Fan Modules
The Cisco Catalyst 9200 Series Switches supports two internal fixed 12-V fan modules and two field-replaceable
fan modules (C9200-FAN=). The C9200 models support modular fans whereas the C9200L models provide
two internal fixed fans.
For information about the type of fan module supported on different switch models, see Switch Models, on
page 1 .
The air circulation system consists of the fan modules and the power supply modules. The airflow patterns
vary depending on the power supply configuration. The switch can operate at ambient temperature if one of
the fans fail.
Figure 7: Switch Airflow Pattern
The following illustration shows the airflow pattern for the switches. The blue arrow shows cool airflow, and
the red arrow shows warm airflow.
Ethernet Management Port
You can connect the switch to a host such as a Windows workstation or a terminal server through the
10/100/1000 Ethernet management port or one of the console ports. The 10/100/1000 Ethernet out-of-band
management port is a virtual routing and forwarding (VRF) interface and uses a RJ-45 crossover or
straight-through cable.
