distances in all four directions indicate the area around the rack (minus covers)
necessary to distribute the weight beyond the perimeter of the rack.
Weight-distribution areas must not overlap with adjacent computer equipment
weight-distribution areas. You must also take into consideration the additional
weight of the cables.
For example, if the raised floor at your site could safely support 351.5 kg/m

) then the correct distance between the sides of each cabinet would be 1.016
m (40 inches). You would also maintain front and back clearances of 0.762 m (30
inches), making sure that no other equipment was placed within the area.
The Cluster 1350 cabinet footprint without covers is 0.622 3 m (24.5 inches) by
1.021 m (40.2 inches). The values shown in the Table 2 assume a maximum rack
weight of 1003 kilograms (2211 pounds). Floor loading will vary by configuration.
If you need to know the approximate point load that each caster exerts on a raised
floor panel, divide the weight of the rack by four.
