Outlet Status traps
Status Error Description
On Outlet is on
Off Outlet is off
OnWait Outlet Status in transition
OffWait Outlet Status in transition
OnError x Outlet should be off but current is sensed at the outlet
OffError x Outlet should be on but no current is sensed at the outlet
NoComm x Communication to the outlet has been lost
OffFuse x Outlet should be on but a blown fuse has been detected
Environmental Monitor Status traps
Status Error Description
Normal The Environmental Monitor is working correctly
NoComm x Communication to the Environmental Monitor has been lost
Temperature/Humidity Sensor Status traps
Status Error Description
Found The sensor has been detected
NotFound No sensor has been detected
Lost x Sensor initially detected but communication to the sensor has been lost
NoComm x Communication to the sensor has been lost
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 non-error status.
Load traps
Status Error Description
Normal Infeed is on and within preset thresholds
NotOn Infeed is off
Reading Non-error state – Load status currently being read
LoadHigh x Infeed current load exceeds preset threshold
OverLoad x Infeed current load exceeds the measurable range for the infeed
ReadError x Unable to read Load status
NoComm x Communication to the infeed has been lost
