  • 48 SFP+ ports deliver flexible 1/10GbE connectivity
  • Two 100GbE QSFP28 uplinks provide high-speed aggregation
  • 1 RU form factor fits dense rack deployments
  • Dual 500W hot-swap AC supplies ensure redundant power

Port density and uplink capacity

The Arista DCS-7280SE-68-R is a 1 RU switch that provides 48 ports of 1/10GbE SFP+ connectivity alongside 2 ports of 100GbE QSFP100 uplink capacity. It ships with two 500W hot-swappable AC power supplies and four hot-swappable fans, all configured for rear-to-front airflow. A management port, serial console port and USB port are also included for out-of-band access.

Suitable environments and limitations

This switch suits data-centre and enterprise racks that need high-density 10GbE access with 100GbE uplinks in a single rack unit. Rear-to-front airflow matches cold-aisle intake designs. Buyers who require front-to-rear cooling, deeper port buffers, or more than two 100GbE uplinks should evaluate other platforms.

Deciding specification

The combination of 48 SFP+ ports and 2 QSFP100 uplinks in a 1 RU form factor determines whether this model fits the planned leaf or spine role. If the design calls for a different port count, uplink speed or airflow direction, another switch will be required.

Questions about this item

Will the 500W AC power supplies need scheduled replacement?

The switch includes two hot-swappable 500W AC power supplies; they can be replaced individually without downtime, and no scheduled replacement interval is defined by the manufacturer.

What limits sustained throughput on the 48 SFP+ ports?

The 48 SFP+ ports operate at 1/10GbE line rate, and the 2 x 100GbE QSFP28 uplinks provide the aggregate egress capacity for sustained traffic.

How loud are the four hot-swappable fans during continuous operation?

Four rear-to-front hot-swappable fans cool the 1 RU chassis; fan speed adjusts automatically to temperature, and the design targets typical data-centre acoustic levels.
