RuggedCom RS400 manual Active Alarms, Passive Alarms, Alarms and the Critical Failure Relay, Level

Diagnostics

12.1.1 Active Alarms

Active alarms are ongoing. They signify states of operation that are not in accordance with normal operation. Examples of active alarms include links that should be up but are not or error rates that are continuously exceeding a certain threshold.

Active alarms are removed (cleared) either by solving the original cause of the alarm or by explicitly clearing the alarm itself.

12.1.2 Passive Alarms

Passive alarms are historic in nature. They signify events that represented abnormal conditions in the past, and do not affect the current operational status. Examples of passive alarms include authentication failures or error rates that temporarily exceeded a certain threshold.

Passive alarms are cleared through Clear Alarms option under diagnostics menu. RMON generated alarms are passive.

12.1.3 Alarms and the Critical Failure Relay

All active alarms will immediately de-energize the critical fail relay (thus signifying a problem). The relay will be re-energized when the last outstanding active alarm is cleared.

Note: Alarms are volatile in nature. All alarms (active and passive) are cleared at startup.

12.1.4 Viewing and Clearing Alarms

Alarms are displayed in the order in which they occurred, even if the real time clock was incorrect at the time of the alarm.
