NOTE: We recommend that you provide at least 10.5 A @ 24 VDC and use a
facility circuit breaker rated for 10 A minimum. Doing so enables you to operate
the router in any configuration without upgrading the power infrastructure,
and allows the router to function at full capacity using multiple power
supplies.

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 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 (see
Figure 12 on page 46).
Two threaded holes are provided on the front of the router chassis for connecting the
router to earth ground. The grounding points fit 0.5-inch-long SAE 10-32 screws
(American). The grounding points are spaced at 0.625-in. (15.86-mm) centers.
