Tested
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-7050TX-64-R is a fixed-configuration, 1U data center switch delivering 48 ports of auto-negotiating 100Mb/1Gb/10GBASE-T (RJ45) connectivity alongside 4 x 40GbE QSFP+ uplink ports. Part of the Arista 7050X Series, it ships with rear-to-front airflow and dual hot-swappable AC power supplies, making it an ideal fit for data center rows with cold-aisle intake cooling. Every unit is professionally tested and reset to factory defaults before shipment.The DCS-7050TX-64-R delivers a switching capacity of 1.28 Tbps with a forwarding rate of 960 Mpps and cut-through latency under 3 microseconds. It is powered by a quad-core x86 CPU with 4 GB of system memory, 4 GB of flash, and a 12 MB shared dynamic packet buffer pool. The switch runs Arista EOS, supporting wire-speed Layer 2 and Layer 3 forwarding, VXLAN routing and bridging, EVPN, MLAG, Zero Touch Provisioning (ZTP), and Arista Latency Analyzer (LANZ) for real-time microburst detection. Its Unified Forwarding Table (UFT) architecture allows flexible allocation between MAC, IPv4, and multicast forwarding entries.
The DCS-7050TX-64-R represents exceptional value for enterprise teams that require proven 10G copper density without new-hardware pricing. WhaleyComm has served 5,000+ enterprise customers for 25+ years, and every unit ships with our Lifetime Warranty — no time limits, no questions asked.

Ideal Use Cases
Data Center Leaf Switch
The DCS-7050TX-64-R is purpose-built for leaf-spine architectures, providing 48 high-density 10GBASE-T server-facing ports and 4 x 40GbE QSFP+ uplinks to connect directly to spine switches with wire-speed L2 and L3 forwarding.
Server Farm Top-of-Rack Deployment
The 48-port copper RJ45 design allows direct server connections using existing Cat6/Cat6a cabling, eliminating the need for additional transceivers and reducing migration costs to 10G.
Virtualized and Cloud Environments
Native VXLAN routing and bridging, EVPN, and tight integration with Arista EOS automation tools make this switch an ideal underlay fabric switch for VMware, OpenStack, and other hypervisor-driven environments.
Enterprise Core or Distribution Layer
With Layer 3 wire-speed forwarding, MLAG, ECMP, and advanced routing protocol support, the DCS-7050TX-64-R fits well as a distribution or core layer switch in mid-to-large enterprise campus and data center networks.
Network Monitoring and Analytics
The integrated Arista LANZ (Latency Analyzer) and DANZ (Data ANalyZer) features provide real-time microburst detection and deep network visibility, ideal for teams managing latency-sensitive or compliance-driven environments.
Budget-Conscious 10G Expansion
For enterprises refreshing or expanding legacy 1G infrastructure, the backwards-compatible auto-negotiating copper ports allow phased 10G adoption without replacing existing structured cabling — at a fraction of new hardware cost.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
Yes. The switch provides full wire-speed Layer 2 and Layer 3 forwarding powered by Arista EOS. It supports standard routing protocols as well as advanced features including VXLAN routing, EVPN, and MLAG for flexible data center network designs.
The -R designates rear-to-front airflow, meaning cool air is drawn in from the rear of the switch and exhausted out the front. This airflow direction is designed for data center hot-aisle containment configurations where the rear of the rack faces the cold aisle.
Yes. The 48 RJ45 ports auto-negotiate at 100Mb, 1Gb, or 10G speeds, providing backward compatibility with existing copper cabling infrastructure. However, 10GBASE-T at full 10G speeds requires Cat6a or Cat7 cabling for standard distances.
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.
