Installing a Memory Upgrade
Memory Installation Steps
Complete these steps to install additional system memory:
Step 1 If the unit is rack-mounted, remove network wires and any cords connecting to the PIX Firewall unit.
The PIX 520 should be removed from the rack and placed on a stable working surface. Ensure that the
unit is unplugged from its power source.
Step 2 Unpack the items in the memory upgrade kit.
Remove the top panel from the PIX Firewall unit. Remove all screws holding the assembly in place.
Refer to “Installing LAN-Based Failover” for information on how to remove and replace the top panel.
Step 3 Determine the location of your system memory sockets (see Figure 5-14).
Step 4 Use the markings on the motherboard to determine the socket numbers. Always install the first memory
board into the lowest socket number. Progressively add memory boards into higher numbered sockets.

Step 5
Locate the wrist grounding strap in the accessory kit and connect one end to the unit as shown in
Figure 5-17, or to the PIX Firewall chassis, and securely attach the other to your wrist so it contacts your
bare skin.
Step 6 With the wrist strap on your wrist, carefully grasp the memory strip from either end. Note that a DIMM
strip has notches.
Step 7 To install a DIMM strip:
• Remove the old memory strip by opening the two plastic wing connectors, and pulling the old strip
up. Discard the old strip.
• When installing the memory strip in the PIX 520, install the new strip in Bank 0 as shown in
Figure 5-15 and Figure 5-16, by opening the two plastic wing connectors, inserting the strip, and
closing the wing connectors.
