Environmental Elements
The following environmental elements can affect an hp rp7405/rp7410 server installation:
• Computer room preparation
• Cooling requirements
• Humidity level
• Air conditioning ducts
• Dust and pollution control
• Electrostatic discharge (ESD) prevention
• Acoustics (noise reduction)
Computer Room Preparation
The following guidelines are recommended when preparing a computer room for an hp rp7405/rp7410 server
system:
• Locate the computer room away from the exterior walls of the building to avoid the heat gain from
windows and exterior wall surfaces.
• When exterior windows are unavoidable, use windows that are double or triple glazed and shaded to
prevent direct sunlight from entering the computer room.
• Maintain the computer room at a positive pressure relative to surrounding spaces.
• Use a vapor barrier installed around the entire computer room envelope to restrain moisture migration.
• Caulk and vapor seal all pipes and cables that penetrate the envelope.
• Use at least a 12-inch raised floor system for the most favorable room air distribution system (underfloor
distribution).
• Ensure a minimum ceiling height of 12 inches between the top of the server and the ceiling and that all
ceiling clips are in place.
Basic Air Conditioning Equipment Requirements
The cooling capacity of the installed air conditioning equipment for the computer room should be sufficient to
offset the computer equipment dissipation loads, as well as any space envelope heat gain. This equipment
should include:
• Air filtration
• Cooling or dehumidification
• Humidification
• Reheating
•Air distribution
• System controls adequate to maintain the computer room within the operating range.
Lighting and personnel must also be included. For example, a person dissipates about 450 BTUs per hour
while performing a typical computer room task.
