DC Wiring Requirements for Cisco 1900 Series Routers

A Cisco 1921 router with a DC-input power supply requires copper wire and crimp-type terminals for

the power connections. Table 4-2 summarizes the wiring requirements.

You can connect a single DC power source to either the A input or the B input. If there are dual power

sources, connect one source to the A input and one source to the B input; both sources must be the same

polarity and voltage.
