DC Grounding, Connection, and Cable Specifications

To ground a DC-powered router, connect a grounding cable to earth ground and then attach
it to one of the chassis grounding points on the upper rear edge of the chassis. To supply
power to the router, connect power cables to a separate, dedicated DC power source for
each power supply and attach the cables to the quick connect terminals on each power
supply. Most sites distribute DC power through a main conduit that leads to frame-mounted
DC power distribution panels, one of which might be located at the top of the rack that
houses the router. A pair of cables (one input and one return) connects the quick connect
terminals to the power distribution panel.
Table 11 summarizes the specifications for the grounding and power cables, which you supply.
