Service  See “Service Clearances for S80 or S85 System With T00 Style I/O Rack” 
on page 36.
 
1.    See “Noise Emission Notes” on page 336 for definitions of noise emissions positions. 
2.    Noise emissions data for Model S85 are based on a system with the doors closed. 
3.    Inrush currents occur only at initial application of power, no inrush occurs during normal power off-on cycle. 
4.    The use of the PCI SSA Multi-Initiater/RAID EL in the Model S80 and S85 I/O Drawer 10 EIA limits the system 
usage to a 28°C (82°F) environment maximum. 
5.    The upper limit of the dry bulb temperature must be derated 1 degree C per 137M (450 ft.) above 1295M (4250 
ft.) 
6.    The upper limit of the wet bulb temperature must be derated 1 degree C per 274M (882 ft.) elevation above 
1370M (4500 ft.) 
7.    For systems with FC 6120: 80/160 GB Internal Tape Drive with VXA Technology or FC 6134: 60/150 GB 16-bit 
8mm Internal Tape Drive, the maximum operating temperature is limited. For additional information about this 
limitation, refer to the following table.
