What Is CTRON-POWER-SUPPLY-MIB?

CTRON-POWER-SUPPLY-MIB is a Cabletron (Ctron) private-enterprise MIB that monitors power supply units in Cabletron networking equipment, covering operational state, redundancy status, and fault conditions. It belongs to the hardware/environmental category of MIBs, focused specifically on power subsystem health rather than traffic or interface statistics. It is explicitly built for hardware status monitoring: tracking whether each power supply is present and operational, whether redundant supplies are providing failover coverage, and whether any fault (such as a failed or missing supply) has occurred, which are critical early-warning indicators for chassis-level outages. As a hardware-focused module it likely complements Cabletron's chassis/environment MIBs to give a complete picture of device health. It is typically deployed on Cabletron modular switches/routers with multiple power supply slots in enterprise or carrier network closets. Network engineers evaluating or troubleshooting this functionality can download the CTRON-POWER-SUPPLY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CTRON-POWER-SUPPLY-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

No object names were provided in the source excerpt, so a concrete polling walk cannot be grounded in named identifiers; based on the module description, an administrator would expect a power-supply status table reporting per-supply operational state, redundancy state, and fault flag, polled to detect a failed or removed power supply before the device loses redundancy. A supply reporting a fault or non-operational state while the device still has power would indicate the surviving supply is now a single point of failure.

What Can Be Monitored

power supply operational state
power supply redundancy status
power supply fault condition
