What the R in the DCS-7050SX3-48C8-R means
The R at the end of DCS-7050SX3-48C8-R is Arista's code for rear-to-front airflow: the ordering table in the data sheet reads Arista 7050X3, 48x10GbE SFP & 8x100GbE QSFP100 switch, rear-to-front air, 2xAC, and gives the front-to-rear build the F suffix instead. Replacement parts follow the same code. For an R switch the spares list names the FAN-7011M-R fan module and the PWR-511-AC-BLUE power supply, described as an Arista PSU, 1RU, AC, 500W, rear-to-front airflow, 73.5mm. The RED supply and the F fan module are the front-to-rear ones.
In the data sheet's column for the 7050SX3-48C8 the port counts are given as maximums: 8 ports of 100GbE, 16 of 50GbE, 8 of 40GbE, 16 of 25GbE, 64 of 10GbE and 48 of 1GbE, with 64 interfaces in all. Arista notes that these numbers may need break-out cables and depend on the transceivers and cables used. The switch has a quad-core x86 CPU, one management port, one RS-232 serial port (RJ-45) and one USB port, takes the LIC-FIX-1 feature licence and needs EOS 4.24.0 or later.
