Install/Air Flow Maintenance of a proper service clearance should allow proper air flow.
Service (See “System Service Clearances” on page 62)
1. See “Noise Emission Notes” on page 63 for definitions of noise emissions positions.
2. Noise emissions data are based on the following configuration: the drawer is mounted in a 7014 Series Model
T00 Rack and a power distribution unit is installed in the rack.
3. Inrush currents occur only at initial application of power; no inrush occurs during normal power off-on cycle.
