NEW Arista DCS-7280QR-C36-R 24x 40GB QSFP+ 12x 100GB QSFP28 B-F Airflow Switch

This is the back-to-front airflow version of the Arista 7280R 36-port switch. The DCS-7280QR-C36-R has 24 40GbE QSFP+ ports and 12 100GbE QSFP100 ports in 1RU, and breakout supports up to 36 40G, 48 25G or 144 10G interfaces.

Arista rates capacity at 4.32 Tbps and 1.44 Bpps, with latency from 3.8 microseconds. The 8 GB deep packet buffer helps on congested links, and FlexRoute supports over 1M IPv4 LPM and 928K IPv6 LPM routes plus 768K MAC entries.

Included are two hot-swap 750 W AC power supplies (1+1) with two C13-C14 cords, and four hot-swap fans (N+1). Airflow is back-to-front (port-side exhaust), so replacement parts should be FAN-7000-R fans and PWR-745AC-R supplies. The front-to-back version is DCS-7280QR-C36-F; match the switch to your rack. Typical power is 324 W, maximum 499 W.

The switch is NEBS compliant, 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.

Arista also sells the DCS-7280QR-C36-F with the opposite airflow. A seller refurbished DCS-7280QR-C36-R is also available. Matching spares include the PWR-745AC-F power supply and the FAN-7000-F fan module.

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