Notes:
• Make sure that you use the correct screw. If you have a torque screwdriver, tighten all screws firmly to the
torque shown in the table for each step in Chapter 7 "Removing and replacing a FRU" on page 35. Never
use a screw that you removed. Use a new one. Make sure that all of the screws are tightened firmly.
• Ensure torque screwdrivers are calibrated correctly following country specifications.
