Two AC power supplies are installed in 1+1 hot-swap; 460W PWR-460AC-R and PWR-460DC-R are listed as spares. Four FAN-7000-R fans run N+1, hot-swappable. Every fan and supply should share one airflow direction. Arista lists typical and maximum draw of 322W and 422W. It weighs 20.9 lb at 19 x 16 x 1.75 inches.
