Average Floor Loading
The average floor load value, defined in Table C-4, is not appropriate for addressing raised floor ratings at the
floor grid spacing level. However, it is useful for determining floor loading at the building level, such as the
area of solid floor or span of raised floor tiles covered by the hp rp7405/rp7410 server footprint.
Typical Raised Floor Site
This section contains an example of a computer room raised floor system that is satisfactory for the
installation of an hp rp7405/rp7410 server.
Based on specific information provided by Hewlett-Packard, Tate Access Floors has approved its Series 800
all-steel access floor with bolt-together stringers and 24 in. (61.0 cm) by 24 in. (61.0 cm) floor panels.
In the event that the flooring is being replaced or a new floor is being installed, Tate Access Floors
recommends its Series 1250 all-steel access floor with bolt-together stringers and 24 in. (61.0 cm) by 24 in.
(61.0 cm) floor panels be used to support the server 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 C-4 lists specifications for the Tate Access Floors Series 800 raised floor system.

The load that a floor panel can support on a 1-in2 (6.45 cm2)
area at the panel's weakest point (typically the center of the
panel), without the surface of the panel deflecting more than
a predetermined amount.
The maximum load (per floor panel) that the floor system can
support without failure. Failure expressed by floor panel(s)
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. This value is expressed in lb/ft2 (kg/m2).
