To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, the router must be adequately grounded before power is connected.
To ground AC-powered and DC-powered routers, you must connect a grounding cable
to earth ground and then attach it to the chassis grounding points using the two screws
provided.
Two threaded inserts (PEM nuts) are provided on the upper rear of the chassis for
connecting the router to earth ground. The grounding points fit UNC 1/4–20 screws
(American). The grounding points are spaced at 0.625-in. (15.86-mm) centers.
NOTE: Additional grounding is provided to an AC-powered router when you
plug its power supplies into grounded AC power receptacles.
