Description

The Arista 7280R3A is a 1RU fixed data centre switch router built for leaf and spine roles, Internet border and peering, data centre interconnect and carrier or metro aggregation. This DCS-7280SR3AK-48YC8-R is the large-scale R3AK variant with TunnelSec hardware support, so encrypted WAN and DCI links can run at line rate on every port.

It provides 48 x SFP50 ports that accept 10G, 25G and 50G modules, plus four QSFP200 and four QSFP100 uplink ports, giving up to six 200G or eight 100G ports. Throughput is 3.6 Tbps (7.2 Tbps full duplex) at 1.35 Bpps, backed by a 4 GB packet buffer and 64 GB of system memory. Large-route R3AK scale supports over 5M IPv4 routes in hardware. Airflow is rear to front, with two hot-swap AC power supplies in 1+1 redundancy and three hot-swap fans in N+1. Typical draw is 290 W and maximum 391 W, excluding transceivers.

The switch runs Arista EOS (minimum 4.32.1) and is managed with CloudVision. TunnelSec is an EOS licensed feature that needs a licence file to enable.

FAQs

Q: Does this switch need a licence to use TunnelSec?
A: Yes. TunnelSec is an EOS licensed feature and requires a licence file to enable. This SKU includes the TunnelSec hardware support and large-route R3AK scale.

Q: What airflow does this model have?
A: This -R SKU is rear to front airflow. Matching spares are the FAN-7011H-R fan module and the PWR-1011-AC-BLUE power supply for reverse airflow.

Q: What power supplies does it use?
A: It uses two hot-swap PWR-1011 AC power supplies in 1+1 redundancy (1000 W, 100-240 VAC, 50/60 Hz, IEC C14 input). Typical draw is 290 W and maximum 391 W, excluding transceivers.

Q: Which optics work in the uplink ports?
A: The QSFP200 ports take 200G modules, and the QSFP ports also take 100G modules such as SR4, LR4, CWDM4, DR, FR, AOC and DAC. The four QSFP100 ports also accept 40G QSFP+ modules and cables. The 48 SFP ports take 10G, 25G and 50G SFP modules and cables.

Q: What EOS version does it require?
A: The minimum supported release is EOS 4.32.1. The switch is managed with Arista CloudVision.
