Hi Jan,

 

I've had it happen back in the day where the AOM or SCCP serial connection wouldn't work after a while. Since you've verified all the settings, I'd try resetting it and see if it comes back. This command might work on that platform depending on software version:

 

ipmiutil reset -k

 

You might be able to just do an "ssh aom" from the CLI depending on version as well and reset it from there. If not, you might have to reboot or power off/unplug the whole device to get the AOM to reset.

Hello Dave, thank you for the answer, however it will take a while for me to verify this due to processes I have to follow..

 

Can you please clarify what exactly happens with the ipmiutil reset -k command and/or why is better then regular reboot?

 

BR, Jan
