Chapter3 Installing and Removing AC and DC Input Power Supply and Fan Modules
Power Supply Module Description
Each power supply module is cooled by three internal fans. A fan failure triggers an alarm. When a fan
fails, replace the power supply module immediately.
Caution Both slots must be occupied either by two power supply modules or a power supply and a fan module.
Do not run the switch with an empty slot unless you are replacing a faulty power supply or fan module.
Running the switch with an empty slot triggers an alarm.
