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 supplied by other stack switches.
You can use two AC modules 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.
The following table describes the supported internal power supply modules.

For information on available PoE, PoE+, and UPOE and PoE requirements, see these sections the Power
Supply Modules, on page 15.
The 350-W and 715-W AC power supply modules are autoranging units that support input voltages between
100 and 240 VAC. The 1100-W power supply module is an autoranging unit that supports input voltages
between 115 and 240 VAC.
Each AC power supply module has a power cord for connection to an AC power outlet. The 1100-W and
715-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord.
The following illustrations show the power supply modules.
