To ensure that there is minimum susceptibility to EMI and minimum radiation, it is important
that the card mounting bracket be properly screwed into place and that there be a positive
chassis ground. Also, proper EMI cabling techniques (cable connect to chassis ground at the
aperture, shielded twisted-pair wiring, etc.) should be used for the input/output wiring.
