Environmental requirements The environmental specifications for operating this system must be satisfied before installation. Altitude The maximum altitude for system operation is 3,000 meters. For nonoperational or storage situations, the maximum altitude is 4,000 meters. Air conditioning Use separate computer room air conditioning duct work. If it is not separate from the rest of the building, it might be difficult to control cooling and air pressure levels. Duct work seals are important for maintaining a balanced air conditioning system and high static air pressure. Adequate cooling capacity means little if humidity levels increase when the ducts are exposed to warm air, producing condensation. Condensation on any disk hardware can damage the components. Any questions regarding the adequacy of airflow construction should be referred to and evaluated by a qualified structural engineer.

Environmental requirements
The environmental speci
fi
cations for operating this system must be satis
fi
ed before installation.
Altitude
The maximum altitude for system operation is 3,000 meters. For nonoperational or storage situations,
the maximum altitude is 4,000 meters.
Air conditioning
Use separate computer room air conditioning duct work. If it is not separate from the rest of the building,
it might be dif
fi
cult to control cooling and air pressure levels. Duct work seals are important for
maintaining a balanced air conditioning system and high static air pressure. Adequate cooling capacity
means little if humidity levels increase when the ducts are exposed to warm air, producing condensation.
Condensation on any disk hardware can damage the components.
Any questions regarding the adequacy of air
fl
ow construction should be referred to and evaluated by a
quali
