The MX10003 uses either AC or DC power supply modules. The router contain six power supplies located at the rear of the chassis in slotsPSM0throughPSM5. The AC or DC power supplies directly plug into the midplane and are placed symmetrically on both sides of the chassis for better thermal management. Each power supply has a handle, an ejection lever, and a status LED. The power supplies connect to the baseboard, which distributes the different output voltages produced by the power supplies to the router components, depending on their voltage requirements. A minimum of 3 power supplies are required for non-redundant operation. If one power supply in a redundant configuration fails or is removed, the remaining power supplies assume the entire electrical load without interruption. Each power supply is cooled by its own internal cooling system. The chassis is designed to supportN+Nmode with feed redundancy, andN+1 mode without feed redundancy.

Redundant power supplies are hot-removable and hot-insertable. When you remove a power supply from a router that uses only one power supply, the router might shut down depending on your configuration.
