Power Supply Modules

The 24- and 48-port switches are powered through one or two internal power supply modules. The

supply modules.

Switch Power Supply Modules

The switch has two internal power supply module slots. You can use two AC modules, two DC modules,
a mixed configuration of one AC and one DC power supply module, or one power supply module and a
blank module.
The switch can operate with either one or two active power supply modules or with power supplied by
an XPS-2200. A Catalyst 3750-X switch that is in a StackPower stack can operate with power supplied
by other switches in the stack.

supply modules (except the blank modules) have internal fans. All switches ship with a blank power
supply module in the second power supply slot.
Do not operate the switch with one power supply module slot empty. For proper chassis cooling, both
Caution
power supply module slots must be populated.
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. 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 51–57 V.
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
DC-power supply module must be wired to a DC-power source.
The XPS-2200 powers connected switches when the power supply is removed or fails. When a new
switch power supply is installed, the switch software polls the device. The switch power supply again
provides power, and the XPS-2200 is available to power other devices.
