Description: APC/Schneider modular power distribution unit outlet control, metering, and environmental 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 APNL-MODULAR-PDU-MIB?

APNL-MODULAR-PDU-MIB is a vendor MIB (AP Nederland, part of the APC/Schneider Electric product family) for modular rack-mount Power Distribution Units used in data center and network equipment racks. It exposes device identification data (product ID, serial number) alongside real-time power metering across the PDU's phases, including active power, reactive power (KVAR), and overall unit status. This is a hardware health and environmental monitoring module: pduStatus reports the operational state of the PDU itself, while per-phase power readings let operators detect overload conditions, phase imbalance, or a failing power feed before it causes an outage. It is a self-contained vendor extension without strong dependency on other IETF MIBs, focused purely on power infrastructure telemetry. It is typically deployed in data center racks to monitor the health and load of the power distribution feeding networking and server equipment. Engineers can download the APNL-MODULAR-PDU-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in APNL-MODULAR-PDU-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

APC/Schneider Electric modular Power Distribution Unit (PDU)

Monitoring Examples

An operator would poll pduStatus to confirm overall PDU health, and read pduPower alongside per-phase pduPowerL1, pduPowerL2, and pduPowerL3 to check for load imbalance across circuits. The pduKvar, pduKvarL1, pduKvarL2, and pduKvarL3 objects expose reactive power per phase, useful for detecting inefficient loads. A sudden drop in pduPower on one phase while others remain stable would indicate a tripped breaker or failed input feed on that leg.

What Can Be Monitored

PDU operational status
total power draw
per-phase power (L1/L2/L3)
per-phase reactive power (KVAR)
PDU serial number/product identity
