Silver 1U rack-mount switch with 24 SFP+ ports and dual rear power supplies

Arista Networks, Inc.

Arista Networks, Inc. DCS-7150S-24-R 24-port 10GbE SFP+ network switch

SKU CH-57GS-J4NJZ MPN DCS-7150S-24-R

A 1 RU switch with 24 SFP+ ports at 1/10 GbE, Arista EOS, dual 460 W hot-swap AC supplies and four hot-swap fans in rear-to-front airflow

  • 24 SFP+ ports deliver 1/10GbE density for high-speed aggregation
  • 1 RU form factor fits standard racks without wasting space
  • Rear-to-front airflow matches hot-aisle/cold-aisle cooling layouts
  • Dual 460W hot-swap AC supplies keep the switch running during maintenance
  • Arista EOS provides a programmable network operating system for automation

24-port 10GbE SFP+ switch for dense rack deployments

The Arista DCS-7150S-24-R delivers twenty-four 1 and 10 Gigabit Ethernet SFP+ ports in a single rack unit. It runs Arista EOS for programmable network automation and consistent operations. The rear-to-front airflow design matches hot-aisle or cold-aisle containment layouts. This switch targets data-centre and enterprise core layers that need high port density without chassis infrastructure.

Sustained line-rate forwarding across all ports

The shared packet buffer absorbs microbursts while maintaining wire-speed performance on every active port during prolonged traffic loads. Arista EOS provides deterministic latency and jitter characteristics under continuous saturation. Hot-swappable dual 460 W power supplies keep the forwarding plane online during maintenance or supply failure. The platform is built for non-blocking throughput in leaf-spine fabrics.

Rear-to-front cooling with hot-swap redundancy

Four hot-swappable fans and two 460 W AC power supplies move air from rear to front, aligning with standard data-centre airflow conventions. Fan modules can be replaced without interrupting traffic flow. Dual power inputs provide N+1 resilience for mission-critical racks. Acoustic output scales with thermal load rather than fixed high speed.

Questions about this item

How loud and hot does the DCS-7150S-24-R run with its four rear-to-front fans and two 460W supplies operating continuously?

The switch uses four hot-swappable fans and two 460W AC power supplies, all with rear-to-front airflow, to move heat out of the rack while keeping component temperatures within design limits during 24/7 operation.

Which SFP+ transceivers and cables must I already own to populate the 24 ports on this Arista 7150 switch?

The 24 ports accept 1/10GbE SFP+ modules, so you need compatible SFP+ transceivers or direct-attach cables for each link you plan to activate.

Will the 1 RU Arista 7150 fit and cool properly in a rack that already holds older front-to-rear equipment?

This unit uses rear-to-front airflow, so it draws cool air from the rear and exhausts at the front; plan rack placement so its intake aligns with the cold aisle and its exhaust does not feed neighbouring front-to-rear gear.
