What Is OCCAM-SENSOR-MIB?

OCCAM-SENSOR-MIB (module_desc: "used to monitor the values of Sensors in the BLC1100") is a vendor MIB from Occam Networks for monitoring environmental sensors -- notably temperature and voltage -- on their DSL broadband loop carrier shelf equipment, specifically the BLC1100 platform. Although no object names are provided in this batch (sample_objects is empty), the description indicates the module exposes entity-style sensor readings tied to physical sensor instances within the shelf. Its purpose is squarely hardware environmental monitoring: tracking whether temperature and voltage sensors on the BLC1100 chassis remain within safe operating bounds, which is critical for detecting cooling failures or power supply irregularities before they cause service-affecting hardware faults. Given the "OCCAM-ENTITY-SENSOR-MIB" naming mentioned in its description, it likely follows the structure of the IETF ENTITY-SENSOR-MIB, associating sensor readings with entPhysicalTable entries. It is deployed by telecom operators running Occam Networks BLC1100 DSL access shelves in outside-plant or central-office broadband deployments, usually starting with an OCCAM-SENSOR-MIB download to load the module into their monitoring platform.

IPNetwork Monitor allows you to monitor SNMP objects defined in OCCAM-SENSOR-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An operator would poll the sensor value and sensor type objects (following the ENTITY-SENSOR-MIB pattern) for each physical sensor instance in the BLC1100 chassis to track temperature and voltage readings over time. A temperature reading climbing outside its normal range would indicate a cooling fan failure or excessive ambient heat in the cabinet housing the shelf, while an abnormal voltage reading could indicate a failing power supply. Because no specific object names were available for this module, this description is based on its stated purpose rather than concrete table/object names.

SEN sensorType	1.3.6.1.4.1.6066.2.1.3.2.1.1.1.1.3	SensorDataType	read-only	This variable indicates the type of data reported by the sensorValue. This variable is set by the agent at start-up and the value does not change during operation.
SEN sensorValue	1.3.6.1.4.1.6066.2.1.3.2.1.1.1.1.4	SensorValue	read-only	This variable reports the most recent measurement seen by the Sensor. To correctly display or interpret this variable's value, you must also know sensorType, sensorScale, and sensorPrecision. However, you can compare sensorValue with the threshold values given in sensorThresholdTable without any semantic knowledge.
