Description

The Arista 7280R3A series is a 1RU fixed-configuration data centre switch router. This SKU adds the large routes option and line-rate TunnelSec encryption, which suits data centre spine and leaf, internet peering, data centre interconnect and carrier edge roles.

It provides 30 QSFP100/200 ports and 2 QSFP200/QSFP-DD ports, with breakout up to 2x 400G, 18x 200G, 36x 100G, 56x 50G or 56x 25/10G. Throughput is 3.6 Tbps (7.2 Tbps full duplex) at 1.35 Bpps, with latency from 3.8 us and a 4 GB packet buffer. The large routes option scales beyond 5 million IPv4 routes in the highest-scale profile using FlexRoute. This front-to-rear airflow variant has two hot-swap 1500W AC power supplies in 1+1 redundancy and three hot-swap fans in N+1.

The ports accept 10G, 25G, 50G, 100G, 200G and 400G optics and breakouts, including 400G ZR/ZR+ coherent optics, and the switch runs Arista EOS 4.32.1 or later, managed with CloudVision.

FAQs

Q: Does this switch need a licence to enable TunnelSec encryption?
A: Yes. TunnelSec is an EOS licensed feature and needs a licence file (LIC-FIX-x-ENCR) to enable. This SKU sits in EOS Feature License Group 3, and further optional feature licences are sold separately.

Q: What power supplies does this SKU use?
A: It uses two 1500W hot-swap AC power supplies (PWR-1512-AC) in 1+1 redundancy, rated 200-240 VAC at 50/60 Hz with IEC C14 inlets. Typical draw is 302 W and maximum is 481 W, excluding transceivers.

Q: Which airflow direction does this model have?
A: This -F SKU has front-to-rear airflow. A rear-to-front airflow version is available as the -R SKU.

Q: What optics and speeds do the ports support?
A: The QSFP100/200 and QSFP200/QSFP-DD ports accept 10G, 25G, 50G, 100G, 200G and 400G optics and breakouts, subject to the transceiver and cable used. They also support 400G ZR/ZR+ coherent optics.

Q: Which software version does it require?
A: It runs Arista EOS and requires version 4.32.1 or later.
