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.
In a NEBS installation, you can use two DC modules or one DC module and a blank cover.
Note
All power supply modules have internal fans. All switches ship with a blank cover in the second power supply
slot.
The following table describes the supported internal power supply modules.
