Warning This product relies on the building’s installation for short-circuit (over current) protection. Ensure that

the protective device is rated not greater than: 15A, 120VAC (10A, 240VAC). Statement 1005

Connecting to DC Power

If your router has a DC-input power supply, follow the directions in this section for proper wiring. A router with a DC-input power supply has a terminal block for the DC power connections.

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 4-2summarizes 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.
