ARUBAWIRED-FANTRAY-MIB

Description: Aruba wired switch ArubaOS-CX fan tray presence, orientation, and status management.

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.

ARUBAWIRED-FANTRAY-MIB is an HPE Aruba proprietary MIB for ArubaOS-CX wired switches, focused on fan tray hardware management. It exposes environmental hardware data such as fan tray presence, physical location (group/slot index), name, product name, serial number, count of fans per tray, and operational state, along with a notifications group. This is squarely a hardware-health monitoring MIB: fan tray state and fan count are used to detect cooling failures before they lead to thermal throttling or shutdown of the switch. It is a vendor-proprietary companion to other ArubaOS-CX MIBs (such as the system-info MIB) rather than a standards-based module, so it depends on Aruba's own conformance and notification conventions. It is typically deployed on Aruba CX switches in enterprise wiring closets and data centers, polled continuously by monitoring systems for chassis-health dashboards. Network engineers evaluating or troubleshooting this functionality can download the ARUBAWIRED-FANTRAY-MIB file directly to load it into their MIB browser.

An admin walks arubaWiredFanTrayTable/arubaWiredFanTrayEntry keyed by arubaWiredFanTrayGroupIndex and arubaWiredFanTraySlotIndex to read arubaWiredFanTrayState and arubaWiredFanTrayNumberFans for each tray named via arubaWiredFanTrayName. If arubaWiredFanTrayState shifts away from normal, or the reported fan count drops below the tray's expected total, that signals a failed or removed fan tray requiring replacement to avoid overheating. arubaWiredFanTrayProductName and arubaWiredFanTraySerialNumber support asset tracking for RMA, while arubaWiredFanTrayNotifications can push a trap the moment a fault occurs.

Manages fan tray subsystems and monitors fan health status with notifications for insertion, removal, and fault conditions.
