IBM pSeries 690 Service Manual page 155

Notes:
1. For 2 frame systems, widths of Frame A and Frame B. were added (the depth remains 1069 mm (42.1 in.), not
including frame extenders).
2. For 2 frame systems, weights are based on maximum configuration (less than addition of maximum weights for
each frame).
3. All floor-loading calculations are intended for a raised-floor environment.
The following table shows floor-loading specifications for systems with slimline covers. The values
contained in the Condition column are described following the table.

11 762 (30.0)
Definition of Conditions:
v Condition 1 indicates maximum floor loading when systems are stored cover-to-cover on all four sides with covers
installed.
v Conditions 2 and 3 indicate floor loading when the system has no side clearance (beyond side covers) on both
sides while front/back distances varied.
v Conditions 4 through 8 indicate floor loading at various points below the maximum weight-distribution distance of
762 mm (30.0 in.) from each edge of the frame.
v Conditions 9 through 10 indicate floor-loading options when the installation is limited to 342.0 kg/m
v Condition 11 is the minimum floor loading required, based on the maximum weight-distribution area (30.0 in. from
each side of the base frame).
Notes:
1. Service clearance is independent from weight distribution distance and must be at least 45 in. for the front of the
frame and 36 in. for the rear of the frame (measured from the base frame).
2. Weight-distribution areas should not be overlapped.
3. Floor-loading weight distribution distances should not exceed 762 mm (30 in.) in any direction when measured
from the base frame.
