*Common GND pins mate to a GIGA assembly with a ground plate. The GIGA assembly is an
enhanced electrical performance receptacle and plug from AMP that includes receptacles
loaded with contacts for grounding circuits at 9 or 10 signal circuits. These ground contacts
mate with grounding plates on both sides of the plug assemblies.
