Arista 7124S-R 24-port SFP+ switch

The Arista DCS-7124S-R is a 1 RU network switch equipped with 24 SFP+ ports operating at 1 or 10 GbE. Two hot-swappable AC power supplies and five hot-swappable fans use rear-to-front airflow. Management access is provided through two RJ-45 100/1000 ports, one RJ-45 serial console port, and one USB port. Rack mounts are not included with the unit.

Suits 10 GbE leaf deployments needing

This switch fits data-centre rows that exhaust heat toward the cold aisle. It serves networks that require 24 SFP+ ports and out-of-band management without built-in uplink modules. Buyers who need front-to-rear airflow or integrated uplink ports should evaluate other models. Environments requiring rack-mount hardware in the box must source brackets separately.

24 SFP+ ports with rear-to-front airflow

The port count and airflow direction are the decisive factors for rack compatibility. Twenty-four SFP+ interfaces support 1 GbE or 10 GbE transceivers. Rear-to-front cooling matches cold-aisle exhaust layouts. Confirm that your cabinet design and transceiver selection align with these two fixed attributes before purchase.

Questions about this item

Will the 24 SFP+ ports link at 1 GbE to my existing 1 GbE SFP modules?

Yes, each of the 24 SFP+ ports supports both 1 GbE and 10 GbE speeds, so your current 1 GbE SFP modules will work.

How can I confirm the rear-to-front airflow is operating correctly after installation?

Verify the five hot-swappable fans are spinning and check the EOS CLI for fan-status and temperature readings.

Does the unit ship with rack-mount brackets or must I order them separately?

Rack mounts are not included; the box contains the switch, two hot-swappable AC power supplies and five hot-swappable fans, all with rear-to-front airflow.
