Clearances Front Back Left Right
Install/Air Flow Maintenance of a proper service clearance should allow proper air flow.
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 S7A, SCSI I/O Drawer 7 EIA are based on the I/O drawer mounted in a rack.
3. Inrush currents occur only at initial application of power, no inrush occurs during normal power off-on cycle.
