Hardware Features Detailed Description
Alarm Port
Note Currently not supported. This hardware feature will be supported in a future software release.
Attach the alarm port (see Figure 3-13) to an alarm system to monitor events that occur in the router’s
physical installation environment (for example, indicating that the router door has been opened). The
port supports two alarm inputs and two alarm outputs.
The alarm-trigger setting determines when an alarm is sent to the attached alarm system.

• Open—The open setting indicates that the normal router operating condition has an electrical
current passing through the alarm circuits (DRY contact closed). If this electrical current is no
longer detected (DRY contact open), an alarm is generated.
