Description

The Arista DCS-7050TX3-48C8-F is a high-performance 1RU data center switch featuring 48 x 10GBaseT RJ45 ports and 8 x 100GbE QSFP ports with 2.56 Tbps throughput. Designed for leaf-spine architectures, it supports flexible port speeds from 1G to 100G with ultra-low latency starting at 800ns and 32MB shared buffer. Powered by Arista EOS, it delivers wire-speed Layer 2/3 forwarding, advanced automation, and front-to-rear airflow with redundant AC power supplies for enterprise and cloud data centers.

FAQs

Q: What port speeds are supported on the RJ45 ports?
A: The 48 x 10GBaseT RJ45 ports support auto-negotiation at 1G, 2.5G, 5G, and 10G speeds, providing flexibility for mixed-speed environments and legacy copper infrastructure.

Q: Can the QSFP ports be used for breakout configurations?
A: Yes, the 8 x 100G QSFP ports support breakout cables for 4x10GbE, 4x25GbE, or 2x50GbE configurations, allowing for flexible uplink and spine connectivity options up to 56 total logical ports.

Q: What is the difference between the F and R suffix models?
A: The F suffix denotes front-to-rear airflow (port-side intake, typical for cold-aisle deployment), while the R suffix indicates rear-to-front airflow (port-side exhaust, for hot-aisle setups). Choose based on your data center cooling design.

Q: Does this switch support Layer 3 routing?
A: Yes, the DCS-7050TX3-48C8-F supports wire-speed Layer 3 routing with protocols including OSPF, BGP, IS-IS, VRRP, and PIM, making it suitable for both leaf and spine roles in modern data centers.

Q: What are typical use cases for this switch?
A: Ideal for data center top-of-rack leaf deployments with existing copper cabling infrastructure, enterprise campus networks requiring 10G server connectivity with 100G uplinks, and environments transitioning from 1G/10G to higher-speed architectures without replacing copper infrastructure.
