  • 1 RU form factor fits standard racks without consuming extra vertical space

48-port 10GbE switch with 40GbE uplinks

The Arista DCS-7050TX-72Q-R provides 48 RJ-45 ports operating at 1 or 10GbE for dense server connectivity. Six QSFP+ uplinks deliver 40GbE aggregation for spine or core links. A 1 RU chassis fits standard racks and targets data-centre operators who need high-port-count Base-T access. It runs Arista EOS for programmable network automation.

Rear-to-front airflow with hot-swap power and fans

Two 500W hot-swappable AC supplies and four hot-swappable fans move air from rear to front, matching cold-aisle intake layouts. Components can be replaced without shutting down the switch, keeping the fabric online during maintenance. Acoustic output and thermal load scale with port utilisation and ambient temperature. The design supports continuous operation in densely populated racks.

1 RU depth with fixed mounts and management ports

Rack mounts are not included, so brackets must be sourced separately for the 1 RU form factor. Two RJ-45 management ports at 10/100/1000, an RS-232 serial console and a USB port give out-of-band access for initial provisioning and recovery. Fixed port layout means cabling plans must account for 48 Base-T and six QSFP+ connections on the same face. Buyers who need integrated rack rails or front-to-rear airflow should evaluate other models.

Questions about this item

How do I install the DCS-7050TX-72Q-R in a rack and what step is commonly missed?

The switch occupies 1 RU and uses rear-to-front airflow; the included power supplies and fans are hot-swappable but rack-mount brackets are not included and must be sourced separately.

Which components will need replacement during the life of the DCS-7050TX-72Q-R?

The two 500 W AC power supplies and four fans are hot-swappable field-replaceable units designed for rear-to-front airflow.

What limit appears first when the DCS-7050TX-72Q-R runs at full load continuously?

Sustained full load is constrained by the rear-to-front cooling capacity of the four hot-swappable fans and the 500 W power-supply budget.
