Sonicwall TZ400 Power light blinking after outage power

rmayoral · August 2021

Hello,

We have a Sonicwall TZ400 and after a power outage, the only light we get is a blinking light on the power led. Any idea what means?

Thanks,

@rmayoral check the power supply. I guess this is broken. to less power...

Hello @ThK

Thanks for your reply, we try with another power supply and the same result.

@rmayoral check if you can access the device on x0 with http://192.168.168.168

try to ping. maybe it is in save mode and has lost or broken the firmware

otherwise you should open a case

Hi @RMAYORAL,

Could you please let me know the color of the blinking power light?

Hello @Saravanan,

Thanks for your reply. The light is blue

Hi @RMAYORAL,

Thanks. Looks ODD.

Does the blue power light still blink continuously? Looks like power issues. Have you tried different power outlet by any chance?

Hi @Saravanan, yes we tried another outlet, still the same. It is not exactly continuous, turn on for 2 sec then turn off for 2 sec, like a power cycle.

Hi @rmayoral,

Thanks.

Since the issue started happening after a power outage, did the SonicWall installed environment have necessary power backup?
