To ensure that you meet all site requirements, obtain the service of a qualified
consultant or structural engineer to help you prepare the floor.
Figure 26 provides an illustration of the Earthquake Resistance Kit (1 in the
figure) after the IBM service representative installs it on the nonraised floor. Before
the IBM service representative installs the kit, you must prepare the area shown as
3 in the figure.
Use the following steps to prepare your nonraised floor:
1. Obtain six fastener sets for each rack that uses the Earthquake Resistance Kit.
These fastener sets are used to secure the Earthquake Resistance Kit load plate.
The type of fastener set that you use can be determined by your consultant or
structural engineer. However, each bolt or stud must meet the following
specifications:
v Each fastener set must withstand 2400 lb pull force.
v The fasteners must have a dimension that fits into the load plate holes,
which are each 27 mm (1.0 in.) in diameter.
v The fasteners must be long enough to extend through and securely fasten a
load plate that is 30 mm (1.2 in.) thick. The fasteners must also be short
