1 Critical Alarm Present - Lost the local network management interface-to-UPS communication.

[Edsonrdz]

Good morning, I have an SMX3000 UPS and I installed an NMC3 monitoring card. It was installed and configured correctly. I then downloaded the Secure NMC System Tool application and updated the firmware. After this update, I received the following error: 1 Critical Alarm Present - Lost the local network management interface-to-UPS communication. I have read other forums and tried the solutions.

restart the module from the web, from telnet, physically removing the card for a few seconds, resetting the card to factory settings the alarm is removed but after one or two minutes it appears again. I have noticed that the network configuration option no longer appears on the UPS screen, obviously because it has no communication with the card, I do not know what other solution I could try, what I think is that the firmware update was the cause and I do not know how to return to the previous version, it should be noted that after this alarm the secure NMC system tool software also has no communication with the card, I deleted it from this application and tried to add it again but it no longer locates it.

I'd like the NMC3 card to work properly and not always have this alert. If you could give me some guidance on how to resolve this, I'd really appreciate it.
I'm leaving you some information about the NMC3 card in case you need it. Thank you in advance.

I suggest you contact APC Technical Support if the NMC 3 is under warranty to track and help resolve this issue.

If the NMC 3 is not under warranty than you may refer to this APC Resource Link:
