Notes:
1. Read “Before you begin” on page 41, “Handling electrostatic discharge-sensitive
devices” on page 132, and the safety notices at “Safety information” on
page 129.
2. When replacing the system board, you must either update the system with the
latest firmware or restore the pre-existing firmware that the customer provides
on a diskette or CD image.
Complete the following steps to remove the system board:
1. Turn off the computer and attached devices; then, disconnect all external cables
and power cords.
2. Remove the cover (see “Removing the cover of the 6226” on page 60).
3. Remove any of the following components that are installed on the system
board:

Microprocessor (see “Microprocessor/fan-sink assembly” on page 91).
Important: If you plan to reinstall an existing microprocessor to the new
system board, be careful when handling the adhesive material on
the microprocessor. If the adhesive material on the
microprocessor will be reused, do not contaminate it. If
replacement adhesive material is provided with the replacement
system board, be sure to remove all traces of existing adhesive
material from the microprocessor before applying the new
adhesive material.
v Adapters (see “Working with adapters” on page 60).
v DIMMs (see “Installing memory modules” on page 70).
4. Disconnect all internal system board cables.
Note: The power supply has been removed in the illustration for purposes of
