NEW Arista DCS-7280QR-C36-M-F 24x 40G QSFP+ 12x 100G QSFP F-R Airflow Switch

The -M in DCS-7280QR-C36-M-F means expanded memory plus an SSD, not MACsec. Otherwise this is the same 1RU Arista 7280R switch with 24 40GbE QSFP+ ports and 12 100GbE QSFP100 ports, supporting up to 36 40G, 48 25G or 144 10G interfaces through breakout.

The extra memory and onboard SSD help with large routing tables, logging and on-box applications. Capacity is 4.32 Tbps and 1.44 Bpps, latency from 3.8 microseconds per Arista, and the 8 GB packet buffer absorbs bursts. FlexRoute scale is over 1M IPv4 LPM and 928K IPv6 LPM routes, with 768K MAC addresses.

Two hot-swap 750 W AC supplies (1+1) and four hot-swap fans (N+1) are included. Airflow is front-to-back (port-side intake); keep FAN-7000-F fans and PWR-745AC-F supplies matched. Arista also sells the back-to-front DCS-7280QR-C36-M-R, so choose the version that fits your rack. Typical power is 324 W, maximum 499 W.

The NEBS-compliant unit weighs 21 lb and measures 19 x 20.6 x 1.75 inches. Advanced Layer 3 features such as BGP and OSPF need an Arista Enhanced L3 license, which is not included and is available from Arista partners.

A seller refurbished DCS-7280QR-C36-M-F is also available. Matching spares include the PWR-745AC-F power supply and the FAN-7000-F fan module.

This DCS-7280QR-C36-M-F is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
