HPE ML350 GEN11 Redundant FAN KIT - P47219-B21

HPE P47219-B21 Redundant Fan Kit for ProLiant ML350 Gen11

Overview

The HPE P47219-B21 is a redundant fan kit designed to maintain continuous airflow in the ProLiant ML350 Gen11 tower server. In environments where the ML350 Gen11 runs compute-intensive or storage-heavy workloads around the clock, a single fan failure without redundancy means an immediate thermal risk and potential unplanned downtime. Installing the P47219-B21 adds a spare fan module to the chassis so the system continues operating at full thermal capacity if one fan fails — keeping the server online until a scheduled maintenance window rather than forcing an emergency shutdown. This is the correct kit for data center operators, on-premises IT teams, and integrators who cannot afford the downtime exposure of a non-redundant cooling configuration.

Compatibility

The P47219-B21 is designed specifically for the HPE ProLiant ML350 Gen11 tower server. It is not a universal fan kit — confirm your chassis is the Gen11 revision before ordering, as Gen10 and Gen10 Plus variants use different fan assemblies. If you are configuring or expanding an on-premises server for surveillance recording or edge compute and are running an ML350 Gen11 as your platform, this kit is the correct thermal redundancy component for that chassis.

Installation Notes

The kit ships at 2.15 lb and measures 10.80 x 8.10 x 4.10 in — size consistent with a full fan-module assembly rather than a single fan blade. Installation follows standard HPE tool-free fan bay procedure for the ML350 Gen11 chassis. Ensure the server is either powered down or in a live-swap-capable state per HPE's hot-plug guidance for this platform before seating the module. Country of origin is CN.
