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 the Model R24 CPU Media Enclosure are based on the following configuration: the 
enclosure is mounted in a R00 System Rack with three 2.0GB SCSI Disk drives are installed, two SCSI Disk 
Drawers with three 2.41GB disk drives installed, a power distribution unit is installed in the rack and the system is 
operating in a nominal environment of 25°C (78 °F) 
3.    Inrush currents occur only at initial application of power, no inrush occurs during normal power off-on cycle.
