Installing a Circuit Board

Before using this chapter, refer to "Opening a PIX Firewall Chassis," for instructions on how to open the case for each model of PIX Firewall. You can use the information in this chapter to install an interface card, such as Ethernet, Gigabit Ethernet, Token Ring, FDDI, Flash memory, or a Private Link VPN card.

The information in this chapter does not apply to the PIX 506.

The following statement applies to DC models:

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.

The following statement applies to both AC and DC models:

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

This chapter includes the following sections:

Installing a Circuit Board in a PIX 515

The information in this section refers to both the AC and DC models of the PIX 515.

Use the following steps to install a circuit board in a PIX 515:

Step 1 Locate the grounding strap from the accessory kit. Fasten the grounding strap to your wrist so that it contacts your bare skin. Attach the other end to bare metal inside the PIX 515 chassis as shown in Figure 7-1.

Figure 7-1: Attaching the PIX 515 Grounding Strap

Step 2 Remove the screws from the rear assembly on the left and put the assembly aside.

Step 3 Insert a board through the cage opening and into the slot as shown in Figure 7-2.

Figure 7-2: Inserting a Board into a PIX 515

Note When you insert a four-port Ethernet board in the slot, the end of the board's connector extends past the end of the slot. This does not affect the use or operation of the board.

Step 4 Attach the back cover plate making sure that the connecting flange on the board goes through the slot on the back cover plate as shown in Figure 7-3.

Step 5 Attach the screw to hold the board's connecting flange to the cover plate, and install the screws to attach the cover plate to the PIX 515 unit.

Step 6 Reattach the top cover.

Installing a Circuit Board in a PIX 520 and Earlier Model

Follow these steps to install a circuit board in a PIX 520 and earlier model:

Step 2 Insert the new board, as shown in Figure 7-5, and secure it using the screw provided with the board.

Figure 7-5: Installing the New Board

Step 3 Install the interface boards so that the leftmost board is the outside interface, as shown in Figure 7-6, the next board to the left is the inside interface, and any other interfaces to the left (away from the power supply) of the inside interface. If you have version 4.4 and a four-port Ethernet board, refer to the section, "PIX Firewall with a Four-Port Interface Card" in "Installing a PIX Firewall."

Note When adding a network interface or encryption card, install the new card in the first empty slot to the right of the existing network interface cards.

Figure 7-6: PIX Firewall Network Interfaces

Step 4 If you are installing a Private Link VPN board, insert the board in any remaining PCI slot after you have installed all of the required interface boards. Refer to Figure 7-7 for how a PCI slot compares to an ISA slot.

Figure 7-7: Identifying ISA and PCI Slots

Step 5 If you are installing a PIX Firewall Flash memory upgrade, remove the existing Flash card and place the new Flash card into the same ISA slot. If you are installing the PIX Firewall 16 MB Flash card, refer to the section, "PIX Firewall 16 MB Flash Card Installation" for more details.

Step 6 If you are installing an AccessPro router, the board requires two contiguous ISA slots.

Step 7 If you are installing a 4-port card, note that the board will overlap the slot connector on the motherboard. This does not affect the use or operation of the board. Figure 7-8 illustrates how this appears.

PIX Firewall 16 MB Flash Card Installation

To install the PIX Firewall 16 MB Flash card, remove the existing Flash card and place the new 16 MB Flash card into the same slot.

Note Before you replace a Flash card, be sure to write down your activation key and back up any information you may need to reconfigure the PIX Firewall.

To reinstall the software, refer to "Installing a PIX Firewall," or the Configuration Guide for the Cisco Secure PIX Firewall Version 5.1.

Note The jumper on the PIX Firewall 16 MB Flash card must not be removed or repositioned. The PIX Firewall system will not work if this jumper is moved.

The PIX Firewall 16 MB Flash card is shown in Figure 7-9.
