Install/Air Flow Clearance  Maintenance of proper service clearances should allow proper air flow. 
Service Clearance  (See service clearances for the 7014 T00 Rack) 
1.    Inrush currents occur only at initial application of power, no inrush occurs during normal power off-on cycle. 
2.    For altitudes above 915 meters, the maximum temperature limit is derated by 1 degree C for every 137 meters of 
elevation above 915 meters. 
3.    See “Noise Emission Notes” on page 336 for definitions of noise emissions positions.
