Server and system compatibility cautions
This 48 W, two-wire unit is not a PC-header replacement. Provide a correctly rated 12 V supply/controller, retain chassis guards, and confirm the server does not require tach feedback or a specific fan-tray pinout.
- Disconnect power before service; retain the system’s guards and airflow direction, and keep cables clear of the impeller.
- Never infer pinout, control protocol, startup current or fan-failure reporting from wire color or a similar model. Follow the host service manual and the exact Delta drawing.
- After replacement, verify tach/fan-failure monitoring and cooling under a monitored system load before returning the host to service.
