Chapter 2 Hardware Installation Process
Installing the Central Process Unit (CPU)
CPU Installation
1. Unlock the CPU socket by pulling the lever up to a 90-degree angle.
2. Position the CPU above the socket such that the marked corner (pin1) matches the corner near the base
of the lever.
3. Place the CPU into the socket. If the CPU is unable to insert properly, check its orientation and attempt to
re-install.
Warning! Do not force the CPU into the socket. Doing so will prompt bending of the pins and create
damage to the CPU.
4. Close the socket by lowering the lever and locking the lever in place.

Installing Memory Modules
1. Push the white retaining clips on each of the memory socket outwards.
2. Match the notches on the contact edge of the memory module to the ridges in the memory socket.
3. Insert the memory module vertically into place. When properly inserted, the white retaining clips will move
inward to lock in the module.
4. Repeat installation process when adding additional modules.
