C2G124 - 24 firmware - unable to boot

[DFH]

Hello guys,
I have a problem with C2G124-24 switch. It looks like it cant boot because all leds are on while CPU led is blinking green. I tried to connect to the switch via putty but nothing appeared (yes, I pressed enter/space). So I tried to download new firmware, and upload it directly on card storage of the switch, but switch is still not responding. Can you please help me with this switch? Thank you! 🙂

I'm pretty sure that cable doesn't work on that switch....or have you tried it on a working switch ?!

I've tried it with the same (instead of the Cisco I've a Huawei - both use the same pinout) but the XOS connector doesn't work with that model of switch.

I've a bunch of console cables/connectors for all different vendors and for a C-series I use the USB-DB9 and a DB9-DB9 Serial Null-modem Cable and that works fine.

I am connected to console this way, but I dont see anything. I have tried factory reset but it didnt respond.

Are you connected via the console port ?!
