Installing a Memory Upgrade
Memory Installation Steps
PIX software Version 7.0 requires a minimum of 128 MB of memory with the Restricted license, and
256 MB of memory with the Unrestricted and Failover licenses.
To install additional system memory, perform the following steps:
Step 1 If the unit is rack-mounted, remove network wires and any cords connecting to the PIX security
appliance. Ensure that the unit is unplugged from its power source.
Step 2 Unpack the items in the memory upgrade kit.
Step 3 Remove the component tray and all the screws holding the assembly in place. Refer to the “Removing
and Replacing the PIX 525 Chassis Cover” section on page 6-9 for more information.
Step 4 Determine the location of your system memory sockets (see Figure 6-11).
Step 5 Use the markings on the motherboard to determine the socket numbers. Always install the first memory
strip into the lowest socket number. Progressively add memory strips into higher numbered sockets.

Step 6 Locate the wrist grounding strap in the accessory kit and connect one end to the unit or to the
PIX security appliance chassis, and securely attach the other to your wrist so it contacts your bare skin.
Step 7 With the wrist strap on your wrist, carefully grasp the memory strip from either end. Note that a DIMM
strip has notches.
Step 8 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 a PIX 525, install the new strip in Bank 0 as shown in
Figure 6-12 and Figure 6-13, by opening the two plastic wing connectors, inserting the strip, and
closing the wing connectors.
