Issue:
When logging into the web interface of a Network Management Card (NMC), the user is presented with an error message that the "Application is incompatible with this APC AOS"
Product:
All products that use a standalone or embedded NMC, including but not limited to UPS, Rack PDU, and ATS systems.
Environment:
All firmware and serial ranges
Solution:
An incompatible AOS error message can be caused by a number of factors, including but not limited to:
Where "A!" means there is an issue with the firmware application on the NMC. To resolve this, users should first try and reflash with the latest firmware version they have access to. If that does not resolve the problem, the next step would be to format the NMC by holding down the NMC pin reset button for 30 seconds (this will wipe all configuration from the card), and if the card is still inaccessible or unable to be given an IP address then upgrade the NMC using the "bootmonitor" method outlined in this article: Video: Using Network Management Card 2 (NMC2) bootmonitor to recover/upgrade firmware
