Telcordia GR-2930 This design permits equipment to be fastened directly to the platform without the need for toggle bars or supplemental bracing. Structural platforms may or may not contain panels or stringers. Data centers typically have raised flooring made up of 60 cm (2 ft) removable square tiles. The trend is towards 80–100 cm (31–39 in) void to cater for better and uniform air distribution. These provide a plenum for air to circulate below the floor, as part of the air conditioning system, as well as providing space for power cabling.
Telcordia GR-2930 Telcordia NEBS: Raised Floor Generic Requirements for Network and Data Centers, GR-2930 presents generic engineering requirements for raised floors that fall within the strict NEBS guidelines. There are many types of commercially available floors that offer a wide range of structural strength and loading capabilities, depending on component construction and the materials used. The general types of raised floors include stringer, stringerless, and structural platforms, all of which are discussed in detail in GR-2930.
Structural Problems Raised Floor Structural problems, such as rocking panels and gaps between panels, can cause significant damage to equipment and injury to personnel. Regular inspections for the structural integrity of a raised floor system can help to identify and mitigate problems. Equipment and floor damage can happen when using flooring that does not meet load demands. Load ratings range from 1,000 pounds to 25,000 pounds. Higher panels can be used on heavier areas of a floor where as lower panels can be used on lighter areas.
Structural Problems Raised Floor Many such problems can be attributed to sub-par installation. During installation, attention should be paid to the condition of the subfloor, which should be clean of debris and should be as level as possible. The walls surrounding the raised floor should be as square as possible to minimize the need for cutting raised floor panels and to minimize rocking panels and gaps.
