Issue
Following a clean upgrade from Continuum 1.74 to 1.93, all ACX78x controllers have the No Server LED illuminated.
Product Line
Andover Continuum
Environment
- ACX780
- ACX781
Cause
The SystemStatus system variable is set to No Database.
Additionally, the AccessServer system variable on the ACX78x controller is not correctly configured—it is not set to the ACCID of the primary access server workstation.
The No Server LED illuminates when the controller cannot establish a valid connection with the access server. This typically occurs due to misconfiguration of the AccessServer variable.
Resolution
To resolve the issue:
- Set the SystemStatus variable to Normal.
- Ensure the AccessServer variable is correctly configured:
- It must be set to 0 or to the controller’s own ACCID.
- Do not set it to the ACCID of a workstation or any other device.
Important Note
Setting the AccessServer to any value other than 0 or the controller’s own ACCID will trigger the No Server LED, indicating a failed server connection.
