I have a question as regards the distribution of Power supply modules on a M320 router. We have a M320 with 4 PEMs installed. One of the power supplies went bad (still investigating why) but at about the same time, the backup RE, CB1 and SIB1 went offline.
I want to know if this could be as a result of having 3 PEMs rather than 2 or 4 at a time? Or does anyone think that it cannot be related to power issues.
