Installing the DC Model Chapter 4 Maintenance and Upgrade Procedures Step 1 Step 2 Step 3 Read the Regulatory Compliance and Safety Information for the Cisco ASA 5500 Series document. Terminate the DC input wiring on a DC source capable of supplying at least 15 amps. A 15-amp circuit breaker is required at the 48 VDC facility power source. An easily accessible disconnect device should be incorporated into the facility wiring. Locate the DC-input terminal box, see Figure 4-9. Figure 4-9 DC-Input Terminal Box + - 119640 1 2 3 4 1 Negative 3 Ground 2 Positive 4 On/Off switch Step 4 Step 5 Step 6 Step 7 Power off the adaptive security appliance. 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. Remove the DC power supply plastic shield. The adaptive security appliance is equipped with two grounding holes at the side of the chassis, which you can use to connect a two-hole grounding lug to the adaptive security appliance. Use 8-32 screws to connect a copper standard barrel grounding lug to the holes. The adaptive security appliance requires a lug where the distance between the center of each hole is 0.56 inches. A lug is not supplied with the adaptive security appliance. Strip the ends of the wires for insertion into the power connect lugs on the adaptive security appliance.
