up to 1560 watts, but there is no redundancy for power requirements 
above 780 watts.
Figure 24. Two AT-PWR1200 Modules for 780 to 1560 Watts, with Limited 
Redundancy
The power modules in the switches and chassis in the examples up to this 
point have been the same model. But as shown in Figure 25 on page 40, 
they can be different. The example shows a chassis that is supporting 
three switches, two of which are low-power and one is high-power.
