Silver 1U rack-mount network switch with 48 SFP+ ports and 4 QSFP+ uplinks

Arista Networks, Inc.

SKU CH-ENKS-NRG6K MPN DCS-7280SE-64-F

A 1 RU switch with 48 SFP+ ports at 1/10GbE and four 40GbE QSFP+ uplinks, plus management, console and USB ports, dual 500W hot-swap supplies and four hot-swap fans

  • 48 SFP+ ports deliver 1/10 GbE density for server connectivity
  • 4 QSFP+ uplinks provide 40 GbE bandwidth for aggregation
  • 1 RU form factor fits dense rack deployments
  • Dual 500 W hot-swap AC supplies ensure continuous power
  • Front-to-rear airflow matches standard data-centre cooling

Arista 7280SE 48-port 10GbE SFP+ switch

The Arista DCS-7280SE-64-F is a 1 RU network switch with 48 SFP+ ports running at 1 or 10GbE and four QSFP+ uplinks at 40GbE. It includes two hot-swappable 500W AC power supplies and four hot-swappable fans, all with front-to-rear airflow. A management port, serial console port and USB port are also provided. Rack mounts are not included.

Suits 10GbE access layers needing 40GbE uplinks

This switch fits data-centre pods that aggregate 10GbE server or storage links into 40GbE uplinks. It is not for buyers who need 100GbE uplink speeds, nor for deployments that require Power over Ethernet on the access ports. Environments that must use rear-to-front airflow should also look elsewhere.

Deciding spec: 48 SFP+ and 4 QSFP+ ports

The combination of forty-eight 1/10GbE SFP+ ports and four 40GbE QSFP+ uplinks determines whether the switch matches your cabling and bandwidth plan. If the design calls for a different port count or uplink speed, another model will be required.

Questions about this item

Which SFP+ modules are needed to use the 48 1/10GbE ports?

The 48 ports accept 1 GbE or 10 GbE SFP+ transceivers; choose modules that match the speed and fibre type of your links.

Can the four 40GbE QSFP+ uplinks connect to existing 10GbE SFP+ gear?

Yes, each QSFP+ port can be broken out into four 10 GbE lanes with a compatible breakout cable or module.

How do I confirm the switch is operating correctly after installation?

Check that both 500 W power supplies show green LEDs, all four fans spin, and the management port obtains an IP address for CLI access.
