Built for racks with port-side exhaust, the Arista DCS-7280SE-64-R is the back-to-front version of the 7280E 64-port switch. It has 48 1/10GbE SFP+ ports and 4 40GbE QSFP+ uplinks in 1RU, and the 40G ports can each break out to four 10GbE links.

A 9 GB packet buffer, split as 3 GB per port group, is the reason most buyers choose the 7280E for storage and bursty workloads. Capacity is 1.28 Tbps at 900 Mpps, with 3.8 microseconds latency at 64 bytes as Arista lists it. Route scale is modest, 64K IPv4 LPM, 12K IPv6 LPM, 128K to 256K MAC/host and 96K ARP/ND.

Included are two hot-swap 500 W AC supplies (1+1) and four hot-swap fans (N+1). Airflow is back-to-front (port-side exhaust); use PWR-500AC-R supplies and FAN-7000-R fans when replacing parts. The front-to-back model is DCS-7280SE-64-F. Typical draw is 263 W, maximum 381 W.

Weight is 22 lb and dimensions are 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-7280SE-64-F with the opposite airflow. A new DCS-7280SE-64-R is also available. Matching spares include the PWR-500AC-F power supply and the FAN-7000-F fan module.

This seller refurbished DCS-7280SE-64-R is tested, working, and covered by the NetworkTigers one-year warranty.
