Installation Guidelines
The Cisco XR 12410 router supports online insertion and removal (OIR). If you are replacing a redundant power supply, you can remove and install the power supply while the system remains powered on without causing an electrical hazard or damage to the system. This feature enables you replace a power supply while the system maintains all routing information and ensures session preservation.
However, to maintain operational redundancy, proper cooling, and meet EMI compliance standards, you must have both working power supplies installed. When you remove a failed power supply with the router in operation, perform the replacement as quickly as possible. Before you begin the removal and installation procedure, make sure you have the tools and the replacement power supply ready.
Caution You cannot mix power supply types within the chassis. If you are replacing a 2400 W power supply from an older system with a newer 2800 W power supply, you must replace both power supplies and the PDUs. You must shut down the router to perform the upgrade. Be sure to notify the appropriate personnel that all routing traffic stops while the upgrade takes place.
