Notes:  
1.    When an IBM-approved vapor bag and desiccant packets are used to protect the system, storage specifications 
are valid for 6 months and shipping specifications are valid for 1 month. Otherwise, storage and shipping 
specifications are valid for two weeks each. 
2.    The upper limit of the dry bulb temperature must be derated 1 degree C per 189 m (619 ft.) above 1295 m (4250 
ft.). Maximum altitude for 1.1 GHz, 1.5 GHz, and 1.7 GHz modules is 3048 m (10,000 ft.) and for 1.3 GHz 
modules is 2134 m (7000 ft).
 
  
Weight Distribution 
The following table shows dimensions and weights used to calculate floor loading for the Eserver pSeries 
690. All floor-loading calculations are intended for a raised-floor environment.

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.    The values in the table may be used with the Floor Loading Calculation Program available on the IP Website. 
4.    All floor-loading calculations are intended for a raised-floor environment.
