Removals and Replacements for machine type 2193,
2194, and 6345
BEFORE REMOVING ANY FRU, POWER-OFF THE
COMPUTER UNPLUG ALL POWER CORDS FROM
ELECTRICAL OUTLETS, THEN DISCONNECT ANY
INTERCONNECTING CABLES.
ATTENTION: The System board, processors, adapter cards,
DIMMs, and upgrade processors can be damaged by
electrostatic discharge. Use an electrostatic discharge (ESD)
strap to establish personal grounding. If you don’t have an
ESD strap, establish personal grounding by touching a
ground point with one hand before touching the static-
sensitive FRUs.
The Arrows in the removals and replacements procedures
show the direction of movement to remove a field-replaceable
unit (FRU), to turn a screw, or the direction to press a tab to
release the FRU.
Begin all removals by removing the cover (and rear cover, if
applicable). 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
failing FRU.
To replace a FRU, reverse the removal procedure and follow
any notes that pertain to replacement.
Before disconnecting any cables, note their location and
orientation. Reinstall any new FRUs with cabling in their
original location.
