Description

The Arista 7280R3A is a 2RU fixed data centre switch router built for large-scale layer 2 and layer 3 cloud and enterprise data centres, service provider and carrier edge networks, secure internet peering, 5G/MEC and metro EVPN services. This TunnelSec model also suits encrypted data centre interconnect using 400G ZR optics.

It provides 54 x 400GbE QSFP-DD ports plus 2 x OSFP-LS line system ports for dense 400G-ZR and ZR+ DWDM. Throughput is 21.6 Tbps (43.2 Tbps full duplex) at 8.1 Bpps, with latency from 3.8 us and a 24 GB packet buffer. The 400G ports break out to 100G, 50G, 25G and 10G, and support 40G via QSFP+. TunnelSec delivers wire-rate MACsec, IPsec and VXLANsec encryption on all ports. This SKU has two hot-swap AC power supplies in a 1+1 arrangement and four N+1 fans with front-to-rear airflow. Typical draw is 933 W and maximum 1715 W, excluding transceivers.

It runs Arista EOS 4.29.1 or later and sits in EOS Feature License Group 5. Encryption services are an EOS licensed feature that needs a licence file to enable. Spares include the FAN-7012H-RED fan module, PWR-3001-AC-RED and PWR-3001-DC-RED power supplies, and KIT-7203 and KIT-7004-2UL rack kits.
