Installing or removing the intrusion switch
The intrusion switch informs you that the server cover is not properly installed or closed by creating an event
in the system event log (SEL). You can purchase an intrusion switch from Lenovo.
Installing the intrusion switch
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 53.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Note: Use any documentation that comes with the intrusion switch and follow those instructions in addition
to the instructions in this topic.
To install the intrusion switch, do the following:
1. Remove all external media from the drives and turn off all attached devices and the server. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to
the server.
2. Prepare your server. See “Removing or extending the server from the rack cabinet” on page 55.
3. Remove the server cover. See “Removing the server cover” on page 55.
4. Touch the static-protective package that contains the intrusion switch to any unpainted surface on the
outside of the server. Then, take the intrusion switch out of the package.
5. Press the tab 1 outward as shown and then lower the intrusion switch until it is secured in the socket.
