Dear Huawei,


I have S1720-28GWR-4X-E and after powering device sys is only fast blinking. Eth port did not become active and there is no way how to access device ( cli port is not present on this device ).


Is there any way how to rescue it?


I tried to hold reset, wait 10 minutes, hold it again. No result.


Thank you

Well, I think he means he waited for 10 minutes after reset the switch before restarting it.
@Tomiczech if the switch stucked in the fast blinking for a super long period, I think there might be some error with the firmware, also, as you said, S1720 doesn't get a console port, you might need to contact with the local TAC to get the switch repaired.

Hi Tomiczech
If the SYS indicator blinks fast, the system is starting. When the indicator blinks slowly, the system is running properly.

I hope it helps!

Hi @Tomiczech,
the fast blinking indicates the switch is starting, you are kindly advised to wait a second until the switch finishing the starting.

Maybe it is a good idea to try to reset it with the reset button?
