To disconnect DC-input power from a Cisco 7200 VXR router, complete the following steps.

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. Statement 332
