Product Review

The Arista DCS-7048T-A-F offers high throughput at 176 Gbps and low latency at 3 microseconds, suitable for demanding network environments. However, its maximum power draw of 212W may be a concern for energy-conscious deployments. Additionally, the switch features hot-swappable power supplies and fans for increased reliability, but its operating temperature range is limited to 0-40C, potentially restricting deployment in environments with higher ambient temperatures.


The Arista DCS-7048T-A-F is designed to meet the demands of high-performance, high-density networking environments. This switch features 48 RJ45 ports supporting 100/1000 Mbps connectivity, alongside 4 SFP+ ports that offer flexibility for uplink connections with 1 or 10 Gigabit Ethernet options. This combination of ports makes it well-suited for a variety of network setups, from data centers to enterprise-level LANs. In terms of performance, the DCS-7048T-A-F delivers a throughput of 176 Gigabits per second, ensuring efficient data handling across its ports. It is capable of processing up to 132 million packets per second, with a minimal latency of 3 microseconds for 64-byte frames. This low latency and high packet processing capability make it ideal for applications requiring fast data transmission and minimal delay. Under the hood, the switch is powered by a dual-core x86 CPU, with 4 Gigabytes of system memory and 2 Gigabytes of flash storage memory. This hardware configuration provides the processing power and storage capacity necessary for running complex network operations and storing the system's software and configuration files.
  • Zero Touch Provisioning (ZTP) for simplified deployment
  • Hot-swappable power supplies and fans for uninterrupted operation and easy maintenance
  • Reversible airflow option to adapt to different rack mounting directions
The unit is equipped with two AC power supplies, ensuring redundancy and reliability. These power supplies are hot-swappable, as are the four fans, which operate with an N+1 redundancy to guarantee continuous cooling even if a fan fails. The reversible airflow option provides flexibility in cooling depending on the rack's configuration, enhancing the system's adaptability in various installation environments. The DCS-7048T-A-F is designed for durability and operational efficiency, with a typical power draw of 174W and a maximum power draw of 212W. It also includes one USB port for additional connectivity options, such as external storage or console management. With dimensions of 19 inches in width, 1.75 inches in height, and 16 inches in depth (44.5 x 4.4 x 40.64 cm), and weighing 17 lbs (7.71 kg), the switch fits standard rack units, making it easy to integrate into existing network infrastructures. Its operating temperature range from 0 to 40°C and storage temperature range from -40°C to 70°C, along with a relative humidity tolerance of 5 to 95%, ensure reliable performance in various environmental conditions. In summary, the Arista DCS-7048T-A-F is a versatile and efficient network switch that offers a mix of high-speed connectivity options, advanced features like zero-touch provisioning, and reliable hardware specifications, making it a suitable choice for organizations looking to bolster their networking capabilities with a scalable and easy-to-manage solution.
