FRU Removals and Replacements (3546)
FRU Removals and Replacements
This section contains information on removals and replacements, and
locations.
- The arrows in the removals and replacements show
the direction of movement to remove a field replaceable unit (FRU), or
to turn a screw to release
the FRU. The arrows are marked in numeric order to
show the correct sequence of removal.
- When other FRUs must be removed before 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 connections and arrangement information.
Before removing any FRU, turn off Dock II, remove the computer,
unplug all power cords
from electrical outlets,
then disconnect any interconnecting cables.
In the U.K., by law, the telephone cable must be connected after
or disconnected before the power cord.
WARNING
The main board, adapters, and circuit boards on the drives 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 must be used to establish
personal grounding.
