Installation Guide for C9300X

Power Supply Modules Overview

The switch operates with either one or two active power supply modules. A switch that is part of a StackPower stack operates with power that is supplied by other stack switches. Two power supply modules can be powered up from two different phases.

You can use two AC modules or one module and blank cover. 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. It lists the Platinum certified power supply modules and the default modules that are shipped with the switch. In a switch, a mix of Platinum certified and non-Platinum certified power supply modules is supported.
