Description

The Arista 7280R3A is a 1RU fixed data-centre switch router built for leaf, spine, Internet peering and data centre interconnect roles. This 7280SR3AM-48YC8 model adds TunnelSec, giving line-rate MACsec, IPsec and VXLANsec encryption on every port, which suits encrypted DCI links, carrier edge VPN services and 5G or metro aggregation deployments.

It provides 48 SFP50 ports that run at 50, 25 or 10G, plus 4 x QSFP200 and 4 x QSFP100 uplink ports for up to 8 x 100G or 6 x 200G. 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. This SKU is the front-to-rear airflow version with two hot-swap AC power supplies in a 1+1 arrangement and three N+1 fans. Typical power draw is 290 W, with a maximum of 391 W.

It runs Arista EOS under Feature License Group 2, with a minimum release of EOS 4.32.1. The 48 SFP ports accept SFP50, SFP28, SFP+ and SFP optics, and the uplinks accept QSFP200 and QSFP100 optics, including 40G QSFP+ and breakout use. Management is available through Arista CloudVision.

FAQs

Q: Does this switch need a separate licence for encryption?
A: No. TunnelSec encryption (MACsec, IPsec and VXLANsec) is built into the 'AM' hardware model on all ports. This SKU falls under EOS Feature License Group 2, and optional EOS software feature licences and CloudVision are separate.

Q: What optics does it support?
A: The 48 SFP ports take SFP50, SFP28, SFP+ and SFP optics for 1, 10, 25 and 50G. The QSFP200 and QSFP100 uplink ports also support 40G QSFP+ and breakout use.

Q: What power supplies and airflow does this SKU use?
A: It uses two hot-swap AC supplies (PWR-1011-AC, 1000 W, 100-240 VAC) in a 1+1 arrangement, with front-to-rear airflow. The matching fan module is FAN-7011H-F.

Q: How does it differ from other 7280R3A variants?
A: This model includes TunnelSec encryption, front-to-rear airflow and dual AC power. Other variants may differ in encryption, airflow direction or DC power.

Q: Which software release does it need?
A: It runs Arista EOS, with a minimum release of EOS 4.32.1.
