Power Supply Module Overview

The switch operates with either one or two active power supply modules. A Catalyst 3850 switch that is
part of a StackPower stack operates with power supplied by other stack switches.

You can use two AC modules, two DC modules, one AC and one DC module, or one module and a blank
cover.

All power supply modules have internal fans. All switches ship with a blank cover in the second power
supply slot.
