no power to APs after switch power cycle

[jjasensk]

hi All, I had a recent modem+router failure (unit is bricked an sent for RMA). in doing my own troubleshooting, I powercycled the switch and now is no longer sending power or data to any unit. Only PWR (green) and SYST (amber) are on and solid color. I tried reflashing the firmware via FTFP (instructions provided in another post), but continue in the instructions when unable to locate correct COM port number. Whenever USB is plugged in, device manager shows Ruckus switch as "CP2104 USB to UART Bridge Controller" under other devices. PuTTY is unable to connect to any COM ports (i tired COM1-4).
