NB750 and DCE 7.8 error Device status may be inaccurate because an attempt to transfer a device definition file (DDF) failed

[masolans]

My DCE (ver 7.8) detect my new nb750 ( ver 5.2.2.63) but receive that error Device status may be inaccurate because an attempt to transfer a device definition file (DDF) failed

Credentials are correct, ports are open in the network

How can solve it?

Dear @masolans 

I have seen this error occurs for the two reasons mainly:

Using Netbotz 750 superuser account password instead of appliance's root account password in Device File Transfer Settings

Using the wrong protocol ie., FTP instead of SCP

Please also refer this k-base docs that can be useful for this DDF error.

https://www.apc.com/au/en/faqs/FA177004/

If possible, please verify these settings again and re-discover the Netbotz 750 appliance in DCE. Please also make sure that you are able to ping the Netbotz appliance IP address through DCE web UI --Status--Additional Information--Troubleshoot network--Ping. If this fails and if DCE can not ping the device, I recommend allowing ping on the device / network where applicable and see if it helps. 

I hope this helps. 

Regards,

Bala

I am also facing the same problem, as mentioned in the @masolans  statement, 

I have done the changes Root, and SCP settings etc. as per your reply but there is still the error persist,

I also upload the Updated DDF files from the https://ddf.ecostruxureit.com/

@mianaqeel 

please try to ping from DCE Server to Netbotz750 IP.

If its not pinging enable/allow "icmp" in your firewall from DCE Server IP to Netbotz750 IP. 

Hope this helps.

Thanks

Hi @mianaqeel May I know the firmware version of Netbotz 750? Is it 5.2.2 or 5.2.3? Are you trying to discover it first time on DCE? 

Note: The DDF file that you downloaded is different from scanner DDF. DDF needs to download the scanner DDF file from the device during the discovery process. If it fails, then DCE shows this error. 

If the issue still persists, then I suggest you to contact your regional CCC technical support team as they can guide you to resolve this issue. 

You can find the contacts in the below link:
