Install/Air Flow Clearance  Maintenance of a proper service clearance should allow proper air flow. 
Service Clearance  (See service clearances for the 7014 T00 Rack) 
1.    See “Noise Emission Notes” on page 336 for definitions of noise emissions positions. 
2.    Noise emissions data are based on the following configuration: a drawer is in a T00 Rack and a power 
distribution unit is installed in the rack and the system is operating in a normal 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.
