Arista Networks, Inc. DCS-7050CX3-32S-F 32x100GbE QSFP28 2x10GbE SFP+ network switch

SKU CH-Z309-J2BB7 MPN DCS-7050CX3-32S-F

A 1 RU switch with 32 100GbE QSFP28 ports, 2 10GbE SFP+ uplinks and dual 500W power supplies

  • 32 high-density 100GbE QSFP28 ports for massive throughput
  • 2 additional 1/10GbE SFP+ ports for flexible uplinks
  • Dedicated management and console ports simplify operations
  • Front-to-rear airflow with hot-swap power supplies and fans
  • Compact 1 RU form factor maximises rack density

32-port 100GbE data-centre switch

The Arista DCS-7050CX3-32S-F is a 1 RU fixed-configuration switch built for high-density 100GbE leaf and spine deployments. It provides 32 QSFP28 ports running at 100GbE, two SFP+ ports for 1 or 10GbE uplinks, and a dedicated management plane with RJ-45, serial console and USB interfaces. The unit ships with Arista EOS pre-loaded and includes two hot-swappable 500W AC power supplies plus four hot-swappable fans, all oriented for front-to-rear airflow. Rack-mount rails are not included.

Suited for 100GbE leaf-spine fabrics.

Network teams building 32-port 100GbE fabrics with 10GbE breakout uplinks will match this switch to their design. Operators who need fewer than 32 high-speed ports, who require rear-to-front cooling, or who depend on included rack rails should evaluate other models. Environments that cannot accommodate front-to-rear airflow or that lack space for a 1 RU chassis must also look elsewhere.

32 QSFP28 ports at 100GbE

The decisive specification is the 32 QSFP28 ports operating at 100GbE, which sets the maximum port density and line-rate capacity for the fabric. Confirm that the cabling plan, transceiver budget and power allocation match this port count and speed before purchase.

Questions about this item

How do I install the DCS-7050CX3-32S-F in a rack, and what step is commonly missed?

Mount the 1 RU chassis using your own rails or shelf; the unit ships without rack mounts, so you must supply compatible hardware before sliding it in.

Which components will need replacement during the switch's lifespan?

The two 500 W hot-swappable AC power supplies and four hot-swappable fans are the only field-replaceable modules; both use front-to-rear airflow.

What is the first throughput limit reached when all 32 QSFP28 ports run at 100 GbE?

The aggregate 32 x 100 GbE line-rate capacity defines the ceiling; sustained full-load traffic across every port hits that fabric limit first.
