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.
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.
