3.1 Site Considerations The site where you install the DSN-4X00 storage array can affect its performance. Therefore, choose a site that conforms to the requirements in the following sections. 3.1.1 General Considerations Observe the following considerations when selecting a location to install the DSN-4X00 storage array. The location should be fairly cool and dry for the acceptable temperature and humidity ranges. The location should be free of strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight. The location must provide sufficient airflow to the front and back of the DSN-4X00 storage array for correct cooling. Ventilation must be sufficient to exhaust heat from the rear of the equipment. The location should offer two AC power outlets within six feet (1.82 meters) of the DSN4X00 storage array. Ideally, the two power outlets should be on separate circuits for optimum power redundancy. The location should allow for at least six inches (15.2 cm) of space at the front and back of the DSN-4X00 storage array for ventilation. Do not place the DSN-4X00 storage array next to, on top off, or below any device that generates a significant amount of heat or will block the free flow of air through the DSN4X00 storage array ventilation slots. 3.1.2 Desktop or Shelf Installation The DSN-4X00 storage array can be mounted on a desktop or shelf. Observe the following considerations for desktop or shelf installations. Select a sturdy, level surface that can support the DSN-4X00 storage array. A fully populated unit weighs approximately 35 pounds (15.8 kg) with 16 drives or 28 pounds (12.6 kg) with 12 drives (assuming 1.1 pound / 0.5 kg per drive). Allow enough ventilation space between the DSN-4X00 storage array and any other objects in the vicinity. Be sure not to block the air vents on the front and back of the DSN-4X00 storage array enclosure. Install the cables and power cords according to the procedures in the following sections. 12 Chapter 3 Installing the DSN-4000 Series PrimaryArray
