Service  (See “Service Clearances for System in an S70, S7A, or S80 I/O Rack” on 
page 54) 
1.    See “Noise Emission Notes” on page 336 for definitions of noise emissions positions. 
2.    Noise emissions data for the Model S70 SCSI I/O Drawer 7 EIA are based on the I/O drawer mounted in a rack. 
See “S70, S7A and S80 I/O Rack” on page 54. 
3.    Inrush currents occur only at initial application of power, no inrush occurs during normal power off-on cycle. 
4.    Use of the PCI SSA Multi-Initiator/RAID EL in this S70 I/O Drawer limits the system usage to a 28°C (82°F) 
environment maximum.
