Identifying the Primary System Power Requirement
D.9 Identifying the Primary System Power Requirement
Procedure
Proceed as follows to identify the primary power requirement of a system:
1. Determine overall secondary power requirement
2. Identifying primary power requirement
power requirements of the boards/components used
+ power requirement of connected workpoint clients (analog and digital telephones),
key modules and adapters
= overall secondary power requirement
overall secondary power requirement
+ requirements of power supply units (UPSM = 30 W, PSUP/UPSC-D/UPSC-DR =
12 W respectively)
+ requirements of EPSU2/EPSU2R (10 W respectively)
= the result should be multiplied by the factor 1.2 to allow for the degree of efficiency of
the power supply.
