Grounding-plate method

In shared ground facilities complying with the International Electrotechnical
Commission (IEC) standards, noise generated by other electronic facilities such as
electronic devices, air conditioning facilities and elevators may penetrate the server
systems through the shared ground facilities' cables. In some cases, this can be
prevented by the grounding-plate method. In the grounding-plate method, a
grounding plate (see note below) is laid under the raised floor near the power
distribution panel, as shown in
equipment. For whether the site requires implementation of grounding-plate, consult
with the Facility section.
