• Maintain recommended humidity level and airflow rates in the computer room.
• Install conductive flooring (use conductive adhesive when laying tiles).
• Use conductive wax (if waxed floors are necessary).
• Ensure that all equipment and flooring are properly grounded and are at the same ground
potential.
• Use conductive tables and chairs.
• Use a grounded wrist strap (or other grounding method) when handling circuit boards.
• Store spare electronic modules in antistatic containers.

Acoustics

Computer equipment and air-conditioning blowers cause computer rooms to be noisy. Ambient
noise level in a computer room can be reduced as follows:
• Dropped ceiling—Cover with a commercial grade of fire-resistant, acoustic-rated, fiberglass
ceiling tile.
• Sound deadening—Cover the walls with curtains or other sound-deadening material.
• Removable partitions—Use partitions constructed of foam rubber for greatest effectiveness.

Facility Characteristics

This section contains information about facility characteristics to consider when preparing the
site for the installation and operation of the product. Facility characteristics are:

Floor Loading
The computer room floor must be able to support the combined weight of the installed product
plus the weight of the individual cabinets, cabling, and peripheral devices.
See the following table for descriptions of terms used to configure a data center's floor plan.

Average floor load
Floor loading can be an issue in both raised and nonraised flooring environments. Rolling load
can be the most detrimental in a raised flooring environment while total dead load can be an
issue for either. The information presented in this section addresses raised floor installations.
Definition
The weight of the raised panel floor system including the understructure. (expressed
2 2
in lb/ft (kg/m )).
The load that the floor system can safely support (expressed in lb/ft
The load that a floor panel can support on a 1-in
weakest point (typically the center of the panel) without the surface of the panel
deflecting more than a specified amount.
The maximum load (per floor panel) that the floor system can support without failure.
Failure is defined by floor panels breaking or bending. Ultimate load is usually stated
as load per floor panel.
The load a floor panel can support (without failure) when a wheel of specified
diameter and width is rolled across the panel.
Computed by dividing total equipment weight by the area of its footprint. (expressed

in lb/ft (kg/m )).
