Thermal

Four blower modules with dual blowers are located on the back of the VRTX chassis. Six fans are

located between the SAS backplane and expander cards and the system planar components. You

can check fan status using the control panel LCD or the systems management interfaces.

In chassis standby mode, all components are unpowered except the CMC, the LCD control panel,

and two fans for cooling the CMC components. For chassis standby mode, the system needs to run

one or two fans at low RPM to ensure that the CMCs are properly cooled.

PowerEdge VRTX has been consciously designed with an open office layout in mind, including its

acoustical design. Acoustic intensity has been minimized as a function of delivered airflow, and

tones (buzzes, hums, whistles) have been removed. The result is a smooth sound generally masked

by that of normal office air conditioning or conference room conversations. Certain configurations

and utilizations are quieter than others — if your environment is acoustically sensitive, Dell can help

you choose the right configuration.
