DC Power Cables
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 field-wiring 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 field-wiring terminals to the power distribution panel.
Table 22 on page 168 summarizes the specifications for the DC power cables, which you
must supply.
