What Is EQUIPMENT-MIB?

EQUIPMENT-MIB is a D-Link proprietary equipment-management MIB that models the physical hardware components of D-Link switch chassis, providing chassis, fan, power supply, stacking, and port hardware status objects. It exposes categories of data organized around physical hardware subsystems: chassis identification and slot layout, fan tray presence and operational state, power supply presence and status, stacking-unit membership/role, and per-port hardware status indicators. Its monitoring use is squarely in hardware status: administrators use it to detect a failed or removed power supply, a stopped or faulted fan, a stacking unit that has dropped out of the stack, or a port reporting a hardware fault, all of which threaten switch availability if left unnoticed. No sample objects or explicit companion-MIB references were available in the source material, so it likely depends only on baseline SNMPv2-SMI conventions while operating alongside other D-Link proprietary system and port MIBs for complete device visibility. Administrators typically load EQUIPMENT-MIB into a MIB Browser to explore its chassis, fan, power-supply, and stacking object tree before scripting automated hardware-health polling on D-Link switch deployments.

IPNetwork Monitor allows you to monitor SNMP objects defined in EQUIPMENT-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.

What Can Be Monitored

  • chassis/slot status
  • fan tray status
  • power supply presence and status
  • stacking unit membership/role
  • port hardware status

Supported Devices

  • D-Link DXS-3410-32XY (2024) — 10G Layer 3 stackable managed switch, D-Link's newest stackable line
  • D-Link DGS-1520-28 — Layer 3 stackable smart managed switch, current generation

Monitoring Examples

No sample object or table names were available for this module, so specific OIDs cannot be cited here. Based on its stated purpose, an administrator would poll this MIB's power supply and fan status objects to detect a failed or missing power supply or a stalled fan, and would check stacking-unit and port hardware status objects to confirm every unit in a stack and its ports are reporting hardware-healthy. A power supply or fan object transitioning to a fault state, or a stacking unit dropping out of the stack table, would be the key alarm condition this MIB is designed to surface.

FAQ

What is EQUIPMENT-MIB used for in a D-Link switch monitoring setup?
It's a D-Link proprietary MIB modeling the physical hardware of a switch chassis -- chassis/slot layout, fan tray presence and state, power supply presence/status, stacking-unit membership/role, and per-port hardware status. An admin uses it to detect a failed or removed power supply, a stopped or faulted fan, a stacking unit that dropped out of the stack, or a port reporting a hardware fault -- all of which threaten switch availability if unnoticed.

How do administrators typically start working with EQUIPMENT-MIB?
Since no companion-MIB references are documented, administrators typically load EQUIPMENT-MIB into a MIB browser to explore its chassis, fan, power-supply, and stacking object tree before scripting automated hardware-health polling across D-Link stackable switch deployments.
