Perfectly functional ICX7150 switch started rebooting since a week; every couple of minutes

Never had any issue for 2 years, and all of sudden since last Friday 17 July 2026, I noticed this switch rebooting after every couple of minutes / hours. So frustrating, that I don't have a stable connection. 

CLI log gave no clue, it does boot in to switch mode only. Works for a couple of minutes (~10 or 20 minutes) and then restarts. 

Currently this switch is connected to Xfinity's modem+router. 

Need help to resolve this issue quickly.

I hope, I'm not speaking too early - but it seems my switch may have had got impacted by power glitch followed by stuck in non-compliant mode. Following steps to switch to SDS mode may have helped - now that it's not rebooting as much (not in last 3 hours).

Update Next morning:

Yes, I was right about speaking too early.. The same reboot happened during night time too. Just that frequency reduced. What is wrong?
