I don't think there is an API to report alarms. It could be the software is corrupt or has issues booting, or hardware related. You could try and SSH into the codec and run "selectsw", and switch to a secondary software image and see if it would complete it's boot cycle.
Sorry, meant to be serial, not SSH.
If you're not able to access the CLI via serial (115200, N, 8, 1), you'll most likely have to open a TAC case and file an RMA. If you can access the CLI interface via serial, try the selectsw command, if that doesn't work, try factoryreset.
systemtools selectsw xCommand SystemUnit FacotryReset
I have tried the steps you told but no luck i believe i will have to go for RMA/TAC.
Can you please help me with my another discussion for DX80
I'd try to help with the DX80, but I don't have a background in CUCM, so I won't really be much help. Sorry.
Let us know what comes of the SX80 when you contact TAC.
I have the same problem exactly. LED flashing slowly, and nothing happens. Tried factory reset (hold power button 10 seconds and then press twice) but no effect. Still same issue. No video output on any of the monitors connected. Feels like a dead codec. It is out of warranty - checked. Is there any way to fix that? This is expensive device, why it died like a Chinese cheap electronics?
