Eaton EMP MIB
Objects in this group are provided by the Environmental Monitoring Probe (EMP) and include temperature and
humidity readings, alarming limits, the two contacts readings, and setup information. The group contains a table
of values for environmental contact sensing (normally two digital inputs for monitoring all contacts).
Traps are sent in response to EMP changes to indicate the type of alarm, alarm acknowledgement, and alarm
clearing.
Eaton Alarms+Traps MIB
Objects in this group provide a table of active alarms and a count of alarms currently active. The notification
traps provided are triggered by the publishing of an alarm or event.
Eaton OID Assignments
These objects document all the object identifier assignments for Eaton products.
Entity MIB Files
The objects in these MIB files provide information standard in the industry:
l
The RFC 4133 Entity MIB provides standard objects for identifying and describing devices attached to the
card.
l
The RFC 4268 Entity State MIB provides availability status measures for each device.
l
The RFC 4268 Entity State MIB Part 2 provides possible state values for the Entity State MIB.
Selecting the UPS Trap Type

configured trapsinks when UPS alarms occur or clear. There are three types of traps: stnd(1), xups(2), and
pxg(5). See Table 7 for trap comparison.
