48-port 10GbE switch with 40GbE uplinks

The Arista DCS-7050TX-64-R is a 1 RU network switch that delivers 48 RJ45 ports operating at 1 or 10GbE and four 40GbE QSFP+ uplink ports. It targets data-centre and enterprise teams needing dense 10GbE copper connectivity with high-speed aggregation links. The unit ships with dual 500W hot-swap AC power supplies and four hot-swap fans, all configured for rear-to-front airflow.

Pre-deployment checklist

Verify that your rack provides a 1 RU slot with rear-to-front cooling clearance, because the included power supplies and fans exhaust heat toward the cold aisle. Confirm that the four QSFP+ uplink ports match the transceiver type and fibre or copper cabling already in use on your aggregation layer. Ensure you have compatible RJ45 patch cables rated for 10GbE Base-T to reach the 48 access ports. Note that rack-mount rails are not included, so source suitable mounting hardware separately.

Daily operation and maintenance

Dual 500W power supplies and four fans are hot-swappable, allowing replacement without taking the switch offline during a failure. Rear-to-front airflow aligns with standard cold-aisle containment, so the exhaust direction must match your aisle layout to avoid recirculation. The front panel provides 48 RJ45 data ports, two RJ45 management ports, one RJ45 RS-232 serial console port and one USB port for local configuration or firmware loading. All ports and modules are accessible from the front for routine cable changes and module swaps.

Questions about this item

Does the switch ship with rack rails, QSFP+ transceivers or Cat6a patch cables?

The unit includes two 500 W hot-swap AC power supplies and four hot-swap fans with rear-to-front airflow. Rack mounts, QSFP+ modules and copper patch cables are not included and must be sourced separately.

Should I choose the 1/10GbE Base-T ports or the 40GbE QSFP+ uplinks for my server links?

Use the 48 RJ-45 ports for 1 GbE or 10 GbE server connections over twisted pair. Use the four QSFP+ ports for 40 GbE uplinks to aggregation or core switches with compatible transceivers and cables.

What does the 48-port 10GbE Base-T count mean for cabling distance and power draw in a live rack?

Each RJ-45 port supports up to 100 m on Cat6a at 10 GbE. The two 500 W supplies provide 1+1 redundancy for the whole chassis, including all 48 copper ports and four QSFP+ uplinks.
