Four power supplies attached to 220 V ac power sources
In this example, there are four power supplies that are attached to two separate
power sources.

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: 3562 watts
v
AC power source redundancy power policy: 2900 watts
Cooling considerations
The operating environment for BladeCenter S systems must provide sufficient
temperature and humidity control to prevent BladeCenter S system thermal
failures.
Air temperature and humidity
Temperature and humidity limits exist for a BladeCenter S system.
The following table describes the permissible temperatures and humidity limits for
a BladeCenter S system when it is powered on.
Table 8. Temperature and humidity limits
Altitude Temperature Range Humidity Range
0 to 914 m (0 to 3,000 ft) 10° to 35° C (50° to 95° F) 8% to 80%
914 m to 2134 m (3,000 ft to
7,000 ft) 10° to 32° C (50° to 90° F) 8% to 80%
