Hi all!
We have ASR903 routers with A900-PWR550-D power modules. Now as power consumption will be increased because of installing additinal line cards, we need to migrate on A900-PWR1200-D power supplies.
The question is, can we hot swap one of the 550W PS, install new one 1200W PS and then make the same with the second PS? Or we need to power off the router and then replase both PS ? I can't find answer for this in any cisco guides...
