CM : Major Power alarms (POW-SUP) for G650 655A power supplies caused by Router issues at the main site and an old TN2215 analogue card in the G650.

POW-SUP Major alarms several times a day. I found there were always sanity errors in the logfile before the POW-MAJ occurred. Sanity errors always count until 15 and right after the 15th sanity error the POW-SUP Major alarm occured. So we were concentrating on the network and the customer found a router issue at the Main site connecting to the remote G650. After this had been fixed, we found that there occurred only one MAJ-POW alarm during the maintenance routine each night. So we found the TN2215 with Vintage 15 and PSN001380u which state that Hardware Vintage 18 or higher is needed or a replacement with a TN793 analogue board would solve the issue. When checking the compatibility matrix you won’t find the TN2215 anymore at all. ;
