Installing A Second Processor - HP D7171A - NetServer - LPr Installation Manual

Installing a Second Processor

CAUTION) Do not open the new processor's protective bag or
remove it from the bag until you are ready to install it.
Always wear a wrist-strap and use a static-dissipating
work surface connected to the chassis when handling
components. Ensure the metal of the wrist strap contacts
your skin.
Before you remove a processor from the anti-static
bag, touch a grounded, unpainted metal surface on
the HP Netserver to discharge static electricity.
NOTE) ) No speed switch settings are required for the supported
processors (1.13 or 1.26 GHz) in the HP Netserver.
These processors rely on the internal settings within the
processors and do not rely on external switch settings on
the system board.
Terminator
ZIF
Lever
NOTE ) Retain the terminator for future use. The Netserver will
not operate properly if using only one processor with no
terminator installed.
CAUTION) Once the system has been turned on, heat from the
processor activates the thermal patch which bonds the
heatsink to the processor. Removing the heatsink
destroys this bond and a new thermal patch will be
required.
Each time the heatsink is removed from the processor,
some of the thermal material is removed from the patch.
NOTE ) If you are re-installing a heatsink on the processor, you
may need to scrap off any thermal material left on top of
the processor chip. Use your fingernail to scrap off the
material, but ensure you are grounded with a
static-dissipating wrist strap.

(Continued)
To prevent overheating and possible damage to the
processor, inspect the thermal patch to ensure the
thermal material covers the whole patch. If not, you must
remove the old patch and replace it with a new thermal
patch.

If good contact is not made the processor can overheat
and possible damage may occur.
Hold Down
To prevent scratching off some of the thermal material,
do not slide the heatsink around once it is on the
processor. Rocking it slightly to install both sides of the
latch is acceptable.
