HP server installation.
Raised Floor Loading
Raised floor loading is a function of the manufacturer's load specification and the positioning of the
equipment relative to the raised floor grid. While Hewlett-Packard cannot assume responsibility for
determining the suitability of a particular raised floor system, it does provide information and illustrations
for the customer or local agencies to determine installation requirements.
The following guidelines are recommended:
• Because many raised floor systems do not have grid stringers between floor stands, the lateral support for
the floor stands depends on adjacent panels being in place. To avoid compromising this type of floor
system while gaining under floor access, remove only one floor panel at a time.
• Larger floor grids (bigger panels) are generally rated for lighter loads.
CAUTION Do not position or install any equipment cabinets on the raised floor system until you have
carefully examined it to verify that it is adequate to support the appropriate installation.

Expressed 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 (the center of the panel), without the surface of the panel
deflecting more than a predetermined amount.
The maximum floor panel load that the floor system can support without floor
panel(s) breaking or bending.Ultimate load is load per floor panel.
The load a floor panel can support 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. This
