Each power supply provides up to 950 watts. Therefore, the total power available
for the BladeCenter S system would be as follows:
v
Non-redundant power policy: 1900 watts
v
Power module redundancy power policy: 950 watts
v
AC power source redundancy power policy: 950 watts
Four power supplies attached to 110 V ac power sources
In this example, there are four power supplies that are attached to two separate
power sources. The power sources could each be different dedicated branch
circuits from your circuit breaker panel:
v
Power source A could be your utility provider
v
Power source B could be your UPS service
