Removing and replacing a FRU
This section presents information and drawings for use in
removing and replacing a FRU. Be sure to observe the fol-
lowing general rules:
1. Do not try to service the computer unless you have
been trained and certified. An untrained person runs
the risk of damaging parts.
2. Before replacing any FRU, review “FRU replacement
notices” on page 42
3. Begin by removing any FRUs that have to be
removed before the failing FRU. Any such FRUs are
listed at the top of the page. Remove them in the
order in which they are listed.
4. Follow the correct sequence in the steps for removing
the FRU, as indicated in the drawings by the numbers
in square callouts.
5. When turning a screw to replace a FRU, turn it in the
direction indicated by the arrow in the drawing.
6. When removing the FRU, move it in the direction indi-
cated by the arrow in the drawing.
7. To put the new FRU in place, reverse the removal
procedure and follow any notes that pertain to
replacement. For information about connecting and
arranging internal cables, see “Locations” on
page 66.
8. When replacing a FRU, use the correct screw as
shown in the procedures.
CAUTION:
Before removing any FRU, power off the computer,
unplug all power cords from electrical outlets, remove
the battery pack, and then disconnect any intercon-
necting cables.
CAUTION:
Do not disassemble it, throw it into fire or water, or
short-circuit it. Dispose of the battery pack as
required by local ordinances or regulations.
