CPU Upgrade

Tools required

To accomplish adding a CPU to the computer the following tools are required:

• A Torx #10 driver. (This is the preferred tool)

• A flat blade screw driver. (this can be used if a Torx driver is not available)

• A3204-80004 ESD Kit (included with the CPU Upgrade Kit)

Adding a CPU Card

Be sure to observe all ESD precautions. The suggested time to perform the upgrade is at a non-peak

usage time for the computer. You must also know how many CPUs are already in the computer, this will

determine if you add to the available front slot (1) or the rear slots (2 and 3). Once you have identified

which slot or slots to add to, reference the appropriate procedures for adding a CPU card.

Before starting the actual installation of a CPU card there are certain preparation procedures to perform:

1. Log Off all users and stop all active applications that may be running.

2. Perform a system backup of the entire Operating System and data base. If this is not feasible, perform

a backup of the data base. (This should be done at a scheduled interval as common practice for

protecting any new data or changes to the existing data base.)

3. Perform a system shutdown. Enter "/etc/shutdown -h" at the prompt.

4. Turn the computer key switch to the STANDBY position.

5. At the rear of the computer, unplug the power cord.
