Step 1
If the unit is rack-mounted, remove network wires and any cords connecting to the PIX security
appliance. 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 chassis cover from the PIX security appliance. Remove all screws holding the assembly in
place. Refer to the

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 boards into higher numbered sockets.
