8.0 Removals and Replacements
The arrows in the removals and replacements section show the direction of
movement to remove a FRU, to turn a screw, or to press a tab to release
the FRU. The arrows are marked in numeric order to show the correct
sequence of removal.
When other FRUs must be removed prior to removing the failing FRU, they
are listed at the top of the page. Go to the removal procedure for each
FRU listed, remove the FRU, and then continue with the removal of the
failing FRU.
To replace a FRU, reverse the removal procedure and follow any notes that
pertain to replacement. See "Locations" for internal cable connection and
arrangement information.
CAUTION:
Before removing any field replaceable unit (FRU), power-off the system,
unplug all power cords from electrical outlets, and disconnect any
interconnecting cables.
Warning: The system board, adapters, memory modules, and the math
coprocessor are sensitive to, and can be damaged by, electrostatic
discharge. Establish personal grounding by touching a ground point with
one hand before touching these units.
Note: An electrostatic discharge (ESD) strap may be used to establish
personal grounding.
