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.

Table 4-1describes the supported internal power supply modules.
