Installing the PIX 520 DC Model
Warning Before performing any of the following procedures, 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.
Complete these steps to install the PIX 520 DC power model:
Step 1 Read the Regulatory Compliance and Safety Information for the Cisco PIX Firewall document.
Step 2 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.
Step 3 Be sure the PIX 520 power is off by checking the power switch at the rear of the unit.
Step 4 As shown in Figure 5-24, the PIX 520 is equipped with two grounding studs at the back of the unit, which
you can use to connect a two-hole grounding lug to the PIX 520. Use the 10-32 nuts provided with the
PIX 520 to connect a copper standard barrel grounding lug to the studs. The PIX 520 requires a lug where
the distance between the center of each hole is 0.56 inches. A lug is not supplied with the PIX 520.

Step 5
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.
Step 6 Strip the ends of the wires for insertion into the power connect lugs on the PIX 520.
Step 7 Insert the ground wire into the connector for the earth ground and tighten the screw on the connector (see
Figure 5-25). Using the same method as for the ground wire, connect the negative wire and then the
positive wire.
