and ready for immediate deployment. The DCS-7148S-F ships with dual AC power supplies and front-to-rear airflow, making it purpose-built for standard hot-aisle/cold-aisle data center rack environments. Every unit is verified through WhaleyComm's ISO 9001-certified inspection process before it ships.The DCS-7148S delivers 48 ports of 10GbE SFP+ connectivity with a non-blocking switching capacity of 960 Gbps and a forwarding rate of up to 720 Mpps. Hardware-based Layer 2 and Layer 3 switching ensures consistent wire-speed performance at every port. Ultra-low latency in the 0.6 to 0.9 microsecond range makes this platform well-suited for financial trading infrastructure, high-performance computing, and any workload where deterministic forwarding matters. The switch runs on Arista EOS, supported by a dual-core x86 CPU, 2 GB of DRAM, and 2 GB of flash storage, enabling advanced automation features including Zero Touch Provisioning and Latency Analyzer (LANZ).
For organizations building or expanding high-density 10GbE top-of-rack deployments, the refurbished DCS-7148S-F delivers proven Arista performance at a significant cost reduction versus new. WhaleyComm has served 5,000+ enterprise customers for 25+ years and stands behind every unit with a Lifetime Warranty.

Ideal Use Cases
Top-of-Rack Server and Storage Connectivity
With 48 ports of 10GbE SFP+, the DCS-7148S-F provides high-density, non-blocking connectivity for server and storage arrays at the rack edge, eliminating oversubscription in compute-heavy environments.
Financial Trading Infrastructure
Sub-microsecond latency in the 0.6 to 0.9 µs range makes this switch a strong fit for algorithmic trading platforms, market data distribution, and any environment where packet timing directly affects outcomes.
High-Performance Computing Clusters
Wire-speed Layer 2 and Layer 3 forwarding at 720 Mpps supports the low-latency, high-throughput interconnects required by HPC workloads and parallel processing clusters.
Data Center Fabric Expansion
The DCS-7148S integrates natively with Arista EOS-based fabrics, supporting MLAG, ECMP, and ZTP for consistent, automated scale-out across existing Arista environments.
Latency-Sensitive Enterprise Applications
Real-time analytics, streaming data pipelines, and latency-sensitive enterprise applications benefit from the deterministic forwarding behavior and advanced monitoring tools, including LANZ, built into Arista EOS.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The -F variant uses front-to-rear airflow, which exhausts hot air out the rear of the rack and is standard for hot-aisle/cold-aisle configurations. The -R variant uses rear-to-front airflow for facilities with reversed airflow requirements. This listing is for the DCS-7148S-F.
Yes. The DCS-7148S-F performs hardware-based Layer 2 and Layer 3 switching at wire speed across all 48 ports. Advanced routing and network features are managed through Arista EOS.
The DCS-7148S-F accepts standard 10GbE SFP+ transceivers. Arista-branded optics are recommended for full EOS compatibility and support. For transceiver validation specific to your environment, contact our engineering team at +1 214 607-4800 or sales@whaleycomm.com.
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.
