6.2.3 Alarm Masks
Each of the Major and Minor Alarms listed above can be ‘masked’ so that the alarm will not result in
an indication on the front panel LEDs or the ALARM connector. However, the alarm will be
displayed in any of the control modes (Remote, Terminal, or Front Panel). This feature is very
helpful during debugging or system testing to lock out a failure that the user is already aware of. The
alarm masks may be configured from the Front Panel, the Terminal Port, or the Remote Port.
6.2.4 Latched Alarms
Latched Alarms are used to identify intermittent failures in an RCS20 redundancy system. If an
alarm occurs, the alarm condition will be stored even if the condition causing the alarm ceases.
Latched alarms can be displayed and cleared from the Front Panel, the Terminal Port, or the
Remote Port. Note that latched alarms do not show any indication on the front panel LEDs or
ALARM connector. It is recommended that all current and latched alarms be cleared as a final step
after all modems and the RCS20 are configured and running.
