Silver 1U rack-mount switch, 32 RJ-45 ports, four SFP+ uplinks, dual 460W PSUs, rear-to-front airflow

Arista Networks, Inc.

Arista Networks, Inc. DCS-7050T-36-R 32-port 10GbE Base-T 4-port SFP+ network switch

SKU CH-R19W-KW47F MPN DCS-7050T-36-R

A 1 RU switch with 32 10GbE Base-T ports and 4 SFP+ uplinks plus rear-to-front airflow cooling

  • 32 copper ports deliver 10 GbE to servers
  • 4 SFP+ uplinks extend 10 GbE over fibre
  • 1 RU chassis fits dense rack deployments
  • Dual 460 W hot-swap PSUs keep power redundant
  • Rear-to-front airflow matches cold-aisle cooling

36-Port 10GbE Top-of-Rack Switch

The Arista DCS-7050T-36-R fits a single rack unit and provides 32 RJ-45 ports operating at 1 or 10 Gbps plus four SFP+ uplinks at the same speeds. It targets data-centre teams that need dense 10GbE copper connectivity with rear-to-front cooling for hot-aisle deployments.

Dual Hot-Swap Power and Fan Trays

Two 460 W AC power supplies and four fan modules slide in from the rear, so a failed unit can be replaced without powering down the switch. Rear-to-front airflow matches aisle-containment layouts, and the included USB, RJ-45 management and RS-232 console ports give multiple out-of-band access paths.

Copper Distance and Uplink Flexibility

10GbE Base-T links are limited to the 100-metre reach of Category 6a or better cabling, which constrains server-row topology. The four SFP+ cages accept a range of direct-attach cables or optics, but only at 1 or 10 Gbps, so higher-speed uplinks are not supported on this platform.

Questions about this item

How often will the four rear-to-front airflow fans need replacement in continuous operation?

The four hot-swappable fans can be replaced individually without powering down the switch, so only a failed unit needs swapping rather than a scheduled interval.

Which component reaches its limit first when all thirty-two 10GbE Base-T ports run at full throughput?

The 460W power supplies set the sustained ceiling; each handles up to 460 watts and the pair shares the load across all active ports.

How much heat and noise should I expect from the two 460W AC power supplies running all day?

Dual 460W hot-swap supplies with rear-to-front airflow exhaust heat out the back; fan speed ramps with temperature, so acoustics rise under heavy load.
