For racks with port-side exhaust, the Arista DCS-7280TR-48C6-R is the back-to-front version of the 7280R 10GBASE-T switch. It has 48 100M/1G/10GBASE-T RJ-45 ports and 6 100GbE QSFP100 uplinks in 1RU, and the uplinks also run as 6 40G or 24 25G interfaces.
Arista rates it at 2.16 Tbps and 720 Mpps, with latency from 3.8 microseconds. The 4 GB deep buffer helps with bursty server traffic, and FlexRoute supports over 1M IPv4 LPM and 928K IPv6 LPM routes plus 768K MAC addresses. This model is not NEBS certified.
Included are two hot-swap 500 W AC supplies (1+1) with C13-C14 cords and four hot-swap fans (N+1). Airflow is back-to-front (port-side exhaust); replacement parts should be PWR-500AC-R supplies and FAN-7000-R fans. The front-to-back model is DCS-7280TR-48C6-F. Typical power is 290 W, maximum 405 W.
Weight is 22.2 lb and dimensions are 19 x 16 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-7280TR-48C6-F with the opposite airflow. A new DCS-7280TR-48C6-R is also available. Matching spares include the PWR-500AC-F power supply and the FAN-7000-F fan module.
