Description

The Arista 7280R DCS-7280QR-C36-R is a fixed-configuration 1RU data centre switch router built on a deep-buffer, virtual output queue design and running Arista EOS. It suits data centre leaf and spine roles, internet peering, and cloud or large enterprise environments that need low latency and congestion visibility.

The front panel provides 24 x 40GbE QSFP+ ports and 12 x 100GbE QSFP100 (QSFP28) ports, delivering up to 4.32 Tbps full-duplex throughput and 1.44 Bpps forwarding with 8 GB of packet buffer and latency from 3.8 us. Ports can run as up to 12x100GbE, 36x40GbE, 24x50GbE, 48x25GbE or 144x10GbE using breakout. This SKU has rear-to-front airflow and is configured with 2 x hot-swap AC power supplies in a 1+1 arrangement and 2 x C13-C14 power cords, with 4 hot-swap fans in an N+1 arrangement.

The 40G ports accept 40GBASE-SR4, LR4, ER4, UNIV, XSR4, AOC and CR4 optics and cables. The 100G ports accept 100GBASE-SR4, XSR4, SWDM4, LR, LR4, CWDM4, PSM4, DR, FR, ERL4, AOC and CR4. The replacement fan tray is FAN-7000-F/R, and the switch is managed with Arista CloudVision.
