7.7 ALARM REPORTING

Figure 7.25 Setup (Advanced)

Alarm Reporting

The ViPR radio can be enabled to report several different types of alarms using the SNMP

protocol. If SNMP is enabled (Setup (Advanced) – IP Services) and reporting is enabled for

a specific alarm, the ViPR will send an SNMP Trap to each of the IP addresses listed in the

Trap IP List (Setup (Advanced) – IP Services) whenever an alarm occurs.

If the condition that caused the alarm clears, the ViPR will send a second SNMP Trap to each

of the IP addresses listed in the Trap IP List, indicating that the error has cleared.

7.7.1 Forward Power Alarm & Notification

The Forward Power Alarm will trigger when the measured forward power drops 1 dB or more

below the user configured transmit power. The Forward Power Alarm SNMP trap is

generated when this condition occurs. When the forward power returns to within 0.8 dB of

the wanted power the error is cleared and a second notification is sent indicating the error

has cleared.

For example, assume the ViPR is programmed to transmit at 10W. If the measured forward

power drops below 7.9W then the error is detected and the SNMP Trap or Alarm is

generated. If the forward power then rises above 8.3W the error is cleared and a second

SNMP Trap or Notification is generated.

7.7.2 Reverse Power Alarm & Notification

The Reverse Power Alarm will warn the user of a major problem with the Power Amplifier or

Antenna, such as the antenna becoming disconnected. The alarm will trigger when the

measured reverse power increases to within 3 dB of the user configured transmit power.

The Reverse Power Alarm SNMP trap is generated when this condition occurs. When the

reverse power drops 5 dB below of the wanted power the error is cleared and a second

notification is sent indicating the error has cleared.

For example, assume the ViPR is programmed to transmit at 10W. If the measured reverse

power increases above 5.0W then the error is detected and the SNMP Trap or Alarm is

generated. If the reverse power then drops below 3.1W the error is cleared and a second

SNMP Trap or Notification is generated.
