The 7020TRA-48 pairs 48 100/1000BASE-T ports and six 1/10G SFP+ uplinks with a 3 GB deep packet buffer, and adds AlgoMatch for more flexible traffic classification and filtering in hardware.
It switches 216 Gbps at 162 Mpps, with latency from 3.8 microseconds, and supports Accelerated sFlow. The control plane uses 8 GB DRAM and 4 GB flash. Management connections are a 100/1000 port, an RJ-45 RS-232 console and two USB ports.
Two 500W AC supplies come installed in a 1+1 redundant pair. Spares are PWR-500AC-F (500W AC) and PWR-500-DC-F (500W DC). Four hot-swap FAN-7000-F fans in N+1 move air front-to-back (port-side intake). The back-to-front version is also available from Arista, so keep fans and supplies matched to one direction.
The 1RU chassis weighs 17 lb and measures 17.3 x 15.8 x 1.71 in. 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-7020TRA-48-R with the opposite airflow. A new DCS-7020TRA-48-F is also available. Matching spares include the PWR-500AC-F power supply and the FAN-7000-F fan module.
This seller refurbished DCS-7020TRA-48-F is tested, working, and covered by the NetworkTigers one-year warranty.
