During normal operations, software or firmware may detect error conditions pertaining to specific Maintenance Objects (MOs). The system automatically attempts to either fix or circumvent these problems. Errors are detected in two ways:
The technician can run periodic and scheduled tests on demand.
When an error is detected, the maintenance software puts the error in the Error Log and increments the error counter for that error. When an error counter is "active" (greater than 0), there is a maintenance record for the MO. If a hardware component incurs too many errors, an alarm is raised.
