What Is PAIRGAIN-DSLAM-CHASSIS-MIB?
PAIRGAIN-DSLAM-CHASSIS-MIB is a PairGain Technologies private MIB for managing the chassis of a DSLAM (Digital Subscriber Line Access Multiplexer), covering slot inventory, card/unit identification, and chassis-level environmental status. Its data categories include chassis type, power supply and fan status, and per-slot card configuration and versioning. It is strongly focused on monitoring hardware and software status: pgDSLAMChassisPsStatus and pgDSLAMChassisFanStatus directly report power supply and fan health, while per-slot objects report installed unit type, serial number, and hardware/firmware/software version levels. PAIRGAIN-DSLAM-CHASSIS-MIB SNMP monitoring is particularly valuable for catching chassis-level power and cooling faults before they cascade into service-affecting card failures. It is a self-contained vendor-private chassis MIB without heavy reliance on external standards MIBs beyond basic SNMP conventions. Deployment context is PairGain DSLAM chassis deployed in telco central offices and remote terminals for DSL broadband access.
IPNetwork Monitor allows you to monitor SNMP objects defined in PAIRGAIN-DSLAM-CHASSIS-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.
What Can Be Monitored
- chassis power supply status
- chassis fan/cooling status
- installed slot/card unit type and serial number
- per-slot hardware/firmware/software version
Supported Devices
- PairGain DSLAM chassis
Monitoring Examples
An operator would poll pgDSLAMChassisPsStatus and pgDSLAMChassisFanStatus to confirm chassis power and cooling are healthy, catching a failing fan or power supply before it causes a broader outage. pgDSLAMSlotConfigTable/pgDSLAMSlotConfigEntry (indexed by pgDSLAMSlotNumber) would be checked for pgDSLAMSlotUnitType and pgDSLAMSlotUnitSerialNo to inventory installed line cards, and pgDSLAMSlotHwVer/pgDSLAMSlotFwVer/pgDSLAMSlotSwVer would be compared across slots to spot a card running outdated firmware or software needing an upgrade.
