Fan Modules

The switch has three internal hot-swappable 12-V fan modules. The air circulation system consists of the fan modules and the power supply modules. The airflow patterns vary depending on the power supply configuration.

Figure 1-8shows the airflow patterns for the 24- and 48-port switches. The blue arrow shows cool air flow, and the red arrow shows warm air flow. When the fan modules are operating properly, a green LED is on at the top left corner of the fan assembly (viewed from the rear). 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.

Note Three fans are required for proper cooling.
