Console shows unrecognizable characters due to a faulty port
Applies to
- All AFF systems
- All ASA systems
- All FAS systems
- Console connection
- All ONTAP versions
Issue
- login to console via serial console port and console does not respond to what is being typed and shows unrecognizable characters.
- The issue remains after console cable replacement.
- Use the same PC and the same method to connect the other node from the serial console port and no issue observered.
The following KBs were reviewed and determined not to be the cause:
- AFF / FAS platforms- Garbage characters are printed on the console when using Micro USB console connection
- Console cable only attached to the node or unconfigured may cause health alerts, prevent SP access and prevent failover
- Illegible characters displayed on console during boot in AFF and FAS series
