When attempting to upgrade the firmware in an MNB-1000, this error appears:
"Error 7 updating firmware--cannot start bootloader".
It appears like the MNB-1000 is running for a short period and then resetting.
TAC IA Series
I/A Series MNB 1000
On occasion, activity on the MSTP trunk will cause this error.
- Access the MNB-1000 and disable the MSTP trunk.
- Attempt to upgrade the Plant controller again.
Note: Use an IP connection to the MNB-1000 for the upgrade.
- Re-enable the MSTP trunk once the upgrade is complete.
