Chapter 4 PIX 515/515E

Installing a PIX 515/515E 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 515/515E 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 Power off the PIX 515/515E by checking the power switch at the rear of the unit.

Step 4 As shown in Figure 4-22, the PIX 515/515E is equipped with two grounding holes at the back of the

unit, which you can use to connect a two-hole grounding lug to the PIX 515/515E. Use 8-32 screws to

connect a copper standard barrel grounding lug to the holes. The PIX 515/515E requires a lug where

the distance between the center of each hole is 0.56 inches. A lug is not supplied with the PIX 515/515E.

Step 5 Power off the unit. 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 515/515E.

Step 7 Insert the ground wire into the connector for the earth ground and tighten the screw on the connector.

Refer to Figure 4-22 and using the same method as for the ground wire, connect the negative wire and

then the positive wire.

Step 8 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 Install any remaining interface boards as described in “Installing a Circuit Board in a PIX 515/515E”.
