P07202-001 is identified as a fan module in the official parts record.

Electrical ratings printed on the fan label can vary between interchangeable production builds. A different current or wattage marking does not automatically indicate incompatibility, but the server spare number, dimensions, connector, wiring, cable length and mounting orientation must match.

⚠️ Critical Compatibility Notice

This fan is intended for the ProLiant DL20 Gen10, also written as DL20 G10. It should not be ordered for a DL20 Gen10 Plus or DL20 Gen11 solely because the fan appears similar.

DL20 Gen10 Plus systems use a different fan family commonly referenced by P48439-001, P48354-001 or P48352-001.

Before ordering, verify all of the following:

• The installed fan carries P07202-001, P04002-001, P03999-001 or one of the listed fan-label references.
• The fan measures 40mm × 40mm × 28mm.
• The electrical rating is 12V DC.
• The cable terminates in the matching six-position locking connector.
• The wire order and connector keying match the installed fan.
• The cable length and mounting orientation are correct for the selected fan bay.

A generic 40mm 12V fan is not necessarily compatible. Server fan pinouts, locking connectors, speed-control signals and fault-monitoring circuits can differ even when the outside dimensions are identical.

✅ Confirmed Compatibility

Compatibility applies to configurations specifying P07202-001 or one of the interchangeable references listed above.

✔️ ProLiant DL20 Gen10 Server
✔️ ProLiant DL20 G10 Server
✔️ DL20 Gen10 1U rack-server configurations
✔️ DL20 Gen10 with two large-form-factor non-hot-plug drive bays
✔️ DL20 Gen10 with two large-form-factor hot-plug drive bays
✔️ DL20 Gen10 with four small-form-factor hot-plug drive bays
✔️ Fan positions 1, 2 and 3 when the installed module matches P07202-001
✔️ Systems using P04002-001 or P03999-001 fan assemblies
✔️ Systems using DBPF0428B2U-P005 fan-label builds
✔️ Systems using VF40281BX-Q400-Q9I fan-label builds

The supported drive-bay configurations are documented in the DL20 Gen10 configuration specifications. Always verify the installed fan number because component selection can vary by system configuration and service history.

⚙️ Installation and Fit Notes

• Shut down the operating system and disconnect every power cord before opening the server.
• Allow internal components to cool before servicing the fan area.
• Record the existing fan position, connector location and cable routing before removal.
• Remove the access panel and any air baffle obstructing the selected fan bay according to the service instructions.
• Replace one fan at a time to preserve the correct bay and cable assignment.
• Seat the locking connector completely without forcing it.
• Route the cable away from the fan blades and adjacent components.
• Reinstall every air baffle and the access panel before applying power.
• After startup, verify that the fan operates and that no fan fault is reported by the system-management controller.
• If a fan warning remains, shut the server down and recheck the connector, cable routing and complete part number.
• Do not operate the server with a required fan disconnected or removed.
