I had several times the issue, that one PS of the C45-4200 type was in the following state:
PS2 PWR-C45-4200ACV AC 4200W err-disable good good
The problem is, that no SNMP trap was generated and so nothing was noticed unless someone used the show power command.
After reset the PS, a big bang occurs normally and then, of course, you have all the alarms you want...
Is this a design problem or how can one ensure PS redundancy?
Thanks and regards
