NOTE: Traps are generated according to a hierarchical architecture; i.e. if a Tower Status enters a trap condition, only the Tower Status trap is generated. Infeed and Outlet Status traps are suppressed until the Tower Status returns to Normal.
Change trap
The Change trap is generated for all outlet status changes between any on/off conditions. Change traps include the outlet status, Location of the Switched PDU, and identifier and name of the affected outlet. For descriptions of the outlet status types, please refer to the prior table.
Load Trap
The Load trap is generated whenever the total input load on an infeed exceeds a preset threshold. Load traps include the reported input load, load status, Location of the Switched PDU, and identifier and name of the affected infeed.
Any error state generates a Load trap and triggers the trap timer. A new trap is generated at the end of every timer period until the Load returns to a
