Fan Module

The fan module provides cooling and proper airflow when only one power supply module is installed. The fan module is hot-swappable.

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.
