For racks with port-side exhaust, the Arista DCS-7280SR3-48YC8-R is the back-to-front version of the 7280R3 48-port 25GbE switch router. It has 48 1/10/25GbE SFP ports and 8 100GbE QSFP100 uplinks in 1RU, which also run as 8 40G or 16 50G, for up to 80 25G/10G interfaces.
Arista rates it at 2.0 Tbps (4.0 Tbps full duplex) and 1 Bpps, with latency from 3.8 microseconds and a 4 GB packet buffer. Depending on the forwarding profile, it holds up to 1450K IPv4 routes in the L3 profile plus up to 1792K more with FlexRoute, and 224K MAC addresses. This SKU does not include MACsec, which Arista offers on the SR3M models.
Two hot-swap 500 W PWR-511 AC supplies (1+1) and two hot-swap fans (N+1) ship installed. Airflow is back-to-front (port-side exhaust); use PWR-511-AC-BLUE supplies and FAN-7011M-R fans for spares. The front-to-back version is DCS-7280SR3-48YC8-F. Typical power is 154 W, maximum 324 W.
Weight is 20.2 lb and size is 17.3 x 18.38 x 1.72 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.
