Hello everyone,
I have an issue with my APC by Schneider Electric AP8953 PDU. After logging in via Telnet, I can see that the system is running AOS version 6.5.6, but the Application Module shows the error:
css
Copiar
Editar
Invalid Module Header!
Because of this, I cannot access the web interface, and I am unable to enable SSH or SCP. I tried updating the firmware via FTP and Telnet, but it seems impossible because the Application Module is corrupted.
Hereβs what I have tried so far:
Logged in via Telnet and checked system status (about command)
Attempted to enable SSH via Telnet (no command available)
Tried accessing the web interface (not working)
Tried updating the firmware via FTP (not possible, SCP not available)
Does anyone have a solution or workaround for this issue?
