Windows Do not house computers in a room with windows. Sunlight entering a computer room can cause problems. Magnetic tape storage media is damaged if exposed to direct sunlight. Also, the heat generated by sunlight places an additional load on the cooling system. Space Requirements This section contains information about space requirements for the product. Use this data as the basic guideline for space plan developments. Also consider factors such as airflow, lighting, and equipment space requirements. Delivery Space Requirements The site must have enough clearance to move equipment safely from the receiving area to the computer room. Permanent obstructions such as pillars or narrow doorway's can cause equipment damage. Include the possible removal of walls or doors in the delivery plans. Operational Space Requirements Consider the following factors in addition to the basic equipment dimensions: • Eliminate obstructions to equipment intake or exhaust flow. • Determine locations of lighting fixtures and utility outlets affecting servicing operations. Plan equipment layout to take advantage of lighting and utility outlets. Do not forget to include clearance for opening and closing equipment doors. • Provide sufficient clearance around the cabinets for proper cooling airflow through the equipment. If other equipment is located so that it exhausts heated air near the cooling air intakes of the product cabinets, more space is needed to keep ambient air intake to the product cabinets within the specified temperature and humidity ranges. See Table 1-5: Typical Environments of Customer Installations for operating ranges. Additional information is available from the following section: Air Quality (page 16).

Windows
Do not house computers in a room with windows. Sunlight entering a computer room can cause
problems. Magnetic tape storage media is damaged if exposed to direct sunlight. Also, the heat
generated by sunlight places an additional load on the cooling system.
Space Requirements
This section contains information about space requirements for the product. Use this data as the
basic guideline for space plan developments. Also consider factors such as airflow, lighting, and
equipment space requirements.
Delivery Space Requirements
The site must have enough clearance to move equipment safely from the receiving area to the
computer room. Permanent obstructions such as pillars or narrow doorway’s can cause equipment
damage.
Include the possible removal of walls or doors in the delivery plans.
Operational Space Requirements
Consider the following factors in addition to the basic equipment dimensions:
•
Eliminate obstructions to equipment intake or exhaust flow.
•
Determine locations of lighting fixtures and utility outlets affecting servicing operations.
Plan equipment layout to take advantage of lighting and utility outlets. Do not forget to
include clearance for opening and closing equipment doors.
•
Provide sufficient clearance around the cabinets for proper cooling airflow through the
equipment.
If other equipment is located so that it exhausts heated air near the cooling air intakes of the
product cabinets, more space is needed to keep ambient air intake to the product cabinets within
the specified temperature and humidity ranges. See
