  • Dedicated RJ-45 management, RS-232 console and USB ports simplify out-of-band control

1 RU switch with 48 SFP+ and 4 QSFP+ ports

The Arista DCS-7280SE-64-R is a 1 RU network switch that provides 48 ports of 1/10 GbE SFP+ connectivity and four 40 GbE QSFP+ uplink ports. It ships with two 500 W hot-swappable AC power supplies and four hot-swappable fans, both configured for rear-to-front airflow. The unit runs Arista EOS and includes a management port, a serial console port and a USB port. Rack mounts are not included.

Suited for high-density 10 GbE access

This switch fits data-centre and enterprise racks that need 48 lines of 1 or 10 GbE over SFP+ transceivers and four 40 GbE QSFP+ uplinks for aggregation. The rear-to-front cooling design matches typical hot-aisle/cold-aisle layouts. Organisations without SFP+ or QSFP+ cabling infrastructure, or that require PoE or different port speeds, should evaluate other platforms.

48 SFP+ ports decide the access-layer density

The number of 1/10 GbE SFP+ ports is the specification that determines whether this chassis matches the required access-port count. If the design calls for more or fewer than 48 SFP+ interfaces, a different model will be needed.

Questions about this item

What comes with the DCS-7280SE-64-R and what must I source separately?

The switch ships with two 500 W hot-swappable AC power supplies and four hot-swappable fans, both rear-to-front airflow; SFP+ and QSFP+ transceivers and rack-mount rails are not included.

Which port mix should I pick for a 10 GbE access layer with 40 GbE uplinks?

This model provides 48 SFP+ ports at 1/10 GbE and four QSFP+ ports at 40 GbE, matching that exact requirement in a single 1 RU chassis.

What does the 48-port SFP+ count mean when the switch is cabled in a live rack?

You can connect up to 48 servers or downstream switches at 1 or 10 GbE per port, while the four 40 GbE QSFP+ uplinks carry aggregated traffic to the core.
