NAC 3310- cannot connect to with serial connection

Unanswered Question
Apr 27th, 2010

I have (2) 3310 NAC appliances that someone else set up and configured. I need to access via a serial connection to my laptop to upgrade the software. I cannot connect via Hyperterm. I have 4 other NAC appliances that I can connect to fine via direct laptop serial connection. My hyperterm settings are correct. Log files do not show anything that could be causing this (per TAC). I can access via ssh over the network, and through the web gui.

I have this problem too.

Glad to hear that. So that someone else might also benefit from the resolution, perhaps you wouldn't mind posting it here too?

Short description is, I serial connected to the CAS's to do

a software upgrade, and could not get a connection to either of them. Through troubleshooting it seemed there were other issues going on with the Active CAS. Once I rebuilt (re-installed software) and reconfigured the HA pair, I was able to serial connect to both and then proceed with the upgrade.
