1. Find out the floor load rating of the location where you plan to install the
storage units.
Important: If you do not know or are not certain about the floor load rating of
the installation site, be sure to check with the building engineer or
another appropriate person.
2. Determine whether the floor load rating of the location meets the following
requirements:
v The minimum floor load rating used by IBM is 342 kg per m ² (70 lb. per ft ² ).
v
When you install a storage unit, which includes both base models and
expansion models, the minimum floor load rating is 361 kg per m
² (74 lb.
per ft ² ). At 342 kg per m ² (70 lb per ft ² ), the side dimension for the weight
distribution area exceeds the 76.2 cm (30 in.) allowed maximum.
v
The per caster transferred weight to a raised floor panel is 450 kg (1000 lb.).
3. Using Table 52, perform the following steps for each storage unit:
a. Find the rows that are associated with the storage unit.
b. Locate the configuration row that corresponds with the floor load rating of
the site.
c. Identify the weight distribution area needed for that storage unit and floor
load rating.
