Silver 1U rack-mount switch with 48 SFP+ ports and 6 QSFP+ uplinks

Arista Networks, Inc.

Arista Networks DCS-7050SX-72Q-R network switch 48x10GbE SFP+ 6x40GbE QSFP+ rear-to-front airflow

SKU CH-C1JD-AB93Y MPN DCS-7050SX-72Q-R

A 1 RU switch with 48 SFP+ ports at 1/10 GbE and six 40 GbE QSFP+ uplinks, plus dual 500 W rear-to-front power supplies and four matching fans

  • 48 SFP+ ports deliver 1/10GbE server connectivity
  • 6 QSFP+ uplinks provide 40GbE aggregation bandwidth
  • 1 RU form factor fits dense rack deployments
  • Dual 500W hot-swap PSUs ensure continuous power availability
  • Rear-to-front airflow matches hot-aisle cooling designs

Purpose-built 1 RU data-centre switch

The Arista DCS-7050SX-72Q-R is a 1 RU network switch that delivers 48 ports of 1/10GbE SFP+ connectivity and six 40GbE QSFP+ uplinks. It ships with Arista EOS, two hot-swappable 500 W AC power supplies and four hot-swappable fans, all arranged for rear-to-front airflow. Management access is provided through an RJ-45 port and an RS-232 serial console.

Suited to high-density leaf-spine deployments

Network teams building leaf-spine fabrics with 10 GbE server links and 40 GbE spine uplinks will match the port map exactly. The rear-to-front cooling direction fits racks that exhaust toward a hot aisle. Buyers needing front-to-rear airflow or a different port-speed mix should evaluate other models.

Deciding specification — 48 SFP+

The combination of forty-eight 1/10GbE SFP+ ports and six 40GbE QSFP+ ports in a single rack unit determines whether this switch fits the planned topology. If the design calls for that exact port count and speed balance, the DCS-7050SX-72Q-R meets it; otherwise a different configuration is required.

Questions about this item

How do I verify the DCS-7050SX-72Q-R is operating correctly after installation?

Check that all 48 SFP+ ports and 6 QSFP+ uplinks show link lights, confirm the two 500W power supplies report normal status in Arista EOS, and ensure the four rear-to-front fans are spinning without alarms.

What ships with the switch and what must I purchase separately?

The unit includes two 500W hot-swappable AC power supplies and four hot-swappable fans, all rear-to-front airflow; rack mounts are not included, and SFP+ or QSFP+ transceivers for the 48 10GbE and 6 40GbE ports must be bought separately.

Which airflow version should I choose for my rack layout?

Select the rear-to-front airflow model (this DCS-7050SX-72Q-R) when your rack draws cool air from the rear and exhausts toward the front aisle; choose the front-to-rear variant if your cooling flows in the opposite direction.
