Router 4331 is not working

Abdelrahman salah · ‎06-02-2022

Dear All,

I have an issue with router 4331. The router not appeared any output over CLi by SSH or console cable, and I sure the console cable is working fine

I used this cable with another device to check the cable and found everything was working fine. Plus,

The leds (Temp , Pwr , FAN and STAT ) at the router are flapping, and the flash led is not working.

How to solve it

- Possible hardware problem, can you power cycle -> is there still any output and or boot info's presented on the console ?

Hello,

I agree with @marce1000, this sounds like a hardware failure. How old is the device ? I remember there to be an issue with the internal hardware clock, which would cause the device to fail. Check if the field notice below applies:
