Removing and Replacing Power System Components

The Cisco ASR 9000 Series Routers support OIR of power modules. If you are replacing a redundant
power module, you can remove and install the power module while the system remains powered on
without causing an electrical hazard or damage to the system. This feature enables you to replace a power
module while the system maintains all routing information and ensures session preservation.
However, to maintain operational redundancy and proper cooling, and to meet EMI compliance
standards, you must have at least one working power module installed (more than one for a fully
configured system). When you remove a failed power module with the router in operation, perform the
replacement as quickly as possible. Make sure you have the replacement power module ready before
beginning the removal and installation procedure.
For the RSP/RP to communicate properly to a power module in a power tray, input power to at least one

of the three power modules in the power tray should be present.
