SNMP Traps 
The Sentry supports three types of SNMP traps.  Traps are enabled at the tower (T), infeed (I) or outlet 
(O) level.

All traps include the Location of the Sentry as defined with the Set Location command.  
Status trap 
A Status trap is generated when an error condition occurs on a tower, infeeed, Environmental Monitor 
or individual sensor.  Status traps include the reported Status, the Location of the Sentry and identifier 
and name of the affected tower, infeed, outlet, environmental monitor or sensor. 
Any error state generates a Status trap and triggers the trap timer.  A new trap is generated at the end of 
every timer period until the Status returns to a non-error status.  All status traps are enabled by default.

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 Sentry, and identifier and name of the affected outlet.  For 
descriptions of the outlet status types, please refer to the prior table.
