Floor loading estimates
Floor loading estimates should be obtained in order to plan for proper
stacking of modules. (Floor loading is the weight of the system divided by
the occupied floor arena Point loading is the local pressure exerted by the
system feet on the floor.)
Table 10 shows the floor loading estimates for stacking an SL-1 system.
The estimates given represent a fully-loaded module complete with
pedestal, maximum circuit pack alIowances, power supplies, and cables.

Floor loading estimates

(kPa)
3ne
38.1 (1.8 kPa) 11 .O (75.8 kPa)
Two 60.3 (2.8 kPa) 17.3 (119 kPa)
Three 82.4 (3.9 kPa) 23.7 (163.4 kPa)
Four 104.6 (5 kPa) 30.0 (206.8 kPa)
Note: The numbers under “LBS/FT2 (kPa)” are based on a
floor area of the system of 5.64 square feet. These numbers
do not include the weight of the optional overhead cable rack.
The numbers under “Point Load (Ibs/in2) (kPa)” are based on
distributing the system weight among four feet, each with an
area of 4.91 square inches; these numbers do not reflect the
use of optional casters.
