MX10003 DC Power System Description
The MX10003 uses either AC or DC power supply modules (see
six power supplies located at the rear of the chassis in slots PSM0 through PSM5. 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. See
"MX10003 Component Redundancy" on page 23
on the AC and DC powered router. Each power supply is cooled by its own internal cooling system. The
chassis is designed to support N+N mode with feed redundancy, and N+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.
CAUTION:
NOTE: Routers configured with only one power supply are shipped with a blank panel installed
over the power supply slot that is not populated.

Do not mix AC and DC power supplies in the same chassis.
