Power and acoustics
Power supply units
The power supply subsystem is formed with a AC-DC cable power supply. The power supply pr12V and +12Vaux for non-
redundant design. There are several voltage regulators in the system to supply different voltage levels needed by different logic
devices.
The following table shows the heat dissipation of the power supply units:
Table 7. Heat dissipation
Heat dissipation 989 BTU/hr maximum (290W power supply)
Voltage 100-240 V AC, autoranging, 50/60 Hz
Acoustics
The PowerEdge T140 is a tower server appropriate for quiet office environment. The acoustical output is not noticeable under idle or
typical operating condition. Acoustical performance for two configurations are provided: typical and feature rich. The following tables
contains a summary of the configuration and acoustical performance of the PET140. Each configuration has been tested according
to Dell EMC acoustical standards for tower servers.
