Description

The Arista 7280R3K is a 1RU fixed-configuration Layer 2/3 data centre switch router built for 25GbE leaf switching and routing roles. It suits data centre leaf and spine deployments as well as cloud and service provider edge environments that need deep-buffer R3 series architecture.

The switch provides 48 SFP28 ports supporting 1/10/25GbE, plus 8 QSFP28 uplinks supporting 40/100GbE. The QSFP28 ports can break out to 4 x 10G or 4 x 25G for flexible connectivity. This SKU is the SR3K FlexRoute variant, which supports large-scale IPv4 and IPv6 routing tables, and the -F suffix denotes front-to-rear airflow for matching hot and cold aisle layouts.

The switch runs Arista EOS for programmability and automation, and uses redundant hot-swappable power supplies and hot-swappable fan modules. The SFP28 ports accept 1G, 10G and 25G optics and DACs, while the QSFP28 ports accept 40G and 100G optics.

FAQs

Q: What does the -F suffix mean?
A: The -F suffix denotes front-to-rear airflow. Choose this variant when the switch ports face the cold aisle.

A: It identifies the 7280R3K variant with FlexRoute, which supports large-scale IPv4 and IPv6 routing tables.

Q: Can the 100G ports be broken out into lower speeds?
A: Yes. The QSFP28 ports support breakout to 4 x 10G or 4 x 25G, and also run at 40G or 100G.

Q: What optics do the ports accept?
A: The SFP28 ports accept 1G, 10G and 25G optics and DACs. The QSFP28 ports accept 40G and 100G optics. Exact support depends on the EOS version.

Q: What power options does it use?
A: It uses redundant hot-swappable AC or DC power supplies, so power can be maintained if one supply is replaced.
