Chapter 5 Replacing Cisco ASR 9001 Router Components
Removing and Replacing AC or DC Power System Components
Power Module Replacement Guidelines
The Cisco ASR 9000 Series Router support online insertion and removal (OIR) for 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 soon as possible. Make sure you have the replacement power module ready before beginning the removal and installation procedure.
