NOTE:
For the system shipped with a WWAN card, there is an L-shaped bracket (P-sensor bracket) that covers the four
WWAN LTE antenna cable connections to the system board. The screw that secures the bracket to the system also
helps secure the fan to the system. Technicians must first remove the bracket before removing the fan and then
reinstall the bracket after the fan is reinstalled.
