[j-nsp] SSB Input power error

[Jonas Frey]

Hello,

most likely the power problem is not related to the SSB crash. You might
be hitting the "bad" powersupply problem with M20 AC powersupplys. Make
sure (via show chassis hardware) that you are *not* using one of the
following:
M20 AC PWR-M20-AC-S 740-001465 Revision 7 and earlier 
M20 DC PWR-M20-DC-S 740-001466 Revision 8 and earlier 

because they include buggy fan sensing/controlling.

Regarding the SSB problem: Check if you have any coredumps:
file list detail /var/tmp/*core*
file list detail /var/crash/*core*

If you have, submit them to JTAC for analysis.

Regards,
Jonas
