The Arista DCS-7280SRA-48C6-R is the back-to-front airflow version of the 7280RA 48-port 10GbE switch router with AlgoMatch. In 1RU it has 48 1/10GbE SFP+ ports and 6 100GbE QSFP100 uplinks, which also run as 6 40G or 24 25G, for up to 72 10G interfaces.
Arista rates it at 2.16 Tbps and 720 Mpps, with latency from 3.8 microseconds. The 4 GB deep buffer handles bursts, and FlexRoute supports over 1M IPv4 LPM and 928K IPv6 LPM routes plus 768K MAC addresses. With AlgoMatch included, it fits routing and filtering at the network edge.
Two hot-swap 500 W AC supplies (1+1) and four hot-swap fans (N+1) ship installed. Airflow is back-to-front (port-side exhaust), so spares should be PWR-500AC-R supplies and FAN-7000H-R fans. The front-to-back version is DCS-7280SRA-48C6-F. Typical power is 313 W, maximum 410 W.
The switch is NEBS compliant, weighs 19.6 lb and measures 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-7280SRA-48C6-F with the opposite airflow. A new DCS-7280SRA-48C6-R is also available. Matching spares include the PWR-500AC-F power supply and the FAN-7000H-F fan module.
This seller refurbished DCS-7280SRA-48C6-R is tested, working, and covered by the NetworkTigers one-year warranty.
