A 1 RU switch with 48 SFP+ ports at 1/10GbE, six 40GbE QSFP+ uplinks, dual 750W hot-swap power supplies and rear-to-front airflow

  • 48 SFP+ ports deliver 1/10GbE server connectivity
  • 6 QSFP+ uplinks provide 40GbE aggregation bandwidth
  • 1 RU chassis fits dense rack deployments
  • Dual 750W hot-swap PSUs ensure power redundancy
  • Four hot-swap fans maintain rear-to-front cooling

Arista 7050SX2 48-port 10GbE switch

The Arista DCS-7050SX2-72Q-R is a 1 RU data-centre switch providing 48 SFP+ ports that operate at 1 or 10 GbE. It targets network engineers building leaf-spine fabrics or high-density access layers where 10 GbE server connectivity is required. Rear-to-front airflow matches hot-aisle/cold-aisle layouts.

10G SFP+ and 40G QSFP+ port limits

Each SFP+ port accepts 1 GbE or 10 GbE transceivers; the 6 QSFP+ uplinks run at 40 GbE only. Two RJ-45 management ports top out at 1000 Mb/s, and the serial console uses RS-232 signalling. No 25 GbE, 50 GbE or 100 GbE rates are supported on any interface.

Capacity headroom for 10G access layers

The 48 downstream ports plus 6 uplinks give a 72-port non-blocking forwarding plane suited to 10 GbE server racks with 40 GbE aggregation. Environments that need 25 GbE server links, 100 GbE uplinks or larger port counts will require a different platform.

Questions about this item

How do I decide between using the 48 SFP+ ports at 1GbE or 10GbE?

Each SFP+ port accepts 1GbE or 10GbE transceivers; choose 10GbE modules for high-throughput server links and 1GbE modules for legacy access gear.

What does the 40GbE uplink speed mean for actual throughput between this switch and the core?

The six QSFP+ ports operate at 40GbE each, providing multiple high-speed paths to the core for traffic aggregation.

Which management interfaces are available on the rear panel for out-of-band access?

Two RJ-45 10/100/1000 management ports, one RJ-45 RS-232 serial console port, and one USB port are provided for out-of-band administration.
