I am just looking for a clue to switch back the active image to the good one, but I don't have a chance cause it is an intermediate image from a software upgrade and there is no possibility in the CLI because of the continuous reboots.

Thanks for help.

Hi Andreas,


Even though I am using my SGE2000 as an example i don't think it is different to the SFE2000.


I started hyperterminal  at 115200baud  as per the setup guide.


from hyperterminal I tried the following, rebooted my SGE2000 and return when it asked me to.


I then had a option to download software via Xmodem.

Enter your choice or press 'ESC' to exit:

If that fails to fix the unit then just call the small business support center via the following URL;

Thanks a lot Dave it worked,



While I had my Laptop attached via serial to the device I had seen tis 2 second message


during the reboot cycles and Ionce entered this menu. But I didn't dare to do it. So in ther


meantime I rang the American support hotline and the guy gave me the advice to push the rest


button and power cycle the switch. And when I don't get a stable GUI I should forget the


device and get a new one. This didn't work, so with Your experience I thought this could be


the only chance. I had to press the reset button again and disconnect it from the rest of


the stack (4 devices) cause in the first place the upload via xmodem aborted. It worked on


the other devices as well even though very slowly despite 115200 speed. After connecting the


devices the stack built up again and I could update the firmware and bootloader on all


devices and all images; and it is still working. Just the old config file doesn't seem to


load without errors so there is still a little bit of handwork to do.



Thank You very much again and have a nice weekend.



Andreas
