FIGURE 53. MAIN STORAGE TEST POINTS
Main Storage Addressing
Figure 54 shows the inputs and functions of SAR for
both main and bump storage addressing.
Main Storage Temperature and Humidity
The operating temperature for the main storage
unit must be between 60° and 90°F, and the relative
humidity must be between 20% and 80% with a maxi-
mum wet bulb temperature of 78°F. There can be
only a two-degree maximum difference in the tem-
perature between two arrays of one main storage
unit.
Main Storage Power Information
The +60 volt XY and Z supplies are manually vari-
able between 48 and 68 volts and are temperature-
compensated.
