Cause
This issue occurs when the login page web files are not properly updated during the firmware upgrade. Specifically, upgrading SP-C-WEB controllers from pre-cybersecurity firmware versions (4.00.1505 or earlier) directly to version 4.00.2402 or later can result in missing login fields.
Resolution
Recommended Upgrade Path
This issue has been addressed in version 4.00.2510. SP-C-WEB controllers can now be upgraded from 4.00.359 directly to 4.00.2510 or higher, eliminating the need for the previous staged upgrade approach.
- Upgrade to 4.00.359, if not already on that version
- Upgrade to 4.00.2510, or higher
This ensures all necessary web files are correctly updated.
If the Issue Has Already Occurred
If you've already upgraded to a version between 4.00.2402 and 4.00.2510 and cannot access the login page:
- A workaround is available.
- Please raise a Product Support case.
- Support will assist you via a remote session to restore access.
