meet FCC Class B requirements, even if no device or a low-speed USB device is
attached to the cable. Use a shielded cable that meets the requirements for a
full-speed USB device.

Figure 18, G on page 43 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 13 shows the pin assignments
for the chassis intrusion header.
