  • 48 SFP+ ports deliver 1/10GbE connectivity
  • 6 QSFP+ uplinks provide 40GbE bandwidth
  • 1 RU form factor fits dense racks
  • 2 hot-swap 500W PSUs ensure power redundancy

48-port 10G SFP+ switch

The Arista DCS-7050SX-72Q is a 1 RU network switch providing 48 SFP+ ports that operate at 1 or 10GbE. Six QSFP+ uplink ports run at 40GbE. A management port, a serial console port and a USB port are also fitted. Two 500W hot-swap AC power supplies and four hot-swap fans with rear-to-front airflow are included.

Suited for dense 10G access with 40G uplinks

This switch fits environments that need 48 10G SFP+ connections aggregated to six 40G QSFP+ uplinks in a single rack unit. It is not suited for buyers who need more access ports than the 48 provided, who require uplink speeds other than 40G, or who need rack-mount hardware included in the package.

Rear-to-front airflow with included power supplies

The unit ships with two 500W hot-swappable AC power supplies and four hot-swappable fans, all configured for rear-to-front airflow. This cooling direction determines whether the switch matches the airflow plan of the rack row where it will be installed.

Questions about this item

Should I choose the 48-port SFP+ model or a version with fewer 10G ports and more 40G uplinks?

This model provides 48 SFP+ ports for 1G or 10G connections and six QSFP+ ports for 40G uplinks, a fixed combination in a single 1RU chassis.

What does the 10GbE SFP+ rating mean when I plug in live servers?

Each of the 48 SFP+ ports negotiates at 1GbE or 10GbE, so servers with 1G or 10G NICs connect at line rate without oversubscription on the access layer.

What does the QSFP+ interface cap at in real deployments?

The six QSFP+ uplink ports operate at 40GbE each, linking to spine switches or aggregation routers at full 40G speed per port.
