Calculating Power Consumptio n C-3
If you have a 3C12010 ECS Coaxial module with a 3C18082
ECS-MSH converter installed in yo ur MSH chassis, you must have
at least one 375W PSU present, or two if you want resilience. The
3C18012 525W PSU does not provide the -9V supply required by
the ECS Coaxial module.
To calculate actual total current requirements, use the following
equations.
A1= (+5V current for chassis) +
(+5V current for module 1) +
(+5V current for module 2) +
(+5V current for module 3) +
.....................
(+5V current for module n)
A2= (+12V current for chassis) +
(+12V current for module 1) +
(+12V current for module 2) +
(+12V current for module 3) +
.....................
(+12V current for module n)
Consumption figures for modules can be found either in
Appendix B, or in the user guide for individual modules.
To calculate power and current consumptions for ECS modules,
remember to include the power and current consumed by the
ECS - MSH module converter.
