8-22 Broadmore 1750 - Release 4.6
Maintenance and Troubleshooting
Alarm Response/Reset
The failure recovery process is a logical sequence of events to restore connectivity.
With monitoring and corrective action at each step, the process includes:
Providing power to the Broadmore 1750 and control station
Establishing connectivity between the Broadmore 1750 and control station
Loading the Broadmore 1750 configuration
Establishing ATM connectivity
Establishing individual circuit connectivity
Alarm Response/Reset
Alarms are designed into the Broadmore 1750 to provide the initial indication of a
communications problem and to help isolate the problem. For example, a major alarm
from a SAM identifies the specific module that will focus response efforts. The
following flowchart approach to troubleshooting is based upon the initial alarm
indication. The alarm response is a three -step process:
1. Troubleshoot to isolate the cause.
2. Complete corrective action to eliminate the alarm condition.
3. Return system to full operation and document the events.
Alarms are designed as real-time alerts. Thus, elimination of the alarm condition will
automatically reset the associated alarm.
Flowchart
The top-level troubleshooting flowchart is shown on the below. LED indicators are the
basis for entry into the flowchart, which will lead to the most likely problem(s) and
recommended solution(s). The control system alarm indication can also be used as an
entry point. In either case, use of this flowchart provides a logical approach to
troubleshooting in the event that a problem is encountered.
