Description: HH3C MIB for redundant power supply management monitoring dual PSU status and failover on H3C chassis.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is HH3C-REDUNDANCY-POWER-MIB?
HH3C-REDUNDANCY-POWER-MIB is an H3C MIB for monitoring redundant power supply and fan modules in H3C chassis-based switches/routers. It exposes a power-supply table (hh3credundancyPowerTable) with per-unit ID, current status, and previous status, plus a parallel fan table (hh3credundancyFanTable) with per-fan ID and status, alongside dedicated trap groups for power and fan events. This is a core hardware-health monitoring MIB — its entire purpose is tracking power supply and cooling fan status so operators can detect a failed PSU in a redundant pair or a failed/degraded fan before the chassis overheats or loses power redundancy. It has no stated dependency on other MIBs in this excerpt, functioning as a self-contained hardware-status extension alongside H3C's broader system/chassis MIBs. It is deployed on H3C modular switches and routers equipped with redundant power supplies and fan trays in enterprise and data center environments. Network engineers evaluating or troubleshooting this functionality can download the HH3C-REDUNDANCY-POWER-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-REDUNDANCY-POWER-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.
Supported Devices
- H3C modular switch/router with redundant PSU and fan modules
Monitoring Examples
An operator would poll hh3credundancyPowerTable/hh3credundancyPowerEntry for hh3credundancyPowerID and hh3credundancyPowerStatus, comparing it against hh3credundancyPowerPreviousStatus to detect a PSU that has just transitioned from normal to failed. Similarly, hh3credundancyFanTable/hh3credundancyFanEntry with hh3credundancyFanID and hh3credundancyFanStatus would be polled to catch a failed fan module, and hh3cpowerTraps/hh3cfanTraps would fire notifications the moment such a state change occurs, letting an NMS alert on hardware redundancy loss in near real time.
What Can Be Monitored
- power supply unit status
- power supply previous status (state transition)
- fan module status
- power supply/fan failure trap notifications
