- Pulled from working environment. The IBM Flex System Fan Logic Module (FRU/Part Number 49Y3325, also associated with Part 94Y5805) is a dedicated cooling-control board that routes power and data signals to the cooling fans within an IBM/Lenovo Flex System Enterprise Chassis. It acts as a fan multiplexer (MUX) and logic pass-through for reliable 24/7 chassis airflow.Key Features and Functions
Chassis Management Integration: Serves as the localized routing layer between the chassis management modules and the physical fan modules.
Redundancy & Hot-Swapping: Supports the chassis' N+1 or N+N redundant cooling architectures, routing signals dynamically so that individual fan units can be safely replaced while the server chassis remains fully operational.
Thermal Regulation: Helps manage the chassis' cooling zones, coordinating fan speeds based on node power draw and configuration.
Field-Replaceable Unit (FRU): Designed for quick, tool-less serviceability and maintenance.
