Description

The Arista 7280R3A is a 2RU fixed data centre switch router built for large-scale layer 2/3 leaf and spine fabrics, service provider networks, secure internet peering, carrier edge VPN services and EVPN deployments for 5G and metro. This R3AM model adds TunnelSec, giving line-rate encryption across every port for sites that need high-bandwidth wire-speed security.

The switch provides 54 x 400G QSFP-DD ports plus 2 OSFP-LS ports, with breakout to 100G, 50G, 25G and 10G subject to transceiver and cable capabilities. It delivers 21.6 Tbps (43.2 Tbps full duplex) of throughput at 8.1 Bpps, with latency from 3.8 us and a 24 GB packet buffer. TunnelSec supports MACsec, IPsec and VXLANsec using AES-256-GCM at all interface speeds from 10G to 400G.

This SKU is the DC-powered, front-to-rear airflow variant, with two hot-swap 1+1 redundant PWR-3001-DC supplies taking -48 to -60 VDC input and four hot-swap N+1 fans (FAN-7012H). Typical and maximum system draw is 933 W and 1715 W, excluding transceivers. It runs Arista EOS 4.29.1 or later and uses the Group 5 EOS feature licence tier.

FAQs

Q: Which software and licence tier does this switch use?
A: It runs Arista EOS, with a minimum release of EOS 4.29.1, and uses the Group 5 EOS feature licence tier. TunnelSec encryption capability is part of the R3AM model.

Q: What power input does this SKU require?
A: This variant uses DC power supplies with -48 to -60 VDC input, rated at 69 A maximum at -48 V and 3000 W output. The two supplies run in a 1+1 redundant, hot-swap arrangement.

Q: Which spare parts match this switch?
A: The spare fan module is FAN-7012H-RED and the spare DC power supply is PWR-3001-DC-RED. Related accessory kits include KIT-7203, KIT-7004-2UL and KIT-GND-EXT-2RU for NEBS grounding.

Q: Which optics does it support and can the ports be broken out?
A: It supports QSFP-DD, OSFP-LS and QSFP+ optics. The 400G ports can be broken out to 100G, 50G, 25G and 10G, subject to transceiver and cable capabilities.

Q: How does this SKU differ from its sibling models?
A: This is the TunnelSec (R3AM) variant with DC power and front-to-rear airflow. The TunnelSec capability adds line-rate encryption on all ports, and the DC supplies suit sites powered from a -48 VDC plant.
