Service  (See service clearances for the R00 System Rack) 
1.    See “Noise Emission Notes” on page 336 for definitions of noise emissions positions. 
2.    Noise emissions data for Models R10 and R20 CPU Drawers are based on a processor drawer mounted in a 
R00 System Rack. 
3.    Inrush currents occur only at initial application of power, no inrush occurs during normal power off-on cycle.
