See KB article Dell Unity: Centralized ESRS registration failure Error Code 0x6400b76 for the same Error Code 0x6400b76 (But for different issues). (Dell Support login may be required to view this article)
When trying to add the Unity using Servicelink website, it shows an error: "Error occurred while attempting to validate the site id." (Adding Unity on Servicelink is for test only).
Cause
This is due to the site ID setting issue.
Check the ESRS site ID information per following link by the serial number "CKMuuuuuuuuuuu."

We have found there are two site IDs linked, and the status are NOT "INSTALL."
Resolution
We must engage the account team or Install Base team to correct it.
The requirement is to keep only one site ID which is linked to the Unity and the status should be "INSTALL."
