Description

The Arista 7280R4 is a deep-buffered fixed switch router built for cloud, AI/ML, data centre and service provider networks. It delivers 32 x 800GbE QSFP-DD ports in a 2RU chassis, running Arista EOS with a virtual output queue architecture and a 32GB packet buffer.

This -F SKU offers 25.6 Tbps of throughput (51.2 Tbps full duplex) at up to 9.6 Bpps, with latency from 3.8 us. It adds 8 x SFP25 ports and 2 x QSFP-LS ports for line system amplifiers. The 800G ports support breakout to 400G, 200G, 100G, 50G and 25G, subject to the transceiver or cable used. It is the standard routing scale variant without encryption, with front-to-rear airflow and 2 x hot-swap AC power supplies in a 1+1 redundant arrangement. An eight-core x86 CPU, 64GB of system memory and a 480GB SSD support the control plane, and a field-replaceable supervisor module helps reduce repair time.

The 7280R4 suits spine and leaf roles in AI/ML and cloud fabrics, data centre interconnect with 400G and 800G ZR and ZR+ optics, Internet peering and border routing, and MPLS or Segment Routing transport cores. It requires EOS 4.35.0 or later and is managed with CloudVision.

FAQs

Q: Which licences does the 7280R4 use?
A: It runs Arista EOS (minimum 4.35.0) and uses Group 5 fixed-switch feature licences, such as LIC-FIX-5-E for Enhanced L3 and LIC-FIX-5-FLX for advanced routing, MPLS and EVPN scale. Encryption licences apply only to encryption-capable R4K models.

Q: What power does this switch router need?
A: It uses two PWR-3211 hot-swap 3200W power supplies in a 1+1 redundant arrangement. The AC input is 200-277 VAC at 50/60 Hz via a SAF-D connector, with a typical draw of 805 W and a maximum of 1874 W excluding transceivers.

Q: Does it support 400G and 800G ZR optics?
A: Yes. The QSFP-DD ports accept 800G, 400G and 100G modules, including 400G and 800G ZR and ZR+ coherent optics. The 2 x QSFP-LS ports host Arista AMP-ZR line system amplifiers.

Q: Can the 800G ports be broken out to lower speeds?
A: Yes. The QSFP-DD ports support breakout to 400G, 200G, 100G, 50G and 25G, subject to the capabilities of the transceiver or cable used.

Q: How does the -F SKU differ from other 7280R4 variants?
A: DCS-7280R4-32DE-F has front-to-rear airflow, 2 x AC power supplies, standard routing scale and no encryption. Encryption support is only on the 7280R4K variant.
