3CDSG8 no valid image, help needed

3CDSG8 no valid image, help needed

3CDSG8 no valid image, help needed

After a recent powerfailure my 3CDSG8 switch doesn´t work anymore.
When I connect to the switch using serial connection all I get is this:

Booting ...
*** No valid image. Please load image via COM port.

There no mention on the 3com homepage on how to do this, and google didn´t help either. I´m having a little trouble logging into 3com support, so I thought I´d ask here in the forum.
I did manage to find a firmwarefile on 3com, but it seems that the switch must be operational to use the downloaded file.

Is anyone out there able to help me with this?

RE: 3CDSG8 no valid image, help needed

Did you check the troubleshooting section of the manual? If it is a firmware problem, talk to tech support. They will probably replace it. The 3CDSG8 must be a recent addition to the Office Connect group, so is the unit under warranty?


RE: 3CDSG8 no valid image, help needed

You´re quite right, the switch was bought in february and is still under warranty.
The manual offers no help regarding the error I currently have neither does 3com knowledgebase.
I know that for some other 3com products there is a serial-upgrade-utility (SUU) that you can use in the event of a failed upgrade or missing image, but apparently it´s not available for this particular switch.
I´ve registered the product with 3com, but I can´t figure out how to file a servicerequest via the homepage. I´ve send a RMA-request instead (still awaiting an email regarding this).

Still thank you very much for your input.


RE: 3CDSG8 no valid image, help needed

I would call them, try 800-949-6894. They will issue an RMA and instructions.

Let us know the results.


RE: 3CDSG8 no valid image, help needed

I just recieved a replacement switch through my RMA-request.
I haven´t gotten any explanation from 3com regarding how the switch lost it´s image. That would have been nice to  know in order to prevent it from happening again.
I guess the "case" is closed, and hope I don´t get any trouble with the new switch.

RE: 3CDSG8 no valid image, help needed

I believe you can save a copy of the configuration to your PC, that way you WILL have a copy that can be uploaded if needed.

Myself, I save copies of the switch config files that I program for that purpose as a backup.

Remember, you always move forward by backing up!
