NOTICE
To prevent USG overheating, replace the fan module within 1 minute.
Procedure
Step 1
Wear an ESD wrist strap.
Step 2
Remove the faulty fan module.
Use the Phillips screwdriver to loose the screws on the fan module. Hold the handlers to pull
the fan module out of the chassis for a little bit. Remove the fan module slightly from the
chassis after all fans stop running.
CAUTION
When removing the fan module, wait for the fans to stop rotating before holding the bottom
of the fan module to avoid being scratched by the rotating fans. After the fans stop rotating,
do not touch the fan blades and the rotation axis. Otherwise, the fan balancing may be
damaged, resulting in increased noise when the fans are running.
