Cisco 3750-X Power Supply and Cisco 3560-X Switch Power Supply Modules

The Cisco 3750-x and Cisco 3560-x switchs operate with one or two C3KX-PWR-350WAC 350W AC power supplies.  In addition the switches can run with power supplied by an expandable power supply, XPS-2200. A Cisco 3750-X switch which is connected to a StackPower stack is powered 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 C3KX-PWR-350WAC 350W AC power supply modules have internal fans. All switches ship with a blank cover in the second power supply slot.

The XPS-2200 has 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.

The C3KX-PWR-350WAC 350W 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. The 440-W DC power supply module has dual input feeds (A and B) and supports input voltages between 36 and 72 VDC. The output voltage range is 51 to 57 V.

Each C3KX-PWR-350WAC 350W AC power supply 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 DC power supply module must be wired to a DC power source.
