Installing the Fan

This chapter describes how to install a fan module. The following topics are included in this chapter:

• Overview of the Fan Modules, page 3-1

• Fan Module Installation, page 3-2

• Finding the Fan Module Serial Number, page 3-4

Note The contents of this chapter are not applicable to the Cisco Catalyst 3650-24PDM and Catalyst

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.

Note Three fans are required for proper cooling.
