Specifications
Air intake/exhaust locations:
8 RU frame: The Maestro 8 RU frame ventilation system draws cooling air through openings on the left side. Warm air is exhausted through four fans located on the right side. The left and right sides must therefore be kept clear of obstructions. It is not necessary to leave open space above or below the chassis
Note: Heat-generating equipment must not be mounted beneath the Maestro chassis
4 RU frame: Air intake is on the left, exhaust on the right
Unless specified otherwise, the following specifications apply to a single channel (i.e., one video plus associated audio channels)
