DETERMINING UNIT
LOAD
REQUIREMENTS
Review the following paragraphs that discuss unit load
requirements and module slot assignments before
installing modules.
A unit load is a measure of power used to determine the
eletrical load of the MERLIN II system. Due to variations
in system size and complexity, unit load computations
must be made to assure proper operation of the system
under all conditions.
The Power Supply Module provides 45 unit loads to each
carrier. A MERLIN II system with a basic and expansion
carrier can support 90 unit loads. If the unit load
requirement per carrier exceeds 45 unit loads, an Auxiliary
Power Unit is needed. This device connects to the Power
