Removals and Replacements
See Safety Notices (Multi-Lingual Translations) on page VII
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, SIMMs, 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 shows the direction
of movement to remove a field-replaceable unit (FRU), to turn a screw, or
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 the failing FRU.
To replace a FRU, reverse the removal procedure and follow any notes that
pertains to replacement.
Before disconnecting any cables, note their location and orientation. Reinstall
any new FRUs with cabling in their original locations.
