The Cisco ASR 907 Router power supplies are hot-swappable. If you have installed redundant power supply
modules, you can replace a single power supply without interrupting power to the router.
Note
To avoid erroneous failure messages, allow at least 2 minutes for the system to reinitialize after a power supply
has been removed or replaced.
Caution
When you install the unit, the ground connection must always be made first and disconnected last. Statement
