Installing a Circuit Board in a PIX 515


Note   Installing a circuit board in a PIX 515 requires the use of the PIX-515-UR unrestricted feature license to access the boards from the PIX 515. Without this feature license, any board you install in the PIX 515 is ignored.


To install a circuit board in a PIX 515:


Step 1 Locate the grounding strap from the accessory kit and attach it to bare metal inside the PIX 515 case as shown in .

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 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 .

Step 5 Attach the screw to hold the board's connecting flange to the cover plate, and 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

To install a circuit board in a PIX 520 and earlier model:


Step 1 Locate the wrist grounding strap that accompanied the memory strip and connect one end to the PIX Firewall chassis, as shown in , and securely attach the other to your wrist so it contacts your bare skin.

Step 2 Insert the new board, as shown in , 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 lefttmost board is the outside interface, as shown in , 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 "."


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.

Step 4 If you are installing the ISA version of the Private Link VPN board (refer to for how an ISA slot appears), ensure both dip switches, as shown in , are in the off (open) position and then insert the board in the leftmost ISA slot.

Note That Dip Switch is Off When in "Open" Position

Step 5 If you are installing the PCI version of the Private Link VPN board, insert the board in any remaining PCI slot after you install all required interface boards.

Step 6 If you are installing the PIX Firewall Flash memory upgrade, place the new circuit board in the same slot from which you remove the existing circuit board.

Step 7 If you are installing an AccessPro router, the board requires two contiguous ISA slots. If you have an AccessPro router installed in the PIX Firewall, the Private Link board can be in the rightmost ISA slot.
