3.6.9 Alarm Configuration
IMC-1000MS has an alarm relay with NO (normally open) and NC (normally closed) relay contacts which are available at the terminal block
on the top of the unit. When there is an alarm condition (the RED alarm LED is lit) the NC relay will be closed. When there is no alarm
condition (the RED alarm LED is off) the NO relay will be closed. If the device has no power, the NC relay will also be in a closed state (alarm
active).
The programming here of the alarm serves two functions. First, the alarm indication of LED and the relay state are controlled by fault
conditions of power, UTP link and/or Fiber link. Second, if SNMP is enabled, traps will be generated only on those alarm conditions that are
configured.
In the default configuration, all sources for alarm are enabled. Settings are applied immediately.
Example configuration:
An alarm will be triggered (and SNMP trap sent) only in the event of a loss of fiber link.
