DCS-7050SX3-48YC8-F is the front-to-rear airflow version of the Arista 7050SX3-48YC8, a 1RU switch with 48 ports of 25G SFP and 8 ports of 100G QSFP100 and an overall throughput of 4 Tbps. It comes with two AC power supplies. DCS-7050SX3-48YC8-R is the rear-to-front version, and the 48YC8C models add 16 GB of memory and 32 GB of flash.
The SFP ports run at 25G or in a mix of 10G and 1G speeds, and the QSFP ports run at 100GbE or 40GbE as uplinks. Maximum port counts are 8 x 100GbE, 16 x 50GbE, 8 x 40GbE, 64 x 25GbE, 64 x 10GbE and 48 x 1GbE. There is no oversubscription, and latency is 800 ns at 1 Bpps.
A quad-core x86 CPU runs with 8 GB of memory and 8 GB of flash, and the packet buffer is 32 MB with dynamic allocation. Typical power draw is 124 W with a maximum of 301 W. Two 1+1 power supplies (PWR-511-AC-RED/BLUE) and two 1+1 hot-swap fans (FAN-7011M-F/R) keep it running. The chassis is 17.3 x 1.75 x 18.4 inches and weighs 21 lb (9.45 kg). The minimum EOS release is 4.21.6.
For this model in -F mode, the maximum operating temperature drops by 2 C per 1000 m above sea level when a QSFP above 4.5 W is installed, which matters for dense optics at altitude.
More Arista 7050X switches are in the Arista switch category, including the DCS-7050SX-64-F.
