Power Supply Module Overview

The switch operates with either one or two active power supply modules or with power supplied by an expandable power supply, XPS-2200. A Catalyst 3750-X 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.

The XPS-2200 operates in two modes:

•In StackPower mode, it supplies power to the switches in the power stack (only Catalyst 3750-X switches with IP Base image).

•In expandable power supply mode, it supplies power to a switch when the switch power supply is removed or fails. When you install or replace a power supply module, the switch software polls the device. After polling, the power supply module provides power to the switch, and the XPS-2200 is available to power other devices.

Table 3-1describes the supported internal power supply modules.
