For measurement, the CR9 board is mounted on a CPCI backplane. During
measurement, the power consumption of the backplane, keyboard and the hard disk
drive are withdrawn from the results. The values are typical measured. The current
drawn from +5 V supply the CPU and all external devices. The 3.3 V supply all other
components on the CR9.
