Note
3650-48FQM switches. These switches come with fixed fan modules and require no separate
installation.

Overview of the Fan Modules

The switch has three fan modules. Fan modules are hot-swappable. A powered switch should always
have more than one operational fan. The switch can operate with two operational fans and one
nonfunctional fan, but the failed fan should be replaced as soon as possible to avoid a service interruption
due to a second fan fault.
Three fans are required for proper cooling.
