SNMP Traps
Status Trap
A Status trap is generated when an error condition occurs on a tower, infeed, Environmental Monitor or individual
sensor. Status traps include the reported status; location of the unit; identifier and name of the affected tower, infeed,
outlet, environmental monitor, and 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.

1
1
= The ENV part of the sensor supports two Temperature/Humidity (T/H) probes as part of the master unit, two T/H
probes as part of the link unit, and the optional EMCU-1-1 (which can support two T/H probes, four contact-closure
monitoring points, and one water sensor). The “No Comm” sensor status is not loss of communication with probes
themselves.
NOTE:
Traps are generated according to a hierarchy; for example, 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.
