Installation Addendum for the
DC PIX 515 Version 4.4

August 1999

This document describes how to install the Cisco PIX 515 DC power model.

Note Only a DC power source that complies with the safety extra low voltage (SELV) requirements in UL1950, CSA C22.2 Number 950, EN 60950, and IEC 950 can be connected to a PIX 515 DC-input power supply.

Note PIX 515 models equipped with DC-input power supplies are only intended for installation in a restricted access location in accordance with Articles 110-16, 110-17, and 110-18 of the National Electric Code ANSI/ NFPA 70.

Note When creating the wiring to attach to the PIX 515 DC unit, Cisco recommends that you only use a minimum of 12 gauge wire to connect the PIX 515 unit's positive, negative, and earth ground, and use a minimum of 8 gauge wire for connecting a double grounding lug to the chassis or mounting rack ground.

To install the PIX 515 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 Turn off the PIX 515 from the switch at the rear of the unit.

Step 4 As shown in Figure 1, the PIX 515 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. Use the 8-32 screws provided with the PIX 515 to connect a copper standard barrel grounding lug to the studs. The PIX 515 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.

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 515.

Step 7 Refer to Figure 1 and insert the wire into the connector for the earth ground and tighten the screw on the connector. Using the same method as for the ground wire, connect the negative wire and then the positive wire.

Step 8 Reconnect power to the PIX 515. After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate the power by moving the handle of the circuit breaker to the ON position.

Step 9 Connect the network cables. For additional information, refer to the Installation Guide for the PIX Firewall.

Step 10 Turn on the unit from the switch at the rear of the unit.

Step 11 Your unit is now ready to configure. Refer to the Configuration Guide for the PIX Firewall for more information.
