Warning:

HP cannot assume responsibility for determining the suitability of a

particular raised floor system. The customer or local agencies must

determine installation requirements. An appropriate structural engineer must

verify any floor system under consideration for a server installation.

Raised floor loading is a function of the floor manufacturer’s load specification and the positioning of

the equipment relative to the raised floor grid. HP recommends the following guidelines:

• Some 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.

Table 3 can be used to calculate the weight load of each MCS 5042 unit, including installed

equipment for proper floor planning. The text in blue is included as an example. Weights can vary.

Table 4: Common floor loading terms

Term Description

Dead load The weight of the raised panel floor system, including the understructure.

Expressed in lb/ft

(kg/m

Design load The safe load that a floor panel can support on a 1 inch x 1-inch

(25 mm x 25 mm

) area at the

panels weakest point (typically the center of the panel). This value is determined by taking the

lesser value of the maximum load that can be applied without failure divided by a safety factor of

two (ultimate load) or the load at which permanent damage begins to occur (yield point).

Rolling load The load a floor panel can support (without failure) when a wheel of specified diameter and

width is rolled across the panel.

Note:

If the specific floor being evaluated or considered is a product other than a

Tate All Steel 1250 System floor, you must contact the manufacturer of the

floor to evaluate if it meets the requirements described in this section.
