Currently my C3925 router is running on a single power supply.
we intend to get a 2nd PSU for redundany.
question, do I have to shutdown the router in order to install the 2nd PSU, or is it hot plug ?
there are video online showing how to add a 2nd PSU for C3845 router but not C3925.
how different are the installation?
i presume to be minimum since both are of the same range.
