The
Cisco
Catalyst 3750-X Series and Cisco 3560-X Switches support dual redundant power supplies. The
switch ships with one power supply by default and the second power supply can
be purchased at the time of ordering the switch or at a later time. If only one
power supply is installed, it should always be in the power supply bay 1. (See
below figure).

In addition to the above power supplies a 440W DC
power supply is available as a spare (should be ordered separately) on all
switch models. The DC power supply also delivers PoE capabilities for maximum
flexibility, and customers can mix and match the AC and DC power supplies in
the two available power supply slots. Any of these power supplies can be
installed in any of the switches.
