Installing a Fan Module

Before you begin

If a fan blank module is installed, remove it as follows:

  • Press the two sides of the fan blank module handle and pull on the handles enough to unseat it from its connectors.
  • Holding the handle, pull the module out of the chassis.

  • A fan slot must be open and ready for the new fan module to be installed.
  • You must have a new fan module on hand and ready to install within one minute of removing the original fan module if the switch is operating.
  • The new fan module must have the same airflow direction as the other fan and power supply modules installed in the switch. All of these modules must have either red coloring (port-side intake airflow) or they must all have blue coloring (port-side exhaust airflow).
