Description
Displays the enclosure available power wattage.
It is the summary of each PSU's capacity (i.e. based on the
number of PSUs and the maximum capacity of each PSU).
Each PSU supports a maximum output wattage of 1100 W
or 1400 W. Power budget in the enclosure must not exceed
2660 W.
The power budget is determined by the following formula,
power budget = (maximum output wattage of the
installed PSU x sum of the PSUs in the enclosure) x 0.95.
For example, in an enclosure with two PSUs the power
budget is (1400 W x 2 PSU) x 0.95 = 2660 W.
