This document describes how to install Cisco's PIX Firewall 520 DC power model.
To install the PIX Firewall DC power model:
Step 1 Read the Regulatory Compliance and Safety Information for the PIX Firewall supplied with your unit.
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 Power off the PIX Firewall from the switch at the rear of the unit.
Step 4 As shown in Figure 1, the PIX Firewall 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 Firewall. Use the 10-32 nuts provided with the PIX Firewall to connect a copper standard barrel grounding lug to the studs. The PIX Firewall requires a lug where the distance between the center of each hole is 0.56 inches. A lug is not supplied with the PIX Firewall.
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 Firewall.
Step 7 Refer to Figure 2 and insert the wire into the connector for the earth ground and tighten the screw on the connector. Then connect the negative wire and then the positive wire using the same method as for the ground wire.
Step 8 Reconnect power to the PIX Firewall. After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position.
Step 9 Insert the PIX Firewall system diskette in the drive at the front of the unit.
Step 10 Connect the network cables ensuring that the outside network cable is connected to the leftmost interface board, the inside network cable connected to the next interface board to the right of the outside network, and any perimeter cables connected to the right of the inside interface board.
Step 11 Power on the unit from the switch at the rear of the unit.
Your unit is now ready to configure. If your PIX Firewall uses software version 4.0 or 4.1, refer to the PIX Firewall Series Configuration Guide. If it uses version 4.2, refer to the Configuration Guide for the PIX Firewall.
