Average Floor Loading
The average floor load value 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 9000 rp3410 or HP 9000 rp3440 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 a HP 9000 rp3410 or HP 9000 rp3440 server.
Based on specific information provided by HP, 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 HP installation.
If the specific floor being evaluated or considered is other than a Tate Series 800 floor, the
NOTE
specific floor manufacturer must be contacted to evaluate the floor being used.
The following table lists specifications for the Tate Access Floors Series 800 raised floor system.

The load that a floor panel can support on a 1-in
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.
