Dual Redundant Modular Power Supplies
Cisco Catalyst 3750-X Series and 3560-X Series Switches support dual redundant power supplies;
One power supply is shipped with the switch by default;
Other power supply/suppliers can be purchased when ordering the switch or next time according to your needs.
If only one power supply is installed, it should always be in the power supply bay 1.
Table below shows the different power supplies available in these switches and available PoE power.
