Fan Trays (N9K-C9508-FAN)
For example, to determine the maximum amount of power that can be consumed by the modules in this switch when
fully loaded, add the maximum power consumed by two supervisor A modules (2 x 80 W = 160 W), two system controllers
(2 x 25 W = 50 W), eight 48-port 10GBASE-T line cards (8 x 540 W = 4320 W), six fabric modules (6 x 251 W = 1506
W), and three fan trays (3 x 250 W = 750 W). The total is 6786 W.
Step 2 Determine the number of power supplies required to power the modules installed in the switch by dividing the module
power requirement amount (see Step 1) by the output wattage (3000 W) of the power supplies installed in the switch.
Round up the fractional result to the nearest ones digit.
