Brand:

Arista

Specifications

Product Overview

The Arista DCS-7280TR-48C6-R is a next-generation, high-density Ethernet switch from the Arista 7280R Series, built for enterprise networks, top-of-rack (ToR), and aggregation layers in data centers. Featuring 48x 10G RJ45 copper ports and 6x 100G QSFP28 uplinks, this switch combines flexibility, performance, and scalability in a compact form factor.
With a switching capacity of 2.16 Terabits per second (Tbps) and a forwarding rate of 720 million packets per second (Mpps), the DCS-7280TR-48C6-R is designed to meet the performance demands of modern hybrid environments. The back-to-front airflow (B-F) configuration ensures optimized cooling for cold-aisle installations, while hot-swappable power and fan modules ensure operational reliability.

Key Features

Port Configuration: 48x 10GBase-T copper RJ45 and 6x 100G QSFP28 ports
Switching Capacity: Delivers 2.16 Tbps total bandwidth
Forwarding Rate: Processes up to 720 Mpps with minimal latency
Latency: Ultra-low at just 3.8 microseconds for real-time application performance
Flexible Deployment: Ideal for mixed copper/fiber environments and scalable enterprise cores
