- Four hot-swappable fans maintain front-to-rear cooling under load
- Dedicated RJ-45 management, RS-232 console and USB ports simplify local access
2 RU 32-port 400GbE OSFP Switch
The Arista Networks DCS-7280PR3-24-F is a 2 RU switch delivering 32 ports of 400GbE OSFP connectivity. It includes a 10/100/1000 RJ-45 management port, an RS-232 console port and a USB port for out-of-band control. The unit ships with two 1500 W hot-swappable AC power supplies and four hot-swappable fans, all configured for front-to-rear airflow. Arista EOS provides the operating system.
Replaces 100GbE or mixed-speed fabrics
Networks moving from 100GbE or heterogeneous 10/40/100GbE leaf-spine tiers gain a uniform 400GbE fabric with this switch. The jump is worthwhile when traffic growth demands consistent 400GbE density across 32 ports and when operational simplicity from a single-speed layer outweighs the cost of replacing existing optics and cabling. Existing 100GbE links can remain at the edge while the core consolidates at 400GbE.
Suits hyperscale and high-performance compute
This switch suits data-centre operators building dense 400GbE leaf or spine layers for AI, HPC or cloud workloads that require front-to-rear cooling alignment with standard cold-aisle layouts. Buyers needing rear-to-front airflow, integrated rack rails or a different port count should evaluate other models. Environments without 400GbE optics or OSFP cabling infrastructure will not benefit immediately.

Questions about this item
How many rack units does the 2 RU chassis occupy and are rack mounts included?
The switch occupies 2 rack units; rack mounts are not included with the unit.
What is the correct airflow orientation when inserting the two 1500 W AC power supplies and four fan modules?
Both power supplies and all four fans use front-to-rear airflow and must be installed in that orientation to maintain proper cooling.
Which field-replaceable components will need attention over the life of the switch?
The two hot-swappable 1500 W AC power supplies and four hot-swappable fan modules are the primary components that may require replacement during operation.
