Description: Monitors Valere Power DC power system parameters including voltage, current, alarms, and rectifier status.

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 VPWR-DC-POWER-MIB?

VPWR-DC-POWER-MIB is Valere Power's enterprise MIB for its DC power system controllers, covering voltage, current, alarm, and rectifier status for telecom/networking DC power plants. The sample data available centers on a trap message-string object, indicating the MIB's primary runtime signal is alarm/fault notifications describing power-system events in human-readable text, alongside the broader voltage/current/rectifier status objects described in its short description. This makes it a hardware-status monitoring MIB at its core, detecting rectifier faults, abnormal bus voltage/current, and battery-related alarms that could foreshadow a power outage at a site. As a Valere-proprietary module it has no dependency on IETF standard MIBs, aside from standard SNMP trap conventions, and its revision history shows it evolved (e.g., renaming vpwrTrapDestinationTable to vpwrTrapTable) to fix compiler compatibility issues. It's deployed on Valere Power DC power plants at telecom central offices and cell sites. Engineers can download the VPWR-DC-POWER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in VPWR-DC-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

Valere Power DC power plant / rectifier system

Monitoring Examples

A monitoring system would trap on vpwrTrapsMsgString to receive a descriptive alarm message whenever the DC power plant detects a fault condition, such as a rectifier failure or out-of-range bus voltage. Because only the trap message object is available in the sample data, a full deployment would pair this trap with polling of the underlying voltage/current/alarm tables described in the module's short description to identify exactly which rectifier or alarm point triggered. The Ver 2.0 revision history shows a SysAlarm Config Table was added, suggesting configurable alarm thresholds are also part of the MIB.

What Can Be Monitored

DC power system alarm/trap messages
rectifier status
bus voltage and current
battery/alarm conditions

How to Use in IPNetwork Monitor

Example using vpwrAlarmsPresent OID:

Select a Valere Power DC power plant / rectifier system (voltage/current/rectifier alarm status) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type vpwrAlarmsPresent into the Find box to locate it in the OID tree, then select it and click OK. The present number of active alarm conditions. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
