Forty-eight 10GBASE-T RJ-45 ports at 1GbE or 10GbE and four 10GbE SFP+ uplinks make the DCS-7050T-52-R a full-rack copper access switch in 1RU. It is part of the original 7050 series.
The switch moves 1.04 Tbps at 780 Mpps. Latency is 3.3 microseconds on copper and 800 to 1150 nanoseconds on the SFP+ uplinks, with a 9 MB shared buffer. It carries 4 GB of DRAM and 2 GB of flash; a 50 GB SSD was available on the -D variant.
Airflow is back-to-front (port-side exhaust). A front-to-back (-F) version also exists, so pick the one that fits the rack. Two AC power supplies come installed in 1+1 hot-swap, and 460W PWR-460AC-R and PWR-460DC-R are listed as spares. Four FAN-7000-R fans run N+1 and are hot-swap. All fans and supplies must share one airflow direction. Arista lists typical and maximum draw of 301W and 395W. It is 19 x 16 x 1.75 inches and 20.9 lb.
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-7050T-52-F with the opposite airflow. A new DCS-7050T-52-R is also available. Matching spares include the PWR-460AC-R power supply and the FAN-7000-R fan module.
This seller refurbished DCS-7050T-52-R is tested, working, and covered by the NetworkTigers one-year warranty.
