This trap is sent when the user configured settings for a VOADM would force the power levels to be outside of allowed operating ranges for the current link conditions. The source is a 4 or 5 tuple specifying the type, location, shelf, slot ID, and optionally the port number of the source of the event. In the case of the power supply and fan, the shelf number is set to 0. Each event has an unique event ID. It also has a preset event severity. The severity or trap type may be: critical, major, minor, or normal. For a given event severity, there is a corresponding system status, not necessarily the same as the event severity. For each reported trap, the IP address of the CP responsible for sending this trap is also included in the trap structure.
