Chapter 3 Installing and Removing AC and DC Input Power Supply and Fan Modules
Fan Module Description
Fan Module Description
The fan module provides cooling and proper airflow when only one power supply module is installed.
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.
Each fan module contains three fans. The switch can operate safely if one fan fails. A fan failure triggers
an alarm. When a fan fails, replace the fan module immediately.
