Bricked ZyXEL GS1900-24E after FW upgrade

Hi,

I have just upgraded the FW on my ZyXEL GS1900-24E from v. 2.20 to 2.30.

After the FW upgrade went through, the switch rebooted and since then the management web interface is not accessible anymore - neither using the custom IP from the configuration, nor the default 192.168.1.1.

However, the basic switching capabilities of the switch are present, and the devices connected to it are able to communicate over the network.

I have tried to reboot the switch again, also reseting the configuration using the tiny HW button did not make any change.

Is there anything else I can do to make my switch manageable again?

Thanks a lot!

    Hi,

    I have already managed to solve my problem.

    Seems with the new FW, the device started to get it's IP from the DHCP instead of using the default hardcoded one.

    I have installed the ZON Utility and used it to discover my device and found out it's still there, but listening on a different IP.

    Hi @pszabo,

    Welcome to Zyxel community!

    I am glad to hear that your problem is resolved by using ZON Utility.

    The root cause of your problem is that it is an original mechanism for GS1900 series:
    If the switch connect to a network which have a DHCP server in when rebooting from factory default, it will request for DHCP IP rather than using the default IP address 192.168.1.1. 

    This mechanism make the user can configure the switch faster after reseting the switch to default in a DHCP environment from remote site.

    I have also tried to reproduce your problem by the following procedure:
    1. Access GS1900-24E which is default configuration (IP address 192.168.1.1, firmware version V2.20).
    2. Change the IP address to 192.168.1.50.
    3. Firmware upgarde to V2.30 without saving the configuration, click "Yes" to reboot the switch after uploading the firmware.
    4. The IP address change to DHCP IP after reboot.
    I suspect that maybe you did't save the configuration before firmware upgrade.
    Please remember to save the configuration after changing some settings or before firmware upgrade.

    Hope it helps.

    You should try using ZON. It made managing their web smart switches so much easier. And best of all, it's free!
