The following information is intended for IBM Dealers and Authorized Servicers only. Customers attempting to follow any of the procedures below may void their warranty.

FRU Removals and Replacements
This section contains information about removals and replacements.

• Do not damage any parts. Only certified and trained personnel should service the computer.
• The arrows in this section show the direction of movement to remove a FRU, or to turn a screw to release the FRU. The arrows are marked in numeric order, in square callout, to show the correct sequence of removal.
• Any FRUs that must be removed before removing the failing FRU are listed at the top of the page.
• To replace a FRU, reverse the removal procedure and follow any notes that pertain to replacement.

• When replacing a FRU, use the correct screw size, as shown in the procedure.

Attention: The system board is sensitive to, and can be damaged by, electrostatic discharge. Establish personal grounding by touching a ground point with one hand before touching these units.

An electrostatic discharge (ESD) strap (P/N 6405959) must be used to establish personal grounding.
