Chassis Intrusion Header
Figure 27, I shows the location of the chassis intrusion header.
This header can be
connected to a mechanical switch on the chassis to detect if the chassis cover is
removed.
This switch should be in the open position when the chassis cover is
installed and closed when the cover is removed.
Table 12 shows the pin assignments and signal names for the chassis intrusion header.
