How to use the data collected from the request output
With the value of electrical current being drawn by each power supply, you can determine the approximate power used by
each power supply with the following equation:
P = V x I
n n
Where (n) is the power supply number, (I) is the current, and (V) is always 51.4 volts.
for supply (n).
For this scenario, the approximate power being used by each supply is provided in Table 2-1.
Table 2-1. Power supply information gathered from the sample request output in Figure 2-2
Location Current (I)
1 14.973 amps
2 12.708 amps
4 5.353 amps
5 8.904 amps
With the power value from each power supply, you can approximate the total power for the entire rack with the following
equation:
P = P + P +
t 1 2
Where P equals approximate total power.
t
By entering the total power for each power supply from Table 2-1 into the equation above, you can determine that the total
power for the entire rack in this scenario is 2155.613 watts.
