Install the intrusion switch

Follow instructions in this section to install the intrusion switch.

About this task

  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.


  1. Touch the static-protective package that contains the new part to any unpainted surface on the outside of the server. Then, take the new part out of the package and place it on a static-protective surface.
  2. Install the intrusion switch onto the fan cage.

    Ensure that the intrusion switch cable is routed through the cable clip and the pre-cut slots on the foam and fan cage bottom. Otherwise, the cable may slide under the fan cage, the contact surface between the fan cage and the system board assembly may get uneven, and the fan connection may get loose.
