IBM 46K4939 – POWER7 80mm Fan Assembly

The IBM 46K4939 is the 80mm fan assembly (also called fan FRU) for the IBM Power 780 (machine type 9179-MHB / 9179-MHC) and some configurations of the Power 770 (9117-MMB / 9117-MMC).

This is a hot-swappable, redundant cooling fan module that provides active airflow for the Central Electronics Complex (CEC) in these high-end POWER7 servers. It is a single 80mm high-speed fan housed in a plastic tray with a latch mechanism, designed to cool the processor books, memory DIMMs, and I/O components.

In the Power 780 (and multi-book Power 770), there are multiple fan assemblies (typically 6–8 depending on configuration) working together with N+1 redundancy. The system dynamically adjusts fan speed based on thermal sensors. If one fan fails, the remaining fans increase speed to compensate, and the system raises an alert via the HMC.

The IBM 01LJ126 is a hot-swap fan module (also listed as fan FRU or cooling module) designed specifically for the IBM Storwize V5000 Gen2 storage systems, particularly the 92F model (24-bay 2.5-inch SFF enclosure) and related expansion units in the V5000 Gen2 family.

This is a high-speed, redundant fan assembly that provides active cooling for the Storwize V5000 Gen2 controller enclosure or expansion enclosure (92F = 2.5" SFF 24-drive canister). The module contains multiple high-RPM fans arranged in a single replaceable tray, with integrated airflow direction optimized for front-to-back cooling in the enclosure.

Key characteristics:

• Hot-swappable design — can be replaced without powering down the enclosure when redundancy is maintained (N+1 fan redundancy typical in V5000 Gen2)
• Built-in fault detection and reporting to the Storwize firmware (via LED status and system alerts in GUI/CLI)
• Tool-less insertion/removal with latch mechanism
• Front-to-back airflow (cold aisle intake, hot aisle exhaust)
• Low acoustic noise profile for data center environments

Failure of a fan module typically triggers:

• Amber fault LED on the module
• Enclosure fault light
• Critical alert in Storwize GUI / CLI / email / SNMP
• Potential thermal throttling or enclosure shutdown if multiple fans fail

Replacement restores full cooling redundancy and prevents overheating of drives, controllers, or cache batteries.
