Sample calculation for a HiPath 3550
1. Determine overall secondary power requirement
power requirements of the boards/
components used =
+ power requirement of connected work-
point clients, key modules and adapt-
ers =
= overall secondary power requirement
=
2. Identifying primary power requirement
overall secondary power requirement
=
+ UPSC-D requirement =
Allow for the degree of efficiency of the
power supply unit:
The primary power requirement of HiPath 3550 with the expansion mentioned
amounts to approximately 103.7 W.
