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 are based on the following configuration: the drawer is mounted in a T00 Rack and a
power distribution unit.
3. Inrush currents occur only at initial application of power, no inrush occurs during normal power off-on cycle.
