Frequently Asked Questions

What is the difference between 7280CR2A-30 and 7280CR2A-30P?

The 7280CR2A-30P adds PoE capability to the 100GbE QSFP ports. The standard 7280CR2A-30 does not include PoE — verify your deployment requirements before ordering.

What does the -F suffix indicate?

The -F suffix indicates front-to-back airflow — air enters from the front and exits from the rear. This is suitable for cold aisle containment where the front faces the cold aisle.

The Arista DCS-7280CR2A-30-F delivers 30-port 100GbE QSFP Layer 3 switching with deep buffer and front-to-back airflow — a high-performance data center spine switch for VXLAN/EVPN fabrics with Arista EOS automation.
