Description

The 7280R3A 72-port 100G switch is a 2RU fixed data centre switch router built for cloud-grade routing, secure internet peering, carrier edge VPN services, EVPN services for 5G/MEC, CIN and metro, and data centre spine and leaf designs that need deep buffers and large routing tables.

It provides 72 x QSFP100 ports, supporting up to 72 x 100G, 72 x 40G, or 102 x 50G or 25/10G interfaces using breakouts, with 7.2 Tbps throughput (14.4 Tbps full duplex), a 2.7 Bpps forwarding rate and latency from 3.8 us. Eight GB of packet buffer memory supports lossless forwarding. This R3AK variant uses the large-scale routing profile, scaling to more than 5 million IPv4 routes, and adds TunnelSec wire-speed encryption (MACsec, IPsec and VXLANsec) on every port. This SKU has front-to-rear airflow and two hot-swap AC power supplies in a 1+1 arrangement, with four N+1 hot-swap fans.

It runs Arista EOS 4.31.2 or later with EOS feature licence Group 4. The ports accept 100G optics, 40G QSFP+ and 50G, 25G or 10G through breakouts. Compatible power supplies are PWR-1513-AC and PWR-1512-AC (1500W AC), and the fan tray is FAN-7012H.

FAQs

Q: Does this switch need a separate encryption licence?
A: No. TunnelSec encryption on all ports and the large-route scale are built into the R3AK model. It runs Arista EOS with feature licence Group 4 and requires EOS 4.31.2 or later.

Q: What power supplies does it use?
A: This SKU uses AC power supplies in a 1+1 redundant arrangement. Compatible models are PWR-1513-AC and PWR-1512-AC (1500W AC). Typical draw is 406 W and maximum is 754 W.

Q: Can the QSFP100 ports run slower speeds?
A: Yes. The ports accept 100G optics and 40G QSFP+, and support 50G, 25G and 10G through breakout, up to 102 x 50G or 102 x 25/10G.

Q: How does this SKU differ from other 7280R3A models?
A: The DCS-7280CR3AK-72-F is the large-routes R3AK model with TunnelSec encryption, front-to-rear airflow and two AC power supplies. Other SKUs vary in route scale, encryption and airflow.

Q: What fan tray does it use?
A: It uses the FAN-7012H fan tray with four hot-swappable fans in an N+1 redundant arrangement.
