Floor loading considerations

The computer room floor must be able to support the total weight of the installed server as well as the

weight of the HP MCS as they are moved into position. The information presented in this section is

about raised floor installations.

Note:

HP cannot assume responsibility for determining the suitability of a

particular raised floor system. The customer or local agencies should

determine installation requirements. An appropriate structural engineer

should verify any floor system under consideration for a server installation.

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

equipment relative to the raised floor grid. The following guidelines are recommended:

 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 4 can be used to calculate the weight load of each HP MCS G2 unit, including installed

equipment for proper floor planning.
