Issue
An I/A Series R2 (Niagara) station opened in the Admin Tool displays "Disabled." What does this error message mean?
Product Line
TAC IA Series
Environment
An I/A Series R2 (Niagara) UNC.
Cause
When a station is in the disabled mode, it indicates that the station has rebooted multiple times in a five minute period. Possible causes are rapid fluctuations in the AC power supplying the UNC, a bad battery, or a station with less than 20% idle time.
Resolution
- Disconnect the battery, then cycle power to the UNC and see if it boots up normally.
- Run the system spy: in a browser, enter http:// (ipaddress of UNC):3011/system/spy.
Login with the hardware user name and password.
At the bottom of the page, click on "Reset Counter", then check to see if the idle time exceeds 20%.
If not, the station will need to be tuned to increase the idle time. - Check battery per Niagara R2/G3 UNC/JACE reboots every 15 minutes with "Battery test failed" logged. See Batteries for the UNC-410 and UNC-520 are interchangeable for battery part numbers.
