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 10G performance, rear-to-front airflow, professionally tested and ready to deploy.
This refurbished Arista DCS-7050SX-64-R is a 1RU top-of-rack switch from the 7050SX series, delivering 48 x 10GbE SFP+ ports and 4 x 40GbE QSFP+ uplink ports with rear-to-front airflow and dual hot-swap AC power supplies. Every unit has been professionally tested, reset to factory defaults, and inspected to ensure it performs to original Arista specification before shipping.Built on a single Trident II ASIC, the DCS-7050SX-64-R delivers 1.28 Tbps of switching capacity and a forwarding rate of 960 Mpps with cut-through latency of 550 to 650 nanoseconds. Shared packet memory of 12 MB uses Dynamic Buffer Allocation to assign up to 6.7 MB to a single congested port for lossless forwarding. The switch runs Arista EOS, supports Layer 2 and Layer 3 wire-speed forwarding, and includes VXLAN, MLAG, BGP, OSPF, IS-IS, PIM, VRRP, and up to 128-way ECMP for scalable spine-leaf architectures.
At WhaleyComm, refurbished enterprise hardware gives your organization access to proven, data-center-grade performance at a fraction of the cost of new. Backed by our Lifetime Warranty and ISO 9001-certified testing process, the DCS-7050SX-64-R is an exceptionally cost-effective way to build or expand a high-density 10G leaf fabric.

Ideal Use Cases
Top-of-Rack 10G Server Connectivity
The DCS-7050SX-64-R delivers 48 x 10GbE SFP+ ports in 1RU, making it ideal for dense server rows in data centers where maximizing per-rack 10G density is a priority.
Spine-Leaf Fabric Leaf Node
With 128-way ECMP and 64-way MLAG support, this switch is purpose-built for leaf roles in two-tier spine-leaf architectures, balancing traffic evenly at scale.
Cold-Aisle Containment Data Centers
The rear-to-front airflow design aligns with cold-aisle containment cooling strategies, drawing cool air from the rear and exhausting warm air to the front hot aisle.
VXLAN Overlay and Network Virtualization
Native VXLAN routing, bridging, and gateway support makes this switch a strong choice for teams building virtualized or multi-tenant network overlays in private cloud environments.
Enterprise Core or Aggregation Switching
Full L2 and L3 wire-speed performance combined with BGP, OSPF, and IS-IS support makes the DCS-7050SX-64-R capable of handling aggregation and campus core roles in enterprise environments.
Budget-Conscious Data Center Expansion
As a professionally tested refurbished unit, the DCS-7050SX-64-R delivers carrier-grade 10G switching capability at significantly reduced capital expenditure compared to new hardware.

WhaleyComm Certificate of Testing
Lifetime Warranty — No Time Limits. No Questions.
Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it. We have stood behind our hardware for 25 years and 5,000+ customers — that is not a marketing line, it is our operating standard.
Compatibility Details
Review supported optics, cables, software, management protocols, and environment-specific compatibility guidance.
COMPATIBLE OPTICS & CABLES
✓
The Arista DCS-7050SX-64-R is compatible with standard SFP+ transceivers (10GBASE-SR, 10GBASE-LR, 10GBASE-ER, and DAC/AOC cables) on its 48 data ports and QSFP+ transceivers or breakout cables on its 4 uplink ports.
SOFTWARE COMPATIBILITY
✓
The switch is interoperable with other Arista 7000-series platforms within a spine-leaf architecture and runs Arista EOS, which supports integration with Arista CloudVision for centralized automation and orchestration.
ADDITIONAL COMPATIBILITY
✓
Fan modules and power supplies are common across the Arista 7050X, 7060X, 7150, and 7280 series for ease of sparing.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The suffix indicates airflow direction. The -R model uses rear-to-front airflow, meaning air enters from the port side and exhausts from the power supply side — ideal for cold-aisle containment deployments. The -F model uses front-to-rear airflow for the opposite cooling configuration. Both models are otherwise identical in port count, performance, and features.
Yes. Each of the four QSFP+ ports can be operated as a native 40GbE interface or broken out into four independent 10GbE interfaces using a breakout cable, providing up to 64 total 10GbE ports in the chassis.
The DCS-7050SX-64-R runs Arista EOS with base L2 and L3 routing capabilities included. An Enhanced L3 license is available separately from Arista for additional protocol features such as BGP, OSPF, IS-IS, PIM, and NAT. Contact our team to discuss your specific requirements.
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.
