Power attachment diagrams - 220 V ac
These power attachment diagrams show examples of how to attach to 220 V ac
power sources
Remember: You cannot mix 110 V ac power sources and 220 V ac power sources
in the same BladeCenter S chassis.
Two power supplies attached to 220 V ac power sources
In this example, there are two power supplies that are attached to separate power
sources:
v Power source A could be your utility provider
v Power source B could be your UPS service
Each power supply provides up to 1450 watts. Therefore, the total power available
for the BladeCenter S system would be as follows:
v Non-redundant power policy: 2900 watts
v AC power source redundancy power policy: 1450 watts
