Site Preparation Guide, Second Edition - HP Integrity cx2620 Server

When the flooring is replaced or a new floor is installed, Tate Access Floors recommends using
the Series 1250 all-steel access floor with bolt-together stringers and 24 inches (61.0 cm) by 24
inches (61.0 cm) floor panels to support the HP installation.
NOTE: If the specific floor being evaluated or considered is other than a Tate Series 800 floor,
the specific floor manufacturer must be contacted to evaluate the floor being used.
Table 2-3 lists specifications for the Tate Access Floors Series 800 raised floor system.

Windows
Avoid housing computers in a room with windows. Sunlight entering a computer room may
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 server. Use this data as the
basic guideline for space plan developments. Also consider factors as airflow, lighting, and
equipment space requirements.
Delivery Space Requirements
There should be enough clearance to move equipment safely from the receiving area to the
computer room. Permanent obstructions, such as pillars or narrow doorways, can cause equipment
damage.
Delivery plans should include the possible removal of walls or doors.
Operational Space Requirements
Consider the following factors in addition to the basic equipment dimensions:
• Eliminate obstructions to equipment intake or exhaust flow.
• The locations of lighting fixtures and utility outlets affect sevicing 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
server cabinets, more space is needed to keep ambient air intake to the server cabinets within
the specified temperature and humidity ranges. Refer to Table 2-4 for operating ranges.
