Intrusion Switch Assembly

Your server system includes two chassis intrusion switches that are located on the front and rear of the system chassis. The switches monitor the front door being opened and the left-hand side access panel being removed. To access the two intrusion switches you must remove the left-hand side access panel from the system chassis.

Note: The intrusion switch assembly consists of two intrusion switches with cables and a single cable connector.

To remove the intrusion switch assembly (see Figure 4-60), perform the following procedures:

1.Prepare your system for disassembly. See Preparing Your System for Disassembly and Reassembly earlier in this chapter.

2.Remove the left-hand side access panel of the system chassis. See Removing the Side Access Panel earlier in this chapter.

3.Tag and disconnect the intrusion switch cable from its mating connector on the system board. See Figure 4-60, C.

4.Remove the intrusion switch located on the front and the switch located at the rear of the chassis. See Figure 4-60, A and B. To release an intrusion switch squeeze its two plastic snap tabs together and slide it back until it is free of the chassis.

5.Carefully remove the intrusion switch assembly.
