Note
This chapter does not apply to Catalyst 3650-24PDM and 3650-48FQM switches. These switches come
with fixed fan modules and require no separate installation.
Overview
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.
