Description

The Arista 7280R4 is a 2RU deep-buffered data centre switch router from the 7th-generation 7280R4 series. It is built for cloud, AI/ML and data centre spine and leaf fabrics, Internet peering and border routing, data centre interconnect with ZR/ZR+ optics, carrier edge VPN services and metro aggregation, and it runs Arista EOS.

This SKU provides 64 x 100GbE QSFP ports and 10 x 800GbE OSFP ports, delivering 14.4 Tbps (28.8 Tbps full duplex) of throughput and a 5.4 Bpps forwarding rate, with 16 GB of packet buffer memory and latency from 3.8 us. The OSFP ports support 400G, 200G, 100G, 50G and 25G breakout modes where transceivers and cables allow, for up to 144 x 100G interfaces. It uses front-to-rear airflow, 4 hot-swap N+1 fans and 2 hot-swap PWR-2411 AC power supplies in a 1+1 redundant configuration. Typical power draw is 630 W and maximum 1317 W, excluding transceivers. A field-replaceable 7001-SUP-L supervisor module is fitted, and EOS 4.35.0 or later is required.

The switch supports 400G and 800G ZR and ZR+ coherent optics, and a dedicated QSFP-LS port supports the Arista AMP-ZR line system amplifier with the CAB-LC8-CS splitter/combiner. It is managed through CloudVision and EOS with Group 5 fixed-switch feature licences available separately.

FAQs

Q: Which software and licences does the 7280R4 use?
A: It runs Arista EOS, version 4.35.0 or later. Group 5 fixed-switch feature licences such as LIC-FIX-5-E (Enhanced L3), LIC-FIX-5-V (Virtualisation), LIC-FIX-5-Z (Monitoring and Automation) and the FLX route-scale licences are available separately.

Q: What power supplies does this model use?
A: It uses two hot-swap PWR-2411 AC power supplies in a 1+1 redundant arrangement. Each is rated at 2400 W, 93% Platinum efficiency, with a 200-240 VAC input and an IEC 60320 C20 inlet.

Q: What can the 800G OSFP ports connect to?
A: The OSFP ports support 800G and breakout to 400G, 200G, 100G, 50G and 25G where the transceivers and cables allow. They also support 400G and 800G ZR and ZR+ coherent optics for data centre interconnect.

Q: What is the QSFP-LS port used for?
A: It is a dedicated line system port for the Arista AMP-ZR amplifier, used with the CAB-LC8-CS splitter/combiner in ZR/ZR+ coherent optical deployments.

Q: What is the airflow direction of this SKU?
A: This SKU uses front-to-rear airflow, supported by four hot-swap N+1 redundant FAN-7022HQ fans. The rear-to-front variant is a separate model.

Q: Does this model support MACsec or encryption?
A: No. Encryption is not supported on this non-K model. The 7280R4K variant supports it on all QSFP and OSFP ports.
