Install/Air Flow  Maintenance of service clearance will allow proper air flow. 
Service Clearances  See “T00 and T42 Service Clearances and Caster Location” on 
page 33 for T00 or T42 rack service clearances. 
1.    See “Noise Emission Notes” on page 336 for definitions of noise emissions positions. See noise emissions note 
4. 
2.    Inrush currents occur only at initial application of power, no inrush occurs during normal power off-on cycle. 
3.    The upper limit of the dry bulb temperature must be derated 1°C per 137 m (450 ft.) above 915 m (3000 ft.). 
4.    The upper limit of the wet bulb temperature must be derated 1°C per 274 m (900 ft. ) above 305 m (1000 ft.).
