power module upgrade guidelines 533
Result:
• 7.2 IBM power units < 7.4 IBM power units
• Two 1200 W power modules will provide full power redundancy for power domain A
Power domain B worksheet (for power modules 3 and 4)
Result:
• 14.0 IBM power units > 13.4 IBM power units
• Two 2000 W power modules will provide full power redundancy for power domain B
Attention: To maintain proper system cooling, each unoccupied blade bay must contain a filler blade. To
maintain proper module cooling, each unoccupied I/O, management-module, or power-module bay must
contain a filler module. An installed power module must be powered on and must not be used as a filler
module.
