HPE P49956-001 – Server Chassis Fan Module

HPE P49956-001 Server Chassis Fan Module

Overview

HPE P49956-001 is an enterprise hot-plug chassis fan module used in HPE ProLiant DL380 Gen11 rack servers. It is designed to maintain continuous and controlled airflow inside the 2U server chassis to keep critical components such as CPUs, memory modules, and PCIe devices within safe operating temperatures. The fan operates as part of the system thermal architecture and works with firmware and sensor-based controls to dynamically adjust speed based on workload and temperature conditions.
It is used in enterprise data centers where servers operate 24×7 under demanding workloads including virtualization, cloud infrastructure, database processing, and application hosting. The module ensures balanced airflow across the entire chassis, preventing thermal hotspots and maintaining consistent system performance. It also supports redundant operation so that cooling continues even if one fan module fails, ensuring system stability and uptime.

Typical Deployment Scenarios

Enterprise virtualization servers
Cloud and hosting infrastructure
Database and application workloads
High-density 2U rack environments
Mission-critical data center systems

Specifications

Compatibility / Ecosystem

HPE P49956-001 integrates into HPE ProLiant DL380 Gen11 server systems as part of the internal cooling subsystem. It works with system sensors and firmware-based thermal management to automatically adjust airflow based on workload and temperature readings. The fan module is designed for redundant cooling operation to ensure uninterrupted airflow even under partial fan failure. It is widely used in enterprise environments where thermal stability, high availability, and consistent performance are critical requirements.
