48-port 10GbE switch with 40GbE uplinks

The Arista DCS-7050SX-64-R is a 1 RU network switch delivering 48 ports of 1/10GbE SFP+ connectivity and four 40GbE QSFP+ uplink ports. It runs Arista EOS and includes two hot-swappable 500W AC power supplies plus four hot-swappable fans, all configured for rear-to-front airflow. A management port, serial console and USB port complete the I/O.

Suits high-density 10GbE access layers

This switch fits networks that need 48 SFP+ ports in a single rack unit with 40GbE uplinks for aggregation. Rear-to-front airflow matches cold-aisle intake designs. Buyers who need front-to-rear cooling, more than four 40GbE ports, or 100GbE interfaces should look at other models.

Rear-to-front airflow power and cooling

The included 500W power supplies and four fans all move air from rear to front. Verify that your rack layout supplies cool air at the rear of the chassis before ordering.

Questions about this item

Will the 48 SFP+ ports auto-negotiate with my existing 1 GbE transceivers?

Yes, the 48 SFP+ ports support both 1 GbE and 10 GbE speeds, so legacy 1 GbE optics will link without configuration changes.

How do I confirm the rear-to-front airflow is operating correctly after installation?

Verify the four hot-swappable fans spin and the EOS CLI shows "Fan status: Ok" with airflow direction reported as rear-to-front.

Does the shipment include rack-mount brackets and SFP+ or QSFP+ transceivers?

Rack mounts are not included; the box contains the 1 RU switch, two 500 W AC power supplies, four fans, and a console cable — transceivers must be purchased separately.
