away from the display and toward the rack rail (see B in the diagram).
Result: The module power connector unseats from the power
connector located behind the display and LEDs.
Slide the failed cooling fan module out of the chassis (see C in the
diagram).
Align the replacement cooling fan module tabs with the four support
slots on the chassis.
Ensure that the module is oriented with the thumbscrew, and insert
the tabs into the supporting slots of the chassis.
Slide the cooling fan module toward the front panel display and into
position.
Result: The fan module connects with slight resistance. The fans
rotate and pull air into the chassis. The cooling fan LED goes out.
