PA Power Alarm & Notification
The PA Power Alarm & Notification will warn the user when the power amplifier goes into
either a Foldback or Shutdown State. The power amplifier will first go into the Foldback
state if the PA temperature gets too hot. In the foldback state, the Viper will cut the
transmit power in half every 4 minutes until the PA has cooled off. The transmit power will
not be reduced further if the power is originally set for 1W or reaches 1W due to foldback.
If the temperature continues to increase, the PA may go into Shutdown mode. If this
happens, another SNMP trap will be generated, indicating that the PA is Shutdown. The
Viper will not transmit until the unit cools down. This trap will not be sent over the air and
will only be sent out the Ethernet interface.
When the temperature drops back to a safe level, the Viper will resume transmitting at full
power and the PA Power Notification SNMP Trap will be generated to indicate that the Viper
is operating at full power again.
