Installing Circuit Boards in the Cisco PIX Firewall

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents.

Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Refer to the Regulatory Compliance and Safety Information for the Cisco PIX Firewall (Document Number 78-3733-02) for more information and translated warnings in European languages.

To install a circuit board in a PIX Firewall:

Step 1 Read the Regulatory Compliance and Safety Information for the Cisco PIX Firewall (Document Number 78-3733-02) for important safety information.

Step 2 Save the existing configuration to flash memory. For version 2, use the save command; for version 3, use the write flash command.

Step 3 Open the front access panel and power-off the unit as shown in Figure 1:

Figure 1 : Opening the Front Panel Provides Access to the Power Switch

Step 4 At the back of the PIX Firewall unit, remove the power cord and any cabling related to the board you are installing.

Step 5 Remove the unit from the equipment rack and place on a stable work surface.

Step 6 Detach the top access panel by using a Phillips-head screwdriver to remove the 16 screws securing the top panel (12 on top and 4 on the rear cover flange) as shown in Figure 2:

Figure 2 : Detach the Access Panel by Removing its 16 Screws

Step 7 Remove the top access panel.

Step 8 Remove the new circuit board from its bag.

Step 9 If you are replacing an existing circuit board, remove the screw that secures the board to the rear of the chassis for each board you are replacing as shown in Figure 3:

Figure 3 : Remove the Screw Holding the Board to the Rear of Chassis

Step 10 If you are replacing an existing board, remove each board and set it aside.

Step 11 Insert each new board in the appropriate slot so that the mounting bracket faces the rear of the unit as shown in Figure 4:

• If you are installing Ethernet boards, place them in the identical PCI slots (see Figure 5 in the next section) from which you removed the previous boards. Note that an empty slot is left between the two boards. Ensure that the Inside and Outside labels on the outside rear of the chassis correspond to the slots in which you install the boards.
  

• If you are installing Token-Ring boards, place them in the PCI slots (see Figure 5 in the next section) previously occupied by the Ethernet boards. (Token-Ring support will be provided in PIX Firewall version 3.) Note that an empty slot is left between the two boards. Ensure that the Inside and Outside labels on the outside rear of the chassis correspond to the slots in which you install the boards.
  

• If you are installing the Private Link encryption board, ensure both dip switches are in the off position and then insert the board in the leftmost ISA slot (see Figure 5 in the next section).

Step 12 Attach the screw to the mounting bracket.

Step 13 Attach the top access panel and its securing screws.

Step 14 Put the unit back on the equipment rack and plug in the cables and the power cord.

Step 15 Power-on the unit from the front access panel.

For configuration information, if you are using PIX Firewall version 2, refer to the Private Internet Exchange Reference Guide (Document Number 78-3362-02). If you are using version 3, refer to the Cisco PIX Firewall User Guide (Document Number 78-3728-01). Refer to the index in each guide to find information about the product you are installing.

Identifying Slot Types

Use the ISA slot to install the Private Link encryption board and the PCI slots to install either Ethernet or Token-Ring boards as shown in Figure 5:

Identifying Dip Switches

The Private Link encryption board dip switches are shown in Figure 6:
