1−19CM 4000 Installation and Operating Manual
3. If the system wide sum of all base and fixed loading factors is greater than or equal to 160 but less than 320,
this system would be considered a “medium” loaded system and a base multiplier of 1.5 should be used in
later calculations.
4. If the system wide sum of all base and fixed loading factors is greater than or equal to 320, this system is
considered a “heavily” loaded system and a base multiplier of 2.0 should be used in later calculations.
5. Using the base multiplier specified above based upon the system wide sum of the base and fixed loading fac-
tors, distribute the devices throughout the system not exceeding the following maximum loading for the CM
4000 processors:
S CM 4000 maximum loading: 200
Note: The base multiplier is based upon the sum of the device counts of all devices system wide, NOT upon the
devices on any single processor board. Therefore, if the sum of the device counts is 400 system wide, you must
use a base multiplier of 2.0 when configuring the system. You can not merely sum the devices connected to each
individual processor using a base multiplier of 1.0 and keep this sum under the specified maximum loading.
