Six fans arelocated between the SAS backplane and expander cards and the system planar components. Youcan 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 runone or two fans at low RPM to ensure that the CMCs are properly cooled.AcousticsPowerEdge VRTX has been consciously designed with an open office layout in mind, including itsacoustical design. Acoustic intensity has been minimized as a function of delivered airflow, andtones (buzzes, hums, whistles) have been removed. The result is a smooth sound generally maskedby that of normal office air conditioning or conference room conversations. Certain configurationsand utilizations are quieter than others — if your environment is acoustically sensitive, Dell can helpyou choose the right configuration.
