• Clearance between racks must be at least 10 mm. If the kick plate is installed after rack placement,
allow 100 mm.

Environmental requirements

The environmental specifications for operating this system must be satisfied before installation.

Altitude specifications

The maximum altitude for system operation is 3,000 meters. For nonoperational or storage situations,
the maximum altitude is 4,000 meters. The minimum altitude for system operation is –60 meters.

Air conditioning requirements

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.
