2520G-8-PoE hangs after firmware upgrade

Hi,

I did a firmware upgrade to J.15.09.0025. but now, the switch hangs in the boot rom. Is it possible to change the firmware like on the 5400zl or download another from a xmodem or tftp server? And how can I do this?

 

thanks in advice

 

Stephan

Re: 2520G-8-PoE hangs after firmware upgrade

I found the solution for my problem:

1. disconnect power

2. press clear button

3. connect power and hold the clear button

4. wait about 10 seconds

5. release the clear button

6. you are in the rom console

7. change the boot image
