DNOS-BOXSERVICES-PRIVATE-MIB

Description: Monitors hardware box services including fans, temperatures, and power supplies on Dell DNOS switches.

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.

DNOS-BOXSERVICES-PRIVATE-MIB is a Broadcom-authored private MIB used within Dell's DNOS (Dell Network Operating System) switches to expose box-services, the physical chassis-level hardware subsystems such as fans, temperature sensors, and power supplies, per the module's short description, alongside detailed power usage history. It provides historical power-consumption sampling per unit (boxsUnitPwrUsageHistoryEntry) with a configurable sample interval and maximum sample count, plus per-sample timestamped power consumption readings and an aggregate stack-wide power consumption figure. This is squarely a hardware health MIB: it lets an admin track power draw trends over time per switch unit and across a stack, which combined with the broader box-services feature (fans/temperature/power supplies) gives visibility into thermal and power health of the chassis. As a private Broadcom/Dell MIB it is layered on top of the switch's standard ENTITY-MIB style hardware inventory, adding vendor-specific power-history telemetry. It is deployed on Dell EMC Networking switches running DNOS, particularly in stacked configurations where per-unit and stack-wide power budgeting matters. Engineers can download the DNOS-BOXSERVICES-PRIVATE-MIB file directly to load it into their MIB browser.

Polling boxsUnitPwrUsageHistoryEntry (indexed by boxsPwrUsageHistoryUnitIndex and boxsPwrUsageHistoryUnitSampleIndex) returns boxsPwrUsageHistoryUnitSampleTime and boxsPwrUsageHistoryUnitPowerConsumption, letting an admin graph a unit's power draw over the configured boxsPwrUsageHistoryUnitSampleInterval and spot an abnormal spike that might indicate a failing power supply or an over-provisioned PoE load. boxsPwrUsageHistoryStackPowerConsumption gives the aggregate figure across all stack members, useful for confirming the stack remains within its total power budget. A steadily climbing or erratic power consumption trend here would be an early sign of a hardware fault worth investigating before a fan or power-supply failure trap is raised.
