What Is VEC-MIBv5-5?
VEC-MIBv5-5 is a vendor-specific MIB (revision 5.5) from Emerson Energy Systems North America (ESNA), part of the broader Emerson/Vertiv power systems line, used to manage DC power plant equipment such as rectifiers, battery strings, and load-distribution shunts. It is heavily trap-oriented, defining summary and per-node notification types for power-conversion units (PCUs) and current-shunt monitoring devices rather than a large set of polled data tables. It supports monitoring of power infrastructure hardware status — specifically rectifier/PCU health, battery/load shunt conditions, and system-level fault summaries that flag failing or degraded power modules in a telecom or data-center DC plant. As a proprietary Emerson/ESNA MIB it has no explicit stated dependency on other IETF MIBs but follows standard SNMPv2 trap conventions. It is typically deployed in telecom central offices and data centers on Emerson/Vertiv DC power plants and battery/rectifier cabinets, where the VEC-MIBv5-5 MIB supplies the trap definitions used for power-fault alerting.
IPNetwork Monitor allows you to monitor SNMP objects defined in VEC-MIBv5-5. 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
- Emerson/ESNA DC power plant rectifier systems
- battery/shunt distribution cabinets
- Emerson Network Power (now Vertiv) DC power plant systems monitored via the Vortex Ethernet Card (VEC) -- rectifier/PCU and battery/shunt distribution cabinets
Monitoring Examples
The MIB centers on trap notifications: psPCUSummaryTraps and psPCUTraps report rectifier/PCU-level state changes (e.g., failure or overtemperature) while psShuntTraps and psShuntSummaryTraps report current-shunt (load/battery distribution) alarms. An NMS subscribing to psPCUTraps would learn of an individual rectifier module failing, while psPCUSummaryTraps would indicate a system-wide power capacity shortfall; a technician would use these to prioritize replacing a failed rectifier before battery reserve is depleted.
What Can Be Monitored
- rectifier/PCU fault state
- PCU summary/system-wide power status
- shunt (load distribution) alarm state
- shunt summary status
