Fan Module
The switch supports three internal hot-swappable 12-V fan modules (FAN-T2=) are available. The air circulation
system consists of the fan modules and the power supply modules. The airflow direction is always from front
to rear.
When the fan modules are operating properly, a green LED at the top left corner of the fan assembly (viewed
from the rear), is ON. If the fan fails, the LED turns to amber. The switch can operate with two operational
fans, but the failed fan should be replaced as soon as possible to avoid a service interruption due to a second
fan fault.

The following illustration shows the airflow pattern for the switches. The blue arrow shows cool airflow, and
the red arrow shows warm airflow.
