Ruckus ICX 7150 - reset not working

[bbatjargal11]

Internet is working fine.

Switch is PWR and SYS lights on but ports do not.

All access points including Ring door bell is not working/ no lights on.

This issue happening after power outage - need help. 

Followed below link instruction - but when trying to telnet through PUTTY using serial number - cannot find COM number from Device Manager. PC shows only (Network adapter - realtek USBGbE Family Controller). Ethernet connection got established through Realtek USB GbE Family Controller - not Intel R Active Management technology. Need help.
