This rule sets the custom field specified in parameter one based on the model rating of the PDUs within the cabinet. 

If parameter 2 is false then calculate the cabinet capacity and update the standard Cabinet Capacity field. 

If parameter 2 is true then do not update the standard Cabinet Capacity field, calculate the cabinet capacity and update parameter 1.

Redundancy is determined by the PDU custom field defined in Parameter 3. 

Parameter 3 should contain the custom field name of type single-select list where the redundancy value is populated. 

Parameter 4 contains the value that indicates which PDUs are on the side to be calculated.  

Using the sum of the PDU Continuous Rated Current multiplied by the voltage of the PDUs with the custom field defined in Parameter 3 set to the value in Parameter 4 provides the total watt capacity for the cabinet that will be used as the cabinet capacity.
