MX240 Chassis Grounding Points Specifications
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.
See Figure 16 on page 62 for connecting AC power to the router and
DC power to the router.
NOTE: Additional grounding is provided to an AC-powered router when you plug its power
supplies into grounded AC power receptacles.
