Connecting DC-Input Power to a Cisco 7304 Router
Note
The color coding of the DC-input power supply leads depends on the color coding of the DC power
source at your site. Typically, green or green/yellow is used for ground. Make certain that the lead color
coding you choose for the DC-input power supply matches the lead color coding used at the DC power
source.
Warning
Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure
that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker
on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and
tape the switch handle of the circuit breaker in the OFF position.
Warning
When installing the unit, the ground connection must always be made first and disconnected last.
